# Security Policy
|
||||
|
||||
LangChain has a large ecosystem of integrations with various external resources like local and remote file systems, APIs and databases. These integrations allow developers to create versatile applications that combine the power of LLMs with the ability to access, interact with and manipulate external resources.
|
||||
|
||||
## Best practices
|
||||
|
||||
When building such applications developers should remember to follow good security practices:
|
||||
|
||||
* [**Limit Permissions**](https://en.wikipedia.org/wiki/Principle_of_least_privilege): Scope permissions specifically to the application's need. Granting broad or excessive permissions can introduce significant security vulnerabilities. To avoid such vulnerabilities, consider using read-only credentials, disallowing access to sensitive resources, using sandboxing techniques (such as running inside a container), specifying proxy configurations to control external requests, etc. as appropriate for your application.
|
||||
* **Anticipate Potential Misuse**: Just as humans can err, so can Large Language Models (LLMs). Always assume that any system access or credentials may be used in any way allowed by the permissions they are assigned. For example, if a pair of database credentials allows deleting data, it’s safest to assume that any LLM able to use those credentials may in fact delete data.
|
||||
* [**Defense in Depth**](https://en.wikipedia.org/wiki/Defense_in_depth_(computing)): No security technique is perfect. Fine-tuning and good chain design can reduce, but not eliminate, the odds that a Large Language Model (LLM) may make a mistake. It’s best to combine multiple layered security approaches rather than relying on any single layer of defense to ensure security. For example: use both read-only permissions and sandboxing to ensure that LLMs are only able to access data that is explicitly meant for them to use.
|
||||
|
||||
Risks of not doing so include, but are not limited to:
|
||||
* Data corruption or loss.
|
||||
* Unauthorized access to confidential information.
|
||||
* Compromised performance or availability of critical resources.
|
||||
|
||||
Example scenarios with mitigation strategies:
|
||||
|
||||
* A user may ask an agent with access to the file system to delete files that should not be deleted or read the content of files that contain sensitive information. To mitigate, limit the agent to only use a specific directory and only allow it to read or write files that are safe to read or write. Consider further sandboxing the agent by running it in a container.
|
||||
* A user may ask an agent with write access to an external API to write malicious data to the API, or delete data from that API. To mitigate, give the agent read-only API keys, or limit it to only use endpoints that are already resistant to such misuse.
|
||||
* A user may ask an agent with access to a database to drop a table or mutate the schema. To mitigate, scope the credentials to only the tables that the agent needs to access and consider issuing READ-ONLY credentials.
|
||||
|
||||
If you're building applications that access external resources like file systems, APIs
|
||||
or databases, consider speaking with your company's security team to determine how to best
|
||||
design and secure your applications.

This guide walks through how to implement and test a custom [chat model](/docs/concepts/chat_models) that you have developed.
|
||||
|
||||
For testing, we will rely on the `langchain-tests` dependency we added in the previous [bootstrapping guide](/docs/contributing/how_to/integrations/package).
|
||||
|
||||
## Implementation
|
||||
|
||||
Let's say you're building a simple integration package that provides a `ChatParrotLink`
|
||||
chat model integration for LangChain. Here's a simple example of what your project
|
||||
structure might look like:
|
||||
|
||||
```plaintext
|
||||
langchain-parrot-link/
|
||||
├── langchain_parrot_link/
|
||||
│ ├── __init__.py
|
||||
│ └── chat_models.py
|
||||
├── tests/
|
||||
│ ├── __init__.py
|
||||
│ └── test_chat_models.py
|
||||
├── pyproject.toml
|
||||
└── README.md
|
||||
```
|
||||
|
||||
Following the [bootstrapping guide](/docs/contributing/how_to/integrations/package),
|
||||
all of these files should already exist, except for
|
||||
`chat_models.py` and `test_chat_models.py`. We will implement these files in this guide.
|
||||
|
||||
To implement `chat_models.py`, we copy the [implementation](/docs/how_to/custom_chat_model/#implementation) from our
|
||||
[Custom Chat Model Guide](/docs/how_to/custom_chat_model). Refer to that guide for more detail.

