Cucumber is a tool for running automated 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, you can use them to help improve communication, collaboration and trust on
your team.
This is the Ruby implementation of Cucumber. Cucumber is also available for [JavaScript](https://github.com/cucumber/cucumber-js),
[Java](https://github.com/cucumber/cucumber-jvm), and a lot of other languages. You can find a list of implementations here: https://cucumber.io/docs/installation/.
See [CONTRIBUTING.md](CONTRIBUTING.md) for info on contributing to Cucumber (issues, PRs, etc.).
Everyone interacting in this codebase and issue tracker is expected to follow the
Cucumber [code of conduct](https://cucumber.io/conduct).
## Installation
Cucumber for Ruby is a Ruby gem. Install it as you would install any gem: add
`cucumber` to your Gemfile:
gem 'cucumber'
then install it:
$ bundle
or install the gem directly:
$ gem install cucumber
Later in this document, bundler is considered being used so all commands are using
`bundle exec`. If this is not the case for you, execute `cucumber` directly, without
`bundle exec`.
### Supported platforms
- Ruby 3.2
- Ruby 3.1
- Ruby 3.0
- Ruby 2.7
- TruffleRuby 22.0.0+
- JRuby 9.4+ (with [some limitations](https://github.com/cucumber/cucumber-ruby/blob/main/docs/jruby-limitations.md))
### Ruby on Rails
Using Ruby on Rails? You can use [cucumber-rails](https://github.com/cucumber/cucumber-rails) to bring Cucumber into your Rails project.
## Usage
### Initialization
If you need to, initialize your `features` directory with
$ bundle exec cucumber --init
This will create the following directories and files if they do not exist already:
features
├── step_definitions
└── support
└── env.rb
### Create your specification
Create a file named `rule.feature` in the `features` directory with:
```gherkin
# features/rule.feature
Feature: Rule Sample
Rule: This is a rule
Example: A passing example
Given this will pass
When I do an action
Then some results should be there
Example: A failing example
Given this will fail
When I do an action
Then some results should be there
```
### Automate your specification
And a file named `steps.rb` in `features/step_definitions` with:
```ruby
# features/step_definitions/steps.rb
Given('this will pass') do
@this_will_pass = true
end
Given('this will fail') do
@this_will_pass = false
end
When('I do an action') do
:no_op
end
Then("some results should be there") do
expect(@this_will_pass).to be true
end
```
### Run Cucumber
$ bundle exec cucumber
To execute a single feature file:
$ bundle exec cucumber features/rule.feature
To execute a single example, indicates the line of the name of the example:
$ bundle exec cucumber features/rule.feature:5
To summarize the results on the standard output, and generate a HTML report on disk:
$ bundle exec cucumber --format summary --format html --out report.html
For more command line options
$ bundle exec cucumber --help
You can also find documentation on the command line possibilities in [features/docs/cli](features/docs/cli).
