For example: bundle exec cucumber -pnone features. Cucumber-Rails is a gem that Rails projects can use to install cucumber and create its configuration. Add cucumber-rails to your Gemfile : Note : you do not need to add Cucumber.
Cucumber-Rails will detect whether the RSpec gems are installed. If so, then the rails generator builds the environment files to suit. If not, it ignores RSpec and configures for test-unit instead.

This page describes tools for a Ruby or Ruby on Rails environment. Build tools Cucumber can be run in several ways.
Rake Running rake cucumber from the command line provides the simplest method to run Cucumber tests. AfterConfiguration has been deprecated in favor of BeforeAll and InstallPlugin depending on your needs. Tags that are placed above a Scenario Outline will be inherited by Examples. For JUnit 5 see the cucumber-junit-platform-engine documetation. Another way to run a subset of scenarios is to use the file. For even more advanced tag expressions you can use parenthesis for clarity, or to change operator precedence:.
Tags can refer to IDs in external systems such as requirement management tools, issue trackers or test management tools:. You can use a custom Cucumber reporting plugin that will turn tags into links pointing to documents in your external tool.
Another creative way to use tags is to keep track of where in the development process a certain feature is:. As distributed, Cucumber-Rails builds a Rake task that recognizes the wip tag. However, any string may be used as a tag and any scenario or entire feature can have multiple tags associated with it. This tells Cucumber to not process features and scenarios with this tag.
If you do not specify a different profile cucumber -p profilename , then the default profile will be used. Since version 0. The wip tags are a special case. If any scenario tagged as wip passes all of its steps without error, and the --wip option is also passed, Cucumber reports the run as failing because Scenarios that are marked as a work in progress are not supposed to pass!
Note as well that the --strict and --wip options are mutually exclusive. The number of occurrences of a particular tag in your features may be controlled by appending a colon followed by a number to the end of the tag name passed to the --tags option, like so:. The existence of more than the specified number of occurrences of that tag in all the features that are exercised during a particular Cucumber run will produce a warning message.
If the --strict option is passed as well, as is the case with the default profile, then instead of a warning the run will fail. Limiting the number of occurrences is commonly used in conjunction with the wip tag to restrict the number of unspecified scenarios to manageable levels. Those following Kanban or Lean Software Development based methodologies will find this useful. Cucumber is a Java library with extensions for different tools and platforms. Java library with extensions for different tools and platforms.
It is possible to configure how Cucumber should run features. The most common option is to run Cucumber from the command line. By default, Cucumber will treat anything ending in The most common option is to run Cucumber from the command line. By default, Cucumber will treat anything ending in. Note that if the --require option is passed, then ONLY that directory tree will be searched for step definition matches. You may specify the --require option multiple times if you need to include step definitions from directories that do not share a convenient root.
Note that you will need to add the cucumber-core jar and all of its transitive dependencies to your classpath, in addition to the location of your compiled. You can find these jars in Maven Central. You will also need to provide the CLI with your step definitions via the --glue option followed by its package name, and the filepath of your feature file s.
After installing Cucumber in a project, you can run it with:. Use cucumber-js or cucumberjs instead of cucumber. The latter is causing the operating system to invoke JScript instead of Node. Cucumber does not work when installed globally because cucumber needs to be required in support files and globally installed modules cannot be required.
You can also run features using a build tool or an IDE. See the cucumber-junit-platform-engine documentation. To use JUnit to execute cucumber scenarios add the cucumber-junit dependency to your pom. Note that cucumber-junit is based on JUnit 4.
Or include junit-vintage-engine dependency, as well. For more information, please refer to JUnit 5 documentation. This will execute all scenarios in same package as the runner, by default glue code is also assumed to be in the same package.
The CucumberOptions can be used to provide additional configuration to the runner. For example if you want to tell Cucumber to use the two formatter plugins pretty and html , you can specify it like this:. For example if you want to tell Cucumber to print code snippets for missing step definitions use the summary plugin, you can specify it like this:.
This settings can be used to specify the way code snippets will be created by Cucumber. For example if you want to check whether all feature file steps have corresponding step definitions, you can specify it like this:. For example if you want console output from Cucumber in a readable format, you can specify it like this:. For example if you want to tell Cucumber to only run the scenarios specified with specific tags, you can specify it like this:.
For example if you are using Cucumber with a DI framework and want to use a custom object factory, you can specify it like this:. The default option for objectFactory is to use the default object factory.
Additional information about using custom object factories can be found here. These will executed before and after all scenarios. Using these is not recommended, as it limits the portability between different runners; they may not execute correctly when using the commandline, IntelliJ IDEA or Cucumber-Eclipse.
