## Arrow functions

Passing [arrow functions]( to Mocha is discouraged. Their lexical binding of the `this` value makes them unable to access the Mocha context, and statements like `this.timeout(1000);` will not work inside an arrow function.

## Hooks

Mocha provides the hooks `before()`, `after()`, `beforeEach()`, and `afterEach()`, which can be used to set up preconditions and clean up after your tests.