## Testing
|
||||
|
||||
To implement our test files, we will subclass test classes from the `langchain_tests` package. These test classes contain the tests that will be run. We will just need to configure what model is tested, what parameters it is tested with, and specify any tests that should be skipped.
|
||||
|
||||
### Setup
|
||||
|
||||
First we need to install certain dependencies. These include:
|
||||
|
||||
- `pytest`: For running tests
|
||||
- `pytest-socket`: For running unit tests
|
||||
- `pytest-asyncio`: For testing async functionality
|
||||
- `langchain-tests`: For importing standard tests
|
||||
- `langchain-core`: This should already be installed, but is needed to define our integration.
|
||||
|
||||
If you followed the previous [bootstrapping guide](/docs/contributing/how_to/integrations/package/), these should already be installed.
|
||||
|
||||
### Add and configure standard tests
|
||||
There are two namespaces in the langchain-tests package:
|
||||
|
||||
[unit tests](../../../concepts/testing.mdx#unit-tests) (`langchain_tests.unit_tests`): designed to be used to test the component in isolation and without access to external services
|
||||
[integration tests](../../../concepts/testing.mdx#integration-tests) (`langchain_tests.integration_tests`): designed to be used to test the component with access to external services (in particular, the external service that the component is designed to interact with).
|
||||
|
||||
Both types of tests are implemented as [pytest class-based test suites](https://docs.pytest.org/en/7.1.x/getting-started.html#group-multiple-tests-in-a-class).
|
||||
|
||||
By subclassing the base classes for each type of standard test (see below), you get all of the standard tests for that type, and you can override the properties that the test suite uses to configure the tests.
|
||||
|
||||
Here's how you would configure the standard unit tests for the custom chat model:
|
||||
|
||||
```python
|
||||
# title="tests/unit_tests/test_chat_models.py"
|
||||
from typing import Type
|
||||
|
||||
from my_package.chat_models import MyChatModel
|
||||
from langchain_tests.unit_tests import ChatModelUnitTests
|
||||
|
||||
|
||||
class TestChatParrotLinkUnit(ChatModelUnitTests):
|
||||
@property
|
||||
def chat_model_class(self) -> Type[MyChatModel]:
|
||||
return MyChatModel
|
||||
|
||||
@property
|
||||
def chat_model_params(self) -> dict:
|
||||
# These should be parameters used to initialize your integration for testing
|
||||
return {
|
||||
"model": "bird-brain-001",
|
||||
"temperature": 0,
|
||||
"parrot_buffer_length": 50,
|
||||
}
|
||||
```
|
||||
|
||||
And here is the corresponding snippet for integration tests:
|
||||
|
||||
```python
|
||||
# title="tests/integration_tests/test_chat_models.py"
|
||||
from typing import Type
|
||||
|
||||
from my_package.chat_models import MyChatModel
|
||||
from langchain_tests.integration_tests import ChatModelIntegrationTests
|
||||
|
||||
|
||||
class TestChatParrotLinkIntegration(ChatModelIntegrationTests):
|
||||
@property
|
||||
def chat_model_class(self) -> Type[MyChatModel]:
|
||||
return MyChatModel
|
||||
|
||||
@property
|
||||
def chat_model_params(self) -> dict:
|
||||
# These should be parameters used to initialize your integration for testing
|
||||
return {
|
||||
"model": "bird-brain-001",
|
||||
"temperature": 0,
|
||||
"parrot_buffer_length": 50,
|
||||
}
|
||||
```
|
||||
|
||||
These two snippets should be written into `tests/unit_tests/test_chat_models.py` and `tests/integration_tests/test_chat_models.py`, respectively.
|
||||
|
||||
:::note
|
||||
|
||||
LangChain standard tests test a range of behaviors, from the most basic requirements to optional capabilities like multi-modal support. The above implementation will likely need to be updated to specify any tests that should be ignored. See [below](#skipping-tests) for detail.
|
||||
|
||||
:::
|
||||
|
||||
### Run standard tests
|
||||
|
||||
After setting tests up, you would run these with the following commands from your project root:
|
||||
|
||||
```shell
|
||||
# run unit tests without network access
|
||||
pytest --disable-socket --allow-unix-socket --asyncio-mode=auto tests/unit_tests
|
||||
|
||||
# run integration tests
|
||||
pytest --asyncio-mode=auto tests/integration_tests
|
||||
```
|
||||
|
||||
Our objective is for the pytest run to be successful. That is,
|
||||
|
||||
1. If a feature is intended to be supported by the model, it passes;
|
||||
2. If a feature is not intended to be supported by the model, it is skipped.
|
||||
|
||||
### Skipping tests
|
||||
|
||||
LangChain standard tests test a range of behaviors, from the most basic requirements (generating a response to a query) to optional capabilities like multi-modal support, tool-calling, or support for messages generated from other providers. Tests for "optional" capabilities are controlled via a [set of properties](https://python.langchain.com/api_reference/standard_tests/unit_tests/langchain_tests.unit_tests.chat_models.ChatModelTests.html) that can be overridden on the test model subclass.
|
||||
|
||||
|
||||
### Test suite information and troubleshooting
|
||||
|
||||
What tests are run to test this integration?
|
||||
|
||||
If a test fails, what does that mean?
|
||||
|
||||
You can find information on the tests run for this integration in the [Standard Tests API Reference](https://python.langchain.com/api_reference/standard_tests/index.html).

