This test runs a fake Ginkgo suite with various errors and checks how
logger.go respectively ginkgowrapper.go handle this. Right now, the
outcome is sub-optimal:
- some test failures (those that use framework.Failf or
framework.ExpectNoError) are logged immediately, Gomega failures
are not
- framework.ExpectNoError logs just the error, which is often useless
without the additional explanation
- failures that occur after some others are not reported at all;
this can happen in cleanup code and while that code should better
be written so that it contines instead of failing on an assertion,
in practice quite a lot of code fails and when it does, the output
would be useful to have
- the full stack trace is odd and doesn't start with the expected
function name
Example output:
• Failure [0.002 seconds]

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
go get -d k8s.io/kubernetes
cd $GOPATH/src/k8s.io/kubernetes
make
You have a working Docker environment.
git clone https://github.com/kubernetes/kubernetes
cd kubernetes
make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
