noDoneCallback (not released)

Diagnostic Category: lint/nursery/noDoneCallback

Source: no-done-callback

Disallow using a callback in asynchronous tests and hooks.

This rule checks the function parameter of hooks & tests for use of the done argument, suggesting you return a promise instead.

Examples

Invalid

beforeEach(done => {
    // ...
});