## Standard Tests
|
||||
|
||||
Testing is a critical part of the development process that ensures your code works as expected and meets the desired quality standards.
|
||||
In the LangChain ecosystem, we have 2 main types of tests: **unit tests** and **integration tests**.
|
||||
These standard tests help maintain compatibility between different components and ensure reliability.
|
||||
|
||||
**Unit Tests**: Unit tests are designed to validate the smallest parts of your code—individual functions or methods—ensuring they work as expected in isolation. They do not rely on external systems or integrations.
|
||||
|
||||
**Integration Tests**: Integration tests validate that multiple components or systems work together as expected. For tools or integrations relying on external services, these tests often ensure end-to-end functionality.
|
||||
|
||||
Each type of integration has its own set of standard tests. Please see the relevant [component-specific guide](#component-specific-guides) for details on testing your integration.
|
||||
|
||||
## Co-Marketing
|
||||
|
||||
With over 20 million monthly downloads, LangChain has a large audience of developers building LLM applications.
|
||||
Besides just adding integrations, we also like to show them examples of cool tools or APIs they can use.
|
||||
|
||||
While traditionally called "co-marketing", we like to thing of this more as "co-education".
|
||||

|
||||
This guide walks through the process of implementing a LangChain integration
|
||||
package.
|
||||
|
||||
Integration packages are just Python packages that can be installed with `pip install <your-package>`,
|
||||
which contain classes that are compatible with LangChain's core interfaces.
|
||||
|
||||
In this guide, we will be using [Poetry](https://python-poetry.org/) for
|
||||
dependency management and packaging, and you're welcome to use any other tools you prefer.
|
||||
We will cover:
|
||||
|
||||
## **Prerequisites**
|
||||
1. (Optional) How to bootstrap a new integration package
|
||||
2. How to implement components, such as [chat models](/docs/concepts/chat_models/) and [vector stores](/docs/concepts/vectorstores/), that adhere
|
||||
to the LangChain interface;
|
||||
|
||||
## (Optional) bootstrapping a new integration package
|
||||
|
||||
In this section, we will outline 2 options for bootstrapping a new integration package,
|
||||
and you're welcome to use other tools if you prefer!
|
||||
|
||||
1. **langchain-cli**: This is a command-line tool that can be used to bootstrap a new integration package with a template for LangChain components and Poetry for dependency management.
|
||||
2. **Poetry**: This is a Python dependency management tool that can be used to bootstrap a new Python package with dependencies. You can then add LangChain components to this package.

