Cucumber is a tool for running automated acceptance tests, written in plain language. Because they're written in plain language, they can be read by anyone on your team. Because they can be read by anyone, they help improve communication, collaboration and trust on your team. 💖

Cucumber was built to support Behaviour-Driven Development (BDD).

If you want to get started using Cucumber, you should head over to the docs or watch our Cucumber School video series.

Cucumber is open source, built and maintained by people just like you! All of the source code for Cucumber is under this GitHub organization.

Everyone interacting in these codebases and issue trackers is expected to follow the Cucumber Community Code of Conduct.

If you have questions about using Cucumber, or ideas for how we could improve it, head over to our GitHub Discussions forum. If you want chat with the maintainers, the best place for that is to join the Community Discord.

If you've found a bug in Cucumber, or have an idea for a new feature, you can raise an issue on GitHub.

We currently support four official versions of Cucumber:

• Cucumber-Ruby
• Cucumber-JVM
• Cucumber-JS
• GoDog for Go

Other popular Cucumber implementations, maintained by other organisations, are:

• Reqnroll for C#
• Behave for Python
• Cucumber Rust
• Behat for PHP

If you're not sure where to raise your issue, you can use our common repository, or come and chat with us in the Community Discord.

The Cucumber team is committed to tackling the structural racism and sexism in open source, and providing a fun and welcoming environment for new contributors.

Contributions don't have to be code. If you think you'd like to help, book some time with our project lead @mattwynne and have a chat about what you're interested in. We can find something useful for you to do!
