Ginkgo: A Go BDD Testing Framework

Build Status

Jump to the docs to learn more. To start rolling your Ginkgo tests now keep reading!

If you have a question, comment, bug report, feature request, etc. please open a GitHub issue.

Feature List

  • Ginkgo uses Go's testing package and can live alongside your existing testing tests. It's easy to bootstrap and start writing your first tests

  • Structure your BDD-style tests expressively:

  • A comprehensive test runner that lets you:

    • Mark specs as pending
    • Focus individual specs, and groups of specs, either programmatically or on the command line
    • Run your tests in random order, and then reuse random seeds to replicate the same order.
    • Break up your test suite into parallel processes for straightforward test parallelization
  • ginkgo: a command line interface with plenty of handy command line arguments for running your tests and generating test files. Here are a few choice examples:

    • ginkgo -nodes=N runs your tests in N parallel processes and print out coherent output in realtime
    • ginkgo -cover runs your tests using Go's code coverage tool
    • ginkgo convert converts an XUnit-style testing package to a Ginkgo-style package
    • ginkgo -focus="REGEXP" and ginkgo -skip="REGEXP" allow you to specify a subset of tests to run via regular expression
    • ginkgo -r runs all tests suites under the current directory
    • ginkgo -v prints out identifying information for each tests just before it runs

    And much more: run ginkgo help for details!

    The ginkgo CLI is convenient, but purely optional -- Ginkgo works just fine with go test

  • ginkgo watch watches packages and their dependencies for changes, then reruns tests. Run tests immediately as you develop!

  • Built-in support for testing asynchronicity

  • Built-in support for benchmarking your code. Control the number of benchmark samples as you gather runtimes and other, arbitrary, bits of numerical information about your code.

  • Completions for Sublime Text: just use Package Control to install Ginkgo Completions.

  • Completions for VSCode: just use VSCode's extension installer to install vscode-ginkgo.

  • Straightforward support for third-party testing libraries such as Gomock and Testify. Check out the docs for details.

  • A modular architecture that lets you easily:

Gomega: Ginkgo's Preferred Matcher Library

Ginkgo is best paired with Gomega. Learn more about Gomega here

Agouti: A Go Acceptance Testing Framework

Agouti allows you run WebDriver integration tests. Learn more about Agouti here

Set Me Up!

You'll need the Go command-line tools. Ginkgo is tested with Go 1.6+, but preferably you should get the latest. Follow the installation instructions if you don't have it installed.

go get -u github.com/onsi/ginkgo/ginkgo  # installs the ginkgo CLI
go get -u github.com/onsi/gomega/...     # fetches the matcher library

cd path/to/package/you/want/to/test

ginkgo bootstrap # set up a new ginkgo suite
ginkgo generate  # will create a sample test file.  edit this file and add your tests then...

go test # to run your tests

ginkgo  # also runs your tests

I'm new to Go: What are my testing options?

Of course, I heartily recommend Ginkgo and Gomega. Both packages are seeing heavy, daily, production use on a number of projects and boast a mature and comprehensive feature-set.

With that said, it's great to know what your options are :)

What Go gives you out of the box

Testing is a first class citizen in Go, however Go's built-in testing primitives are somewhat limited: The testing package provides basic XUnit style tests and no assertion library.

Matcher libraries for Go's XUnit style tests

A number of matcher libraries have been written to augment Go's built-in XUnit style tests. Here are two that have gained traction:

You can also use Ginkgo's matcher library Gomega in XUnit style tests

BDD style testing frameworks

There are a handful of BDD-style testing frameworks written for Go. Here are a few:

Finally, @shageman has put together a comprehensive comparison of Go testing libraries.