In this guide, we will be using the `langchain-cli` to create a new integration package
|
||||
from a template, which can be edited to implement your LangChain components.

|
||||
### Boostrapping a new Python package with langchain-cli
|
||||
|
||||
First, install `langchain-cli` and `poetry`:
|
||||
|
||||
```bash
|
||||
pip install langchain-cli poetry
|
||||
```
|
||||
|
||||
Next, come up with a name for your package. For this guide, we'll use `langchain-parrot-link`.
|
||||
You can confirm that the name is available on PyPi by searching for it on the [PyPi website](https://pypi.org/).
|
||||
|
||||
Next, create your new Python package with `langchain-cli`, and navigate into the new directory with `cd`:
|
||||
|
||||
```bash
|
||||
langchain-cli integration new
|
||||
|
||||
> The name of the integration to create (e.g. `my-integration`): parrot-link
|
||||
> Name of integration in PascalCase [ParrotLink]:
|
||||
|
||||
cd parrot-link
|
||||
```
|
||||
|
||||
Next, let's add any dependencies we need
|
||||
|
||||
```bash
|
||||
poetry add my-integration-sdk
|
||||
```
|
||||
|
||||
We can also add some `typing` or `test` dependencies in a separate poetry dependency group.
|
||||
|
||||
```
|
||||
poetry add --group typing my-typing-dep
|
||||
poetry add --group test my-test-dep
|
||||
```
|
||||
|
||||
And finally, have poetry set up a virtual environment with your dependencies, as well
|
||||
as your integration package:
|
||||
|
||||
```bash
|
||||
poetry install --with lint,typing,test,test_integration
|
||||
```
|
||||
|
||||
You now have a new Python package with a template for LangChain components! This
|
||||
template comes with files for each integration type, and you're welcome to duplicate or
|
||||
delete any of these files as needed (including the associated test files).
|
||||
|
||||
To create any individual files from the [template], you can run e.g.:
|
||||
|
||||
```bash
|
||||
langchain-cli integration new \
|
||||
--name parrot-link \
|
||||
--name-class ParrotLink \
|
||||
--src integration_template/chat_models.py \
|
||||
--dst langchain_parrot_link/chat_models_2.py
|
||||

### Writing your integration
|

|
||||
## Push your package to a public Github repository
|
||||
Let's say you're building a simple integration package that provides a `ChatParrotLink`
|
||||
chat model integration for LangChain. Here's a simple example of what your project
|
||||
structure might look like:
|
||||
|
||||
```plaintext

|
||||
|
||||
All of these files should already exist from step 1, except for

||||
`chat_models.py` and `test_chat_models.py`! We will implement `test_chat_models.py`
|
||||
later, following the [standard tests](../standard_tests) guide.

## Implementing LangChain components
|
||||
|
||||
LangChain components are subclasses of base classes in [langchain-core](/docs/concepts/architecture/#langchain-core).
|
||||
Examples include [chat models](/docs/concepts/chat_models/),
|
||||
[vector stores](/docs/concepts/vectorstores/), [tools](/docs/concepts/tools/),
|
||||
[embedding models](/docs/concepts/embedding_models/) and [retrievers](/docs/concepts/retrievers/).
|
||||
|
||||
Your integration package will typically implement a subclass of at least one of these
|
||||
components. Expand the tabs below to see details on each.

