jest test description inside it code example

Example 1: beforeeach jest

describe('some testing', () => {
  let isCity;
  
  beforeEach(() => {
    isCity = 'Vienna';
  });

  afterEach(() => {
    isCity = null;
  });

  test('city database has Vienna', () => {
    expect(isCity('Vienna')).toBeTruthy();
  });

  test('city database has San Juan', () => {
    expect(isCity('San Juan')).toBeTruthy();
  });
}

Example 2: jest it vs test

// In the docs it says: 
// it is an alias of test. So they are exactly the same.
// it() -> test()
