Autocomplete

When you start typing a step, you will see auto-complete suggestions based on existing step definitions and Gherkin steps.

The suggestions are more helpful if your step definitions use Cucumber Expressions but you'll also get suggestions if they use Regular Expressions.

Go to step definition

You can quickly navigate from a Gherkin step to a step definition.

Generate step definition

Generate step definition snippets with a quick fix - ⌘ + . (MacOS) or Ctrl + . (Windows).

_IMPORTANT_: Generate step definition will only be enabled if there is at least one existing step definition. This is so that the extension can determine the programming language for the step definition, and provide choices for existing files to add it to.

Syntax highlighting

Gherkin keywords and step parameters are highlighted. Undefined steps and syntax errors are underlined.

Formatting

Gherkin documents are formatted using two space indentation.

Numeric cells are right-aligned (as in Excel). Non-numeric cells are left-aligned.

Document Outline

The Outline panel displays an outline of the Gherkin document, making it easy to navigate between scenarios.

Gherkin Localisation

Gherkin supports many translations. To specify a translation, include a # language: header in your feature file, with a supported language key from the localisation documentation.

New translations or updates are welcome and can be submitted through the gherkin parser.

Language Support

Step definitions support is provided for different languages and frameworks.

If you experience an issue with a supported language, please raise a detailed bug report or reach out for help through our Discord community.

If your language or framework is unsupported, please open an issue or raise a pull request in the Cucumber Language Service - where language support is implemented.

Feature File Icons

The Cucumber icon is applied to all feature files in your workspace. This replaces the default document icon, making it easier to identify your feature files at a glance.

Extension Settings

In most cases you shouldn't need to specify any settings as the extension comes with reasonable defaults.

If your .feature files and step definition files are in an unconventional file structure, you need to change the settings to make autocomplete work properly.

With multi-root workspaces, you will need to either specify glob paths for each workspace individually (e.g. workspace-a/features/*.feature and workspace-b/features/*.feature) or specify a glob path that matches all of them (e.g. **/features/*.feature). See VSCode documentation for configuring a multi-root workspace.

cucumber.features

The cucumber.features setting overrides where the extension should look for .feature files.

If no feature files are found, autocomplete will not work.

Default value:

cucumber.glue

The cucumber.glue setting overrides where the extension should look for source code where step definitions and parameter types are defined.

If no glue files are found, autocomplete will not work, and all Gherkin steps will be underlined as undefined. Generate step definition will not work either.

Default value:

cucumber.parameterTypes

Override the cucumber.parameterTypes setting if your Cucumber Expressions are using Custom Parameter Types that are defined outside your cucumber.glue setting.

Parameter Types in the cucumber.glue globs will be picked up automatically.

Default value:

For example, if you're using the actor parameter type from @cucumber/screenplay you'll have to declare this in the parameterTypes setting:
