Features

Codelens

A Karate: Run and Karate: Debug Codelens will be added above each Feature:, Scenario: and Scenario Outline: within each feature file. Clicking on a Feature Codelens will run/debug all Scenario and Scenario Outlines within its feature file. Clicking on a Scenario or Scenario Outline Codelens will run/debug only that Scenario or Scenario Outline.

Codelens will additionally be shown when hovering over any row within an Examples: table for a Scenario Outline:. Clicking here will run/debug only the currently hovered over row.

Activity Bar

A Karate Activity Bar will be added to VSCode. Clicking on the Activity Bar will reveal Reports and Tests views. Both views can be displayed as a Flat list or Tree structure. The Tests view can additionally be displayed in an aggregated Tags view. Clicking on a report within the Reports view will open it within the default program defined for its file type. Clicking on a test within the Tests view will open it for viewing within the VSCode Editor. Hovering over any node within the Tests view will provide a list of actions/buttons that can be clicked to run/debug/view tests.

Note: Clicking Run All Tests will run all tests applicable to the given node type (Tag, Folder, File, Feature) in the Tests view regardless of the currently set filter. This is especially applicable when filtering by tag.

Note: Tests annotated with the @ignore tag will be shown as ignored in the Tests view and will not be run.

Debugger

Karate Debug Configurations will be added to Debug/Run Activity Bar. See Setup > Debugger section below for setup details. Starting the debugger after setup will enable you to use all debug controls to step through and debug your feature files.

Smart Paste

A Smart Paste option will be added to detect paste operations into feature files. If a curl command is detected it will be transformed into Karate syntax and pasted into the VSCode Editor.

Status Bar

A Karate Status Bar will be added to VSCode showing results for the last execution as well as the currently defined karate.env at setting Karate Runner › Core: Environment. The Karate Status Bar background will additionally be colored red when the last execution's failure percentage exceeds the defined threshold in Karate Runner settings. Clicking Karate Status Bar will reveal historical results executed from Codelens or Karate Activity Bar. Clicking historical results will re-execute the command which produced those results.

Note this feature is dependent on Karate providing a results file under the root of your project. For Karate Version < 1.0 a file called results-json.txt For Karate Version >= 1.0 a file called karate-summary-json.txt

Test Results (Karate 1.0 or greater)

Test Results will be shown for each Feature:, Scenario:, Scenario Outline: and parent folder in the Tests view. And will be shown for each Feature:, Scenario:, Scenario Outline: within each Feature file.

Test Results will be represented in three ways. By a Karate icon with a green dot (pass) or red dot (fail), with failure details on hover and finally a failure count showing how many failures are below each folder or file in the Tests view.

Failure details shown on hover will consist of a stack trace showing line-by-line execution. Each line will consist of an arrow showing execution direction and depth, the Karate code executed and a link to the file with the code that can be hovered over to show the error message and any arguments or clicked on to open the file. Finally a red dot will be shown on each line if it is the last line in the call chain to show the likely root cause of the failure.

Test Results are rolling results meaning they will accumulate and reset only when you click Clear Results.

Note this feature is dependent on Karate Version >= 1.0 and Karate providing result files under the root of your project within a /karate-reports directory. Each file must end with a format of .karate-json.txt.

Editor Menu Bar

A Karate Editor Menu will be added to the VSCode Editor Menu Bar for open feature files. The menu will have the following options:

• Align Data Tables to align delimiters (|) for all gherkin data tables
• Clear Results to clear test results from the gutter including from the Tests view
• Open Settings to open Karate Runner settings
• Toggle Results In Gutter to toggle showing or hiding test results within the gutter

Peek

A Peek option will be added to the Control-Click or Right-Click context menu in the VSCode Editor. Clicking Peek > Peek Definition on a string or reference (or any combination of if concat'd) which equates to an existing file will display the contents of that file within an Inline Peek Editor.

Note if the path being peeked starts with classpath: this extension will search recursively within the target project to find the file, searching first within <project root>/src/test, followed by <project root>/src and ending with <project root>/

Key Bindings

Key Bindings will be added to enable running Karate tests and Smart Paste from the keyboard.

Smart Paste

• Requirement: Open any file in VSCode Editor and ensure editor has focus.
• Windows: Ctrl+V
• Linux: Ctrl+Shift+V
• Mac: Cmd+V

Run Karate Test

• Requirement: Open a feature file in VSCode Editor and ensure a line associated with a test has cursor focus.
• Windows: Ctrl+R+1
• Linux: Ctrl+Shift+R+1
• Mac: Cmd+R+1

Run All Karate Tests

• Requirement: Open a feature file in VSCode Editor and ensure editor has focus.
• Windows: Ctrl+R+A
• Linux: Ctrl+Shift+R+A
• Mac: Cmd+R+A

Note key bindings can be changed if desired by going to Menu > Preferences > Keyboard Shortcuts

Syntax Highlighting

Syntax Highlighting will be added to enable bracket pairing and coloring for the Karate language within .feature files. Additionally coloring will be enhanced within .js files to support Karate language integration.

Note this is a work in progress as the Karate Language and VSCode Themes evolve.

Intellisense

Intellisense will be added to the Karate read() command to enumerate all files in the same directory. Additionally if <project root>/src/test/java, <project root>/src/test/resources exist, all files within those directories will be enumerated. Finally entering @ after the selected file will enumerate all tags within the file.

Note suggested auto completion text from extensions like Github Copilot can interfere with this feature. This can typically be resolved by pressing the Escape key to clear the suggested text.

Setup

Versions

• VSCode Version 1.83.0 or greater. (Required)
• Karate Version 0.9.3 or greater in your Karate projects. (Required)
• Karate Version 0.9.5 or greater in your Karate projects. (Required for Debugger or Karate Cli)
• Karate Version 1.0.0 or greater in your Karate projects. (Required for Tests View results)

This Extension

• Goto the following path to configure all workspace settings for this extension Preferences > Settings > Search for Karate Runner or click the gear icon in the header of the Tests View.

Execution

• Ensure an execution option (karate.jar, pom.xml (Maven), build.gradle (Gradle Groovy), build.gradle.kts (Gradle Kotlin), package.json (NPM, Yarn, etc)) exists at the root of your project.
• This extension will detect which execution option exists at your project root and execute the appropriate command.
• Note if an execution option is not specified this extension will still attempt to run the command provided at Karate Runner › Karate Jar: Command Line Args. This can be useful if you are using facilities such as JBang.
• Note if multiple execution options exist karate.jar will be favored and used first, followed by pom.xml (Maven), then build.gradle (Gradle Groovy), then build.gradle.kts (Gradle Kotlin) and lastly package.json (NPM, Yarn, etc).

Note Javascript package managers such as NPM, Yarn, etc are only supported on Mac and Linux at this time as there is currently an outstanding bug in Karate wherein Windows file paths are not supported.
