+Testify - Thou Shalt Write Tests
+================================
+
+[![Build Status](https://travis-ci.org/stretchr/testify.svg)](https://travis-ci.org/stretchr/testify)
+
+Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.
+
+Features include:
+
+  * [Easy assertions](#assert-package)
+  * [Mocking](#mock-package)
+  * [HTTP response trapping](#http-package)
+  * [Testing suite interfaces and functions](#suite-package)
+
+Get started:
+
+  * Install testify with [one line of code](#installation), or [update it with another](#staying-up-to-date)
+  * For an introduction to writing test code in Go, see our [blog post article](http://blog.stretchr.com/2014/03/05/test-driven-development-specifically-in-golang/) or check out  http://golang.org/doc/code.html#Testing
+  * Check out the API Documentation http://godoc.org/github.com/stretchr/testify
+  * To make your testing life easier, check out our other project, [gorc](http://github.com/stretchr/gorc)
+  * A little about [Test-Driven Development (TDD)](http://en.wikipedia.org/wiki/Test-driven_development)
+
+
+
+[`assert`](http://godoc.org/github.com/stretchr/testify/assert "API documentation") package
+-------------------------------------------------------------------------------------------
+
+The `assert` package provides some helpful methods that allow you to write better test code in Go.
+
+  * Prints friendly, easy to read failure descriptions
+  * Allows for very readable code
+  * Optionally annotate each assertion with a message
+
+See it in action:
+
+```go
+package yours
+
+import (
+  "testing"
+  "github.com/stretchr/testify/assert"
+)
+
+func TestSomething(t *testing.T) {
+
+  // assert equality
+  assert.Equal(t, 123, 123, "they should be equal")
+
+  // assert inequality
+  assert.NotEqual(t, 123, 456, "they should not be equal")
+
+  // assert for nil (good for errors)
+  assert.Nil(t, object)
+
+  // assert for not nil (good when you expect something)
+  if assert.NotNil(t, object) {
+
+    // now we know that object isn't nil, we are safe to make
+    // further assertions without causing any errors
+    assert.Equal(t, "Something", object.Value)
+
+  }
+
+}
+```
+
+  * Every assert func takes the `testing.T` object as the first argument.  This is how it writes the errors out through the normal `go test` capabilities.
+  * Every assert func returns a bool indicating whether the assertion was successful or not, this is useful for if you want to go on making further assertions under certain conditions.
+
+if you assert many times, use the below:
+
+```go
+package yours
+
+import (
+  "testing"
+  "github.com/stretchr/testify/assert"
+)
+
+func TestSomething(t *testing.T) {
+  assert := assert.New(t)
+
+  // assert equality
+  assert.Equal(123, 123, "they should be equal")
+
+  // assert inequality
+  assert.NotEqual(123, 456, "they should not be equal")
+
+  // assert for nil (good for errors)
+  assert.Nil(object)
+
+  // assert for not nil (good when you expect something)
+  if assert.NotNil(object) {
+
+    // now we know that object isn't nil, we are safe to make
+    // further assertions without causing any errors
+    assert.Equal("Something", object.Value)
+  }
+}
+```
+
+`require` package
+-------------------------------------------------------------------------------------------
+
+The `require` package provides same global functions as the `assert` package, but instead of returning a boolean result they terminate current test.
+
+See [t.FailNow](http://golang.org/pkg/testing/#T.FailNow) for details.
+
+
+[`http`](http://godoc.org/github.com/stretchr/testify/http "API documentation") package
+---------------------------------------------------------------------------------------
+
+The `http` package contains test objects useful for testing code that relies on the `net/http` package.  Check out the [(deprecated) API documentation for the `http` package](http://godoc.org/github.com/stretchr/testify/http).
+
+We recommend you use [httptest](http://golang.org/pkg/net/http/httptest) instead.
+
+[`mock`](http://godoc.org/github.com/stretchr/testify/mock "API documentation") package
+----------------------------------------------------------------------------------------
+
+The `mock` package provides a mechanism for easily writing mock objects that can be used in place of real objects when writing test code.
+
+An example test function that tests a piece of code that relies on an external object `testObj`, can setup expectations (testify) and assert that they indeed happened:
+
+```go
+package yours
+
+import (
+  "testing"
+  "github.com/stretchr/testify/mock"
+)
+
+/*
+  Test objects
+*/
+
+// MyMockedObject is a mocked object that implements an interface
+// that describes an object that the code I am testing relies on.
+type MyMockedObject struct{
+  mock.Mock
+}
+
+// DoSomething is a method on MyMockedObject that implements some interface
+// and just records the activity, and returns what the Mock object tells it to.
+//
+// In the real object, this method would do something useful, but since this
+// is a mocked object - we're just going to stub it out.
+//
+// NOTE: This method is not being tested here, code that uses this object is.
+func (m *MyMockedObject) DoSomething(number int) (bool, error) {
+
+  args := m.Called(number)
+  return args.Bool(0), args.Error(1)
+
+}
+
+/*
+  Actual test functions
+*/
+
+// TestSomething is an example of how to use our test object to
+// make assertions about some target code we are testing.