Your vector store implementation will depend on your chosen database technology.
|

`langchain-core` includes a minimal

[in-memory vector store](https://python.langchain.com/api_reference/core/vectorstores/langchain_core.vectorstores.in_memory.InMemoryVectorStore.html)
|
||||
that we can use as a guide. You can access the code [here](https://github.com/langchain-ai/langchain/blob/master/libs/core/langchain_core/vectorstores/in_memory.py).
|
||||
|
||||
All vector stores must inherit from the [VectorStore](https://python.langchain.com/api_reference/core/vectorstores/langchain_core.vectorstores.base.VectorStore.html)
|
||||
base class. This interface consists of methods for writing, deleting and searching
|
||||
for documents in the vector store.
|
||||
|
||||
`VectorStore` supports a variety of synchronous and asynchronous search types (e.g.,
|
||||
nearest-neighbor or maximum marginal relevance), as well as interfaces for adding
|
||||
documents to the store. See the [API Reference](https://python.langchain.com/api_reference/core/vectorstores/langchain_core.vectorstores.base.VectorStore.html)
|

for all supported methods. The required methods are tabulated below:

| `embeddings` (property) | Embeddings object for vector store. |
|
||||
| `from_texts` | Instantiate vector store via adding texts. |
|
||||
|

Note that `InMemoryVectorStore` implements some optional search types, as well as

convenience methods for loading and dumping the object to a file, but this is not

||||
necessary for all implementations.

