Cucumber

1. Add the 'cucumber-rails' gem to the test group of the project's Gemfile and install it.

2. From the main menu, select Tools | Run Rails Generator Ctrl+Alt+G and start typing cucumber:install. Select the corresponding command from the list and press Enter.

   

3. In the Setup Cucumber Support dialog, choose the test framework for Cucumber, specify the required options, and click OK.

   

   RubyMine will run the cucumber:install generator that sets up Cucumber in your Rails project and generates necessary files in the features directory. After running this generator, you will also get a new Rake task called cucumber that can be used to run Cucumber tests in RubyMine.

1. In the Project tool window, right-click a directory, where feature files should be created.

2. From the context menu of this directory, choose New | File Alt+Insert, and create a file with the .feature extension.

   

3. In the created feature file, type your scenario. For example, we'll use a code snippet from the Cucumber Getting Started:

   Feature: Is it Friday yet?
     Everybody wants to know when it's Friday
   
   Scenario: Sunday isn't Friday
     Given today is Sunday
     When I ask whether it's Friday yet
     Then I should be told "Nope"

   Since there are no step definitions, the steps will be highlighted as unresolved. See the next chapter to learn how to create step definitions.

1. Place the caret at the step without a definition, press Alt+Enter, and select Create step definition or Create all step definitions.

   

2. Choose whether to use the existing step definition file or create a new one.

   

   Press Enter.

3. (Optional) If you selected Create new file, specify the name for the new file and the language for writing definitions.

   

   Click OK.

4. In the opened Ruby file, write step definition code.

   

1. Press Ctrl+Shift+A and start typing edit configurations. Select Edit Configurations and press Enter.

   

2. In the opened Run/Debug Configurations dialog, select the required configuration, and specify its settings.

   

   For example, you can specify the following settings:

   Option	Description
   Mode	Choose whether to run all features in a directory or file.
   Features folder / Feature file	Specify the full path to the folder/file that contains the desired features.
   Element name filter	Allows you to run only scenarios that match a certain name. This can be a substring of the names of Features, Scenarios, Scenario Outlines, or Example blocks. Learn more at Cucumber help.
   Tags filter	Specify tags to run subsets of features. Learn more at Tag logic.
   Runner options	Specify the required options for running Cucumber tests. For example, the -r features parameter loads files from the features folder before running tests.
   'Cucumber' gem	Select the Cucumber gem used to run tests.
   Use custom Cucumber runner script	Enable this option if you want to use an alternative Cucumber runner script. You can type the full path to the Cucumber runner script in the text field, or click , and select the desired runner script in the dialog that opens.

   Click OK to save the run/debug configuration.

3. To run the saved configuration, press Ctrl twice, start typing the configuration name, select it from the list, and press Enter.

   

Convert Scenario to Outline

1. Place the caret at the desired scenario and press Alt+Enter.

2. Select Convert scenario to outline and press Enter.

   

   RubyMine will change Scenario to Scenario Outline and add the Examples table.

   

Create Examples in Scenario Outline

RubyMine provides an inspection to detect examples missing in scenario outlines. To create missing examples, do the following:

1. Place the caret at the highlighted scenario outline and press Alt+Enter.

2. Select Create Examples Section and press Enter.

   

   RubyMine will create the Examples table with a header row.

• To jump from a step in a .feature file to the step definition, press and hold Ctrl, hover over the step, and click the step when it turns into a link.

1. In the Settings/Preferences dialog (Ctrl+Alt+S), go to Editor | Color Scheme | Cucumber.

2. Select the color scheme, accept the highlighting settings inherited from defaults or customize them as described in Configuring Colors and Fonts.
