How to Use Async/Await in Cypress

The simplest way to handle asynchronous code in Cypress is by using async/await. To use asyn/await in Cypress, we can go with two different options. First, we can use an immediately invoked function expression, or IIFE for short:

(async () => {
    const user = await service.getUser(Id);

    expect(user).to.deep.equal({ ... });
})();

We can also define callback functions as async and use await inside them like so:

service.deleteUser(Id).then(async () => {
  const user = await service.getUser(Id);

  expect(user).to.be.null;
});

It is also important to mention that although Cypress commands are not Promises - the API is very similar. This means we can chain a then callback from commands and make the callback async in order to use await after executing commands:

cy.get('button')
  .click()
  .then(async () => {
      // Await your asynchronous code here
  });
