• @vscode/test-electron: This package provides the necessary utilities for running tests on VSCode extensions.
• mocha: A widely used JavaScript test framework that provides a simple and expressive syntax for defining tests.

Ensure that these dependencies are installed in the project along with gcn-extension-tests.

Usage

To execute tests for VSCode extension using gcn-extension-tests, these steps should be followed:

1. Ensure that the extension's code and test files are set up correctly.
2. Open a terminal or command prompt in your project directory.
3. Run the following command to execute the extension tests:

./node_modules/gcn-extension-tests/bin/main.js [args]

The value of [args] can be one of the following:

• --runTest - executes all tests specified in out/test/site/index.js
• --runTest-ui - runs the UI tests with the vscode-extension-tester (files **/**.ui-test.js are being targeted for execution)