<TabItem value="tools" label="Tools">
|
||||
|
||||
Tools are used in 2 main ways:
|
||||
|
||||
1. To define an "input schema" or "args schema" to pass to a chat model's tool calling
|
||||
feature along with a text request, such that the chat model can generate a "tool call",
|
||||
or parameters to call the tool with.
|
||||
2. To take a "tool call" as generated above, and take some action and return a response
|
||||
that can be passed back to the chat model as a ToolMessage.
|
||||
|
||||
The `Tools` class must inherit from the [BaseTool](https://python.langchain.com/api_reference/core/tools/langchain_core.tools.base.BaseTool.html#langchain_core.tools.base.BaseTool) base class. This interface has 3 properties and 2 methods that should be implemented in a
|
||||
subclass.
|
||||
|
||||
| Method/Property | Description |
|
||||
|------------------------ |------------------------------------------------------|
|
||||
| `name` | Name of the tool (passed to the LLM too). |
|
||||
| `description` | Description of the tool (passed to the LLM too). |
|
||||
| `args_schema` | Define the schema for the tool's input arguments. |
|
||||
| `_run` | Run the tool with the given arguments. |
|
||||
| `_arun` | Asynchronously run the tool with the given arguments.|
|
||||
|
||||
### Properties
|
||||
|
||||
`name`, `description`, and `args_schema` are all properties that should be implemented
|
||||
in the subclass. `name` and `description` are strings that are used to identify the tool
|
||||
and provide a description of what the tool does. Both of these are passed to the LLM,
|
||||
and users may override these values depending on the LLM they are using as a form of
|
||||
"prompt engineering." Giving these a concise and LLM-usable name and description is
|
||||
important for the initial user experience of the tool.
|
||||
|
||||
`args_schema` is a Pydantic `BaseModel` that defines the schema for the tool's input
|
||||
arguments. This is used to validate the input arguments to the tool, and to provide
|
||||
a schema for the LLM to fill out when calling the tool. Similar to the `name` and
|
||||
`description` of the overall Tool class, the fields' names (the variable name) and
|
||||
description (part of `Field(..., description="description")`) are passed to the LLM,
|
||||
and the values in these fields should be concise and LLM-usable.
|
||||
|
||||
### Run Methods
|
||||
|
||||
`_run` is the main method that should be implemented in the subclass. This method
|
||||
takes in the arguments from `args_schema` and runs the tool, returning a string
|
||||
response. This method is usually called in a LangGraph [`ToolNode`](https://langchain-ai.github.io/langgraph/how-tos/tool-calling/), and can also be called in a legacy
|
||||
`langchain.agents.AgentExecutor`.
|
||||
|
||||
`_arun` is optional because by default, `_run` will be run in an async executor.
|
||||
However, if your tool is calling any apis or doing any async work, you should implement
|
||||
this method to run the tool asynchronously in addition to `_run`.
|
||||
|
||||
### Implementation
|
||||
|
||||
You can start from the following template or langchain-cli command:
|
||||
|
||||
```bash
|
||||
langchain-cli integration new \
|
||||
--name parrot-link \

<TabItem value="retrievers" label="Retrievers">
|
||||
|
||||
Retrievers are used to retrieve documents from APIs, databases, or other sources
|
||||
based on a query. The `Retriever` class must inherit from the [BaseRetriever](https://python.langchain.com/api_reference/core/retrievers/langchain_core.retrievers.BaseRetriever.html) base class. This interface has 1 attribute and 2 methods that should be implemented in a subclass.
|
||||
|
||||
| Method/Property | Description |
|
||||
|------------------------ |------------------------------------------------------|
|
||||
| `k` | Default number of documents to retrieve (configurable). |
|
||||
| `_get_relevant_documents`| Retrieve documents based on a query. |
|
||||
| `_aget_relevant_documents`| Asynchronously retrieve documents based on a query. |
|
||||
|
||||
### Attributes
|
||||
|
||||
`k` is an attribute that should be implemented in the subclass. This attribute
|
||||
can simply be defined at the top of the class with a default value like
|
||||
`k: int = 5`. This attribute is the default number of documents to retrieve
|
||||
from the retriever, and can be overridden by the user when constructing or calling
|
||||
the retriever.
|
||||
|
||||
### Methods
|
||||
|
||||
`_get_relevant_documents` is the main method that should be implemented in the subclass.
|
||||
|
||||
This method takes in a query and returns a list of `Document` objects, which have 2
|
||||
main properties:
|
||||
|
||||
- `page_content` - the text content of the document
|
||||
- `metadata` - a dictionary of metadata about the document
|
||||
|
||||
Retrievers are typically directly invoked by a user, e.g. as
|
||||
`MyRetriever(k=4).invoke("query")`, which will automatically call `_get_relevant_documents`
|
||||
under the hood.
|
||||
|
||||
`_aget_relevant_documents` is optional because by default, `_get_relevant_documents` will
|
||||
be run in an async executor. However, if your retriever is calling any apis or doing
|
||||
