What are @types/mocha's main functionalities?

Describe blocks

TypeScript definitions for Mocha's describe blocks, which are used to group related tests.

describe('Array', () => {
  describe('#indexOf()', () => {
    it('should return -1 when the value is not present', () => {
      assert.equal([1, 2, 3].indexOf(4), -1);
    });
  });
});

It blocks

TypeScript definitions for Mocha's it blocks, which are used to define individual test cases.

it('should add two numbers', () => {
  const sum = add(1, 2);
  assert.equal(sum, 3);
});

Hooks

TypeScript definitions for Mocha's hooks like before, after, beforeEach, and afterEach, which are used to set up preconditions and clean up after tests.

describe('hooks', () => {
  before(() => {
    // runs once before the first test in this block
  });

  after(() => {
    // runs once after the last test in this block
  });

  beforeEach(() => {
    // runs before each test in this block
  });

  afterEach(() => {
    // runs after each test in this block
  });
});