+func TestSomething(t *testing.T) {
+
+  // create an instance of our test object
+  testObj := new(MyMockedObject)
+
+  // setup expectations
+  testObj.On("DoSomething", 123).Return(true, nil)
+
+  // call the code we are testing
+  targetFuncThatDoesSomethingWithObj(testObj)
+
+  // assert that the expectations were met
+  testObj.AssertExpectations(t)
+
+}
+```
+
+For more information on how to write mock code, check out the [API documentation for the `mock` package](http://godoc.org/github.com/stretchr/testify/mock).
+
+You can use the [mockery tool](http://github.com/vektra/mockery) to autogenerate the mock code against an interface as well, making using mocks much quicker.
+
+[`suite`](http://godoc.org/github.com/stretchr/testify/suite "API documentation") package
+-----------------------------------------------------------------------------------------
+
+The `suite` package provides functionality that you might be used to from more common object oriented languages.  With it, you can build a testing suite as a struct, build setup/teardown methods and testing methods on your struct, and run them with 'go test' as per normal.
+
+An example suite is shown below:
+
+```go
+// Basic imports
+import (
+    "testing"
+    "github.com/stretchr/testify/assert"
+    "github.com/stretchr/testify/suite"
+)
+
+// Define the suite, and absorb the built-in basic suite
+// functionality from testify - including a T() method which
+// returns the current testing context
+type ExampleTestSuite struct {
+    suite.Suite
+    VariableThatShouldStartAtFive int
+}
+
+// Make sure that VariableThatShouldStartAtFive is set to five
+// before each test
+func (suite *ExampleTestSuite) SetupTest() {
+    suite.VariableThatShouldStartAtFive = 5
+}
+
+// All methods that begin with "Test" are run as tests within a
+// suite.
+func (suite *ExampleTestSuite) TestExample() {
+    assert.Equal(suite.T(), suite.VariableThatShouldStartAtFive, 5)
+}
+
+// In order for 'go test' to run this suite, we need to create
+// a normal test function and pass our suite to suite.Run
+func TestExampleTestSuite(t *testing.T) {
+    suite.Run(t, new(ExampleTestSuite))
+}
+```
+
+For a more complete example, using all of the functionality provided by the suite package, look at our [example testing suite](https://github.com/stretchr/testify/blob/master/suite/suite_test.go)
+
+For more information on writing suites, check out the [API documentation for the `suite` package](http://godoc.org/github.com/stretchr/testify/suite).
+
+`Suite` object has assertion methods:
+
+```go
+// Basic imports
+import (
+    "testing"
+    "github.com/stretchr/testify/suite"
+)
+
+// Define the suite, and absorb the built-in basic suite
+// functionality from testify - including assertion methods.
+type ExampleTestSuite struct {
+    suite.Suite
+    VariableThatShouldStartAtFive int
+}
+
+// Make sure that VariableThatShouldStartAtFive is set to five
+// before each test
+func (suite *ExampleTestSuite) SetupTest() {
+    suite.VariableThatShouldStartAtFive = 5
+}
+
+// All methods that begin with "Test" are run as tests within a
+// suite.
+func (suite *ExampleTestSuite) TestExample() {
+    suite.Equal(suite.VariableThatShouldStartAtFive, 5)
+}
+
+// In order for 'go test' to run this suite, we need to create
+// a normal test function and pass our suite to suite.Run
+func TestExampleTestSuite(t *testing.T) {
+    suite.Run(t, new(ExampleTestSuite))
+}
+```
+

+// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
+//
+// Example Usage
+//
+// The following is a complete example using assert in a standard test function:
+//    import (
+//      "testing"
+//      "github.com/stretchr/testify/assert"
+//    )
+//
+//    func TestSomething(t *testing.T) {
+//
+//      var a string = "Hello"
+//      var b string = "Hello"
+//
+//      assert.Equal(t, a, b, "The two words should be the same.")
+//
+//    }
+//
+// if you assert many times, use the below:
+//
+//    import (
+//      "testing"
+//      "github.com/stretchr/testify/assert"
+//    )
+//
+//    func TestSomething(t *testing.T) {
+//      assert := assert.New(t)
+//
+//      var a string = "Hello"
+//      var b string = "Hello"
+//
+//      assert.Equal(a, b, "The two words should be the same.")
+//    }
+//
+// Assertions
+//
+// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
+// All assertion functions take, as the first argument, the `*testing.T` object provided by the
+// testing framework. This allows the assertion funcs to write the failings and other details to
+// the correct place.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.
+//
+// Here is an overview of the assert functions:
+//
+//    assert.Equal(t, expected, actual [, message [, format-args]])
+//
+//    assert.EqualValues(t, expected, actual [, message [, format-args]])
+//
+//    assert.NotEqual(t, notExpected, actual [, message [, format-args]])
+//
+//    assert.True(t, actualBool [, message [, format-args]])
+//
+//    assert.False(t, actualBool [, message [, format-args]])
+//
+//    assert.Nil(t, actualObject [, message [, format-args]])
+//
+//    assert.NotNil(t, actualObject [, message [, format-args]])
+//
+//    assert.Empty(t, actualObject [, message [, format-args]])
+//
+//    assert.NotEmpty(t, actualObject [, message [, format-args]])
+//
+//    assert.Len(t, actualObject, expectedLength, [, message [, format-args]])
+//
+//    assert.Error(t, errorObject [, message [, format-args]])