any async work, you should implement this method to run the retriever asynchronously
|
||||
in addition to `_get_relevant_documents` for performance reasons.
|
||||
|
||||
### Implementation
|
||||
|
||||
You can start from the following template or langchain-cli command:
|
||||

# How to add standard tests to an integration
|
||||
|
||||
When creating either a custom class for yourself or to publish in a LangChain integration, it is important to add standard tests to ensure it works as expected. This guide will show you how to add standard tests to each integration type.

- `langchain-core` will define the interfaces we want to import to define our custom tool.
|
||||
- `langchain-tests` will provide the standard tests we want to use, as well as pytest plugins necessary to run them. Recommended to pin to the latest version: <img src="https://img.shields.io/pypi/v/langchain-tests" style={{position:"relative",top:4,left:3}} />
|
||||
|

:::note
|

|
||||
Because added tests in new versions of `langchain-tests` can break your CI/CD pipelines, we recommend pinning the
|

version of `langchain-tests` to avoid unexpected changes.

## Add and configure standard tests
|
||||
|
||||
There are 2 namespaces in the `langchain-tests` package:
|
||||
|
||||
- [unit tests](../../../concepts/testing.mdx#unit-tests) (`langchain_tests.unit_tests`): designed to be used to test the component in isolation and without access to external services
|
||||
- [integration tests](../../../concepts/testing.mdx#integration-tests) (`langchain_tests.integration_tests`): designed to be used to test the component with access to external services (in particular, the external service that the component is designed to interact with).
|
||||
|
||||
Both types of tests are implemented as [`pytest` class-based test suites](https://docs.pytest.org/en/7.1.x/getting-started.html#group-multiple-tests-in-a-class).
|
||||
|
||||
By subclassing the base classes for each type of standard test (see below), you get all of the standard tests for that type, and you
|
||||
can override the properties that the test suite uses to configure the tests.
|
||||
|
||||
In order to run the tests in the same way as this guide, we recommend subclassing these
|
||||
classes in test files under two test subdirectories:
|
||||
|
||||
- `tests/unit_tests` for unit tests
|
||||
- `tests/integration_tests` for integration tests
|
||||
|
||||
### Implementing standard tests
|
||||
|
||||
import CodeBlock from '@theme/CodeBlock';
|
||||
|
||||
In the following tabs, we show how to implement the standard tests for
|
||||
each component type:
|
||||
|
||||
<Tabs>
|
||||
|
||||
<TabItem value="chat_models" label="Chat models">
|
||||
|
||||
To configure standard tests for a chat model, we subclass `ChatModelUnitTests` and `ChatModelIntegrationTests`. On each subclass, we override the following `@property` methods to specify the chat model to be tested and the chat model's configuration:
|
||||
|
||||
| Property | Description |
|
||||
| --- | --- |
|
||||
| `chat_model_class` | The class for the chat model to be tested |
|
||||
| `chat_model_params` | The parameters to pass to the chat
|
||||
model's constructor |
|
||||
|
||||
Additionally, chat model standard tests test a range of behaviors, from the most basic requirements (generating a response to a query) to optional capabilities like multi-modal support and tool-calling. For a test run to be successful:
|
||||
|
||||
1. If a feature is intended to be supported by the model, it should pass;
|
||||
2. If a feature is not intended to be supported by the model, it should be skipped.
|
||||
|
||||
Tests for "optional" capabilities are controlled via a set of properties that can be overridden on the test model subclass.
|
||||
|
||||
You can see the **entire list of configurable capabilities** in the API references for
|
||||
[unit tests](https://python.langchain.com/api_reference/standard_tests/unit_tests/langchain_tests.unit_tests.chat_models.ChatModelUnitTests.html)
|
||||
and [integration tests](https://python.langchain.com/api_reference/standard_tests/integration_tests/langchain_tests.integration_tests.chat_models.ChatModelIntegrationTests.html).
|
||||
|
||||
For example, to enable integration tests for image inputs, we can implement
|
||||
|
||||
```python
|
||||
@property
|
||||
def supports_image_inputs(self) -> bool:
|
||||
return True
|
||||
```
|
||||
|
||||
on the integration test class.

Here's how you would configure the standard tests for a typical vector store (using
|
||||
`ParrotVectorStore` as a placeholder):
|
||||
|
||||
Vector store tests do not have optional capabilities to be configured at this time.
|
||||
|
||||
import VectorStoreIntegrationSource from '../../../../src/theme/integration_template/tests/integration_tests/test_vectorstores.py';
|
||||
|

<CodeBlock language="python" title="tests/integration_tests/test_vectorstores.py">

VectorStoreIntegrationSource.replaceAll('__ModuleName__', 'Parrot')

.replaceAll('__module_name__', 'langchain_parrot_link')
|
||||
}
|
||||
</CodeBlock>
|
||||
|
||||
Configuring the tests consists of implementing pytest fixtures for setting up an
|
||||
empty vector store and tearing down the vector store after the test run ends.
|
||||
|
