Globals

None of the globals are within the __helpers module.

chai

config as chaiConfig

The config module: https://www.chaijs.com/guide/styles/#configuration

AssertionError

This is the AssertionError class from the assert module.

logover

The logger used by freecodecamp-os: https://www.npmjs.com/package/logover

This is mostly useful for debugging, as any logs will be output in the freeCodeCamp terminal.

ROOT

The root of the workspace.

watcher

The Chokidar FSWatcher instance.

This is useful if you want to stop watching a directory during a test:

const DIRECTORY_PATH_RELATIVE_TO_ROOT = "example";
watcher.unwatch(DIRECTORY_PATH_RELATIVE_TO_ROOT);
// Do something
watcher.add(DIRECTORY_PATH_RELATIVE_TO_ROOT);

Collisions

As the tests are run in the evaled context of the freecodecamp-os/.freeCodeCamp/tooling/tests/test-worker.js module, there is the possibility that variable naming collisions will occur. To avoid this, it is recommended to prefix object names with __ (dunder).
