Cucumber.js

1. To work with Cucumber.js versions 6.0.0+, make sure you are using GoLand 2020.3.1 or later.

2. Download and install Node.js.

3. Make sure the JavaScript and TypeScript plugin is enabled in the settings. Press Control+Alt+S to open the IDE settings and then select Plugins. Click the Installed tab. In the search field, type JavaScript and TypeScript. For more details about plugins, see Managing plugins.

4. Install the Cucumber.js and Gherkin plugins on the Settings | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains Marketplace.

• In the embedded Terminal (Alt+F12) , type one of the following commands:

  • npm install cucumber for local installation in your project.

  • npm install -g cucumber for global installation.

  • npm install --save-dev cucumber to install Cucumber.js as a development dependency.

  See also Cucumber.js demo on the Cucumber.js official website.

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

   

   Alternatively, hover the mouse over the step and use the links in the popup.

   

2. In the dialog that opens, specify the name for the new file and the language to write the definitions in.

   

   If such file already exists, GoLand displays a popup where you have to select a file to add the definition to or choose to create a new file.

   

Create a Cucumber.js run configuration

1. Open the Run/Debug Configuration dialog (Run | Edit Configurations on the main menu), click in the left-hand pane, and select Cucumber.js from the list. The Run/Debug Configuration: Cucumber.js dialog opens.

2. In the Feature file or directory field, specify the tests to run. Type the path to a specific .feature file or to a folder, if you want to run a bunch of features.

3. Specify the Node.js interpreter to use.

   If you choose the Project alias, GoLand will automatically use the project default interpreter from the Node interpreter field . In most cases, GoLand detects the project default interpreter and fills in the field itself.

   You can also choose another configured local interpreter or click and configure a new one.

4. In the Cucumber package field, specify the path to the folder where the cucumber package is stored.

5. Specify the working directory of the application. By default, the Working directory field shows the project root folder. To change this predefined setting, specify the path to the desired folder.

6. Optionally:

   • In the Name Filter field, type the name of a specific scenario to run instead of all the scenarios from the feature file or directory.

   • Specify the command-line arguments to be passed to the executable file, such as -r --require LIBRARY|DIR, -t --tags TAG_EXPRESSION, or --coffee. For details, see native built-in help available through the cucumber-js --help command.

   • In the Environment variables field, specify the environment variables for your application.

Run tests via a run configuration

1. Select the Cucumber.js run/debug configuration from the list of configurations and click   in the list or on the toolbar.

2. Monitor test execution and analyze test results in the Test Runner tab of the Run tool window, see Explore test results for details.

Run tests from a test file

• To run a single test, open the test file in the editor, position the caret at the scenario to run, and then select Run Scenario: <scenario name> from the context menu.

• To run all tests from a single test file, open the test file in the editor or select it in the Project tool window and choose Run <test filename> from the context menu.

In either case, GoLand creates a run/debug configuration which you can save and use later.

• To jump between a test and its subject or vice versa, open the file in the editor and select Go to | Test or Go to | Test Subject from the context menu, or just press Control+Shift+T.

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

  

• To jump from a test result to the test definition, click the test name in the Test Runner tab twice, or select Jump to Source from the context menu, or just press F4. The test file opens in the editor with the cursor placed at the test definition.

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

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