Ginkgo is a testing framework for Go designed to help you write expressive tests.
https://github.com/onsi/ginkgo
MIT-Licensed

The godoc documentation outlines Ginkgo's API.  Since Ginkgo is a Domain-Specific Language it is important to
build a mental model for Ginkgo - the narrative documentation at https://onsi.github.io/ginkgo/ is designed to help you do that.
You should start there - even a brief skim will be helpful.  At minimum you should skim through the https://onsi.github.io/ginkgo/#getting-started chapter.

Ginkgo's is best paired with the Gomega matcher library: https://github.com/onsi/gomega

You can run Ginkgo specs with go test - however we recommend using the ginkgo cli.  It enables functionality
that go test does not (especially running suites in parallel).  You can learn more at https://onsi.github.io/ginkgo/#ginkgo-cli-overview
or by running 'ginkgo help'.

If, for some reason, you aren't able to do that, you can PauseOutputInterception() before starting the process

can be overridden, however, and passed into RunSpecs as optional arguments:

further assertions from running.  This panic must be recovered.  Normally, Ginkgo recovers the panic for you,
