"mocha.runTestsOnSave": {
    "default": "false",
    },

Setting a keyboard shortcut

To quickly run tests, you can create a keyboard shortcut under File > Preferences > Keyboard Shortcuts. For example, the following JSON will run all tests with CTRL+K followed by R key.

{
  "key": "ctrl+k r",
  "command": "mocha.runAllTests"
}

Following commands are also supported:

Command	Title
mocha.runAllTests	Mocha: Run all tests
mocha.runFailedTests	Mocha: Run failed tests
mocha.runLastSetAgain	Mocha: Run last set again
mocha.runTestAtCursor	Mocha: Run tests matching the current cursor position or the current active file
mocha.runTestsByPattern	Mocha: Run tests matching a pattern
mocha.selectAndRunTest	Mocha: Select and run a test

How it works

By default, this extensions will discover tests by searching for test/**/*.js under your workspace.

Because your tests may requires a newer version of Node.js than the one powering Visual Studio Code, thus, this extension will attempt to find your installed Node.js and use it for your tests. It will search for the installed Node.js as indicated by environmental variable PATH. You can find the logic here.

When the test is being run, we will add NODE_PATH to point to your workspace node_modules folder to help resolving external modules.

When you ask to run the test under cursor position, the extension will parse the current file and look for matching tests or suites. If the file contains tests or suites defined using template strings or via dynamic generation, the regular expression (.+) will be used as a placeholder in order to have a better matching without having to evaluate the file twice. This implies that more tests than expected might be run.
