Cypress - Modern Automation Testing from Scratch + Framework - Cypress Asynchronous Nature and its Promise Handling

The video tutorial covers web automation basics, focusing on key events like clicking, typing, and grabbing text. It introduces asynchronous behavior in JavaScript and how Cypress, built on Node.js, handles it. The tutorial explains promises, their states, and how Cypress ensures execution order using internal wrappers. It highlights the difference between synchronous and asynchronous execution, emphasizing Cypress's user-friendly approach by managing promises internally.

What are the three main events performed in web automation?

• Clicking, typing, and grabbing text

• Grabbing text, resizing, and scrolling

• Scrolling, clicking, and dragging

• Typing, scrolling, and resizing

What is the nature of JavaScript that affects tools built on Node.js?

• Asynchronous

• Synchronous

• Parallel

• Linear

How does asynchronous behavior affect the execution of steps?

• Steps execute only after the previous step is completed

• Steps execute one after another in order

• Steps execute in reverse order

• Steps execute simultaneously without waiting for each other

How does Cypress ensure sequential execution despite being asynchronous?

• By using a synchronous engine

• By queuing commands and running them in order

• By using a different programming language

• By ignoring asynchronous behavior

What does Cypress do to manage asynchronous behavior for the user?

• It uses a different programming language

• It ignores asynchronous behavior

• It automatically queues and executes commands in order

• It requires the user to handle it manually

What is the main difference between Cypress and Protractor regarding execution order?

• Cypress is synchronous, Protractor is asynchronous

• Cypress handles asynchronous behavior internally, Protractor requires manual handling

• Protractor is synchronous, Cypress is asynchronous

• Both handle asynchronous behavior the same way

What is a promise in the context of asynchronous operations?

• A method to speed up execution

• A guarantee of execution order

• A state or behavior of a step

• A way to handle errors

Which of the following is NOT a state of a promise?

• Pending

• Rejected

• Resolved

• Completed

What method is used to wait for a promise to resolve?

• .then()

• .async()

• .resolve()

• .wait()

Why is it important to understand the concept of promises in asynchronous operations?

• To ensure faster execution

• To handle errors effectively

• To manage execution order and state

• To write less code
