Using Code Lenses

Instructions

Test Explorer

If you wish to use the vscode test explorer integration, you will need to have Japa version 3.0.0 or higher to be able to use the --reporter flag.

Also note that you need to have the ndjson reporter activated in your Japa config file, since we are using it to communicate with the extension. ndjson is enabled by default if you don't have a reporters key in your config file. So if you have a reporters config, make sure to inclure ndjson in it.

import { configure, processCLIArgs, run } from '@japa/runner'
import { assert } from '@japa/assert'
import { ndjson, spec } from '@japa/runner/reporters'

processCLIArgs(process.argv.splice(2))
configure({
  files: ['tests/**/*.spec.js'],
  plugins: [assert()],
  reporters: {
    activated: ['spec'],
    list: [ndjson(), spec()], // 👈 Make sure to include ndjson
  }
})

Configuration

  • tests.npmScript: The npm script to run when executing tests. Defaults to test

    i.e if you set it to test:unit, the extension will run npm run test:unit --flags when executing tests

  • tests.enableCodeLens: Show CodeLenses above each test. Defaults to true

  • tests.watchMode: Run tests in watch mode when executed via shortcut/codelens. Defaults to false

  • tests.filePattern: The glob pattern to use when searching for tests. Defaults to **/*.{test,spec}.{ts,js}

  • misc.useUnixCd: Use Unix-style cd for windows terminals ( Useful when using Cygwin or Git Bash )

  • misc.disableNodeWarnings : Disable node warnings by setting NODE_NO_WARNINGS=1 when running tests. Defaults to true.

Keybindings

  • ctrl+shift+t: Run the test at the cursor position
  • ctrl+shift+f: Run the test file in the active editor

These keybindings can be easily changed in your VSCode configuration :

  • F1 -> Preferences: Open Keyboard Shortcuts
  • Type japa-vscode in the search bar
  • Change the japa-vscode.runTest or japa-vscode.runTestFile keybindings

Snippets