||||
| Fixture | Description |
|
||||
| --- | --- |
|
||||
| `vectorstore` | A generator that yields an empty vector store for unit tests. The vector store is cleaned up after the test run ends. |
|
||||
|
||||
For example, below is the `VectorStoreIntegrationTests` class for the [Chroma](https://python.langchain.com/docs/integrations/vectorstores/chroma/)
|
||||
integration:
|
||||
|
||||
```python
|
||||
from typing import Generator
|
||||
|
||||
import pytest
|
||||
from langchain_core.vectorstores import VectorStore
|
||||
from langchain_tests.integration_tests.vectorstores import VectorStoreIntegrationTests
|
||||
|
||||
from langchain_chroma import Chroma
|
||||
|
||||
|
||||
class TestChromaStandard(VectorStoreIntegrationTests):
|
||||
@pytest.fixture()
|
||||
def vectorstore(self) -> Generator[VectorStore, None, None]: # type: ignore
|
||||
"""Get an empty vectorstore for unit tests."""
|
||||
store = Chroma(embedding_function=self.get_embeddings())
|
||||
try:
|
||||
yield store
|
||||
finally:
|
||||
store.delete_collection()
|
||||
pass
|
||||
|
||||
```
|
||||
|
||||
Note that before the initial `yield`, we instantiate the vector store with an
|
||||
[embeddings](/docs/concepts/embedding_models/) object. This is a pre-defined
|
||||
["fake" embeddings model](https://python.langchain.com/api_reference/standard_tests/integration_tests/langchain_tests.integration_tests.vectorstores.VectorStoreIntegrationTests.html#langchain_tests.integration_tests.vectorstores.VectorStoreIntegrationTests.get_embeddings)
|
||||
that will generate short, arbitrary vectors for documents. You can use a different
|
||||
embeddings object if desired.
|
||||
|
||||
In the `finally` block, we call whatever integration-specific logic is needed to
|
||||
bring the vector store to a clean state. This logic is executed in between each test
|
||||
(e.g., even if tests fail).

||||

"There can be quite a bit of structural variation from one HTML document to another, and while `HTMLHeaderTextSplitter` will attempt to attach all \"relevant\" headers to any given chunk, it can sometimes miss certain headers. For example, the algorithm assumes an informational hierarchy in which headers are always at nodes \"above\" associated text, i.e. prior siblings, ancestors, and combinations thereof. In the following news article (as of the writing of this document), the document is structured such that the text of the top-level headline, while tagged \"h1\", is in a *distinct* subtree from the text elements that we'd expect it to be *\"above\"*—so we can observe that the \"h1\" element and its associated text do not show up in the chunk metadata (but, where applicable, we do see \"h2\" and its associated text): \n"

"## Description and motivation\n",

"Similar in concept to the [HTMLHeaderTextSplitter](/docs/how_to/HTML_header_metadata_splitter), the `HTMLSectionSplitter` is a \"structure-aware\" [text splitter](/docs/concepts/text_splitters/) that splits text at the element level and adds metadata for each header \"relevant\" to any given chunk.\n",
|
||||
"\n",
|
||||
"It can return chunks element by element or combine elements with the same metadata, with the objectives of (a) keeping related text grouped (more or less) semantically and (b) preserving context-rich information encoded in document structures.\n",
|
||||
"\n",
|
||||
"Use `xslt_path` to provide an absolute path to transform the HTML so that it can detect sections based on provided tags. The default is to use the `converting_to_header.xslt` file in the `data_connection/document_transformers` directory. This is for converting the html to a format/layout that is easier to detect sections. For example, `span` based on their font size can be converted to header tags to be detected as a section.\n",

In the following news article (as of the writing of this document), the document is structured such that the text of the top-level headline, while tagged \"h1\", is in a *distinct* subtree from the text elements that we'd expect it to be *\"above\"*—so we can observe that the \"h1\" element and its associated text do not show up in the chunk metadata (but, where applicable, we do see \"h2\" and its associated text): \n"

"\n",

"The `HTMLSemanticPreservingSplitter` is designed to split HTML content into manageable chunks while preserving the semantic structure of important elements like tables, lists, and other HTML components. This ensures that such elements are not split across chunks, causing loss of contextual relevancy such as table headers, list headers etc.\n",

"\n",
|
||||
"The `HTMLSemanticPreservingSplitter` is essential for splitting HTML content that includes structured elements like tables and lists, especially when it's critical to preserve these elements intact. Additionally, its ability to define custom handlers for specific HTML tags makes it a versatile tool for processing complex HTML documents.\n",
|
||||
"\n",
|
||||
"**IMPORTANT**: `max_chunk_size` is not a definite maximum size of a chunk, the calculation of max size, occurs when the preserved content is not apart of the chunk, to ensure it is not split. When we add the preserved data back in to the chunk, there is a chance the chunk size will exceed the `max_chunk_size`.
