Introduction

Are you preparing for a Cypress interview in 2025? Whether you're a beginner just getting started with automation or an experienced Quality Assurance Automation engineer aiming to advance your career, this guide covers the most commonly asked Cypress interview questions with clear, practical answers. From basic concepts to advanced test automation scenarios.

Why I'm Writing This

About a month ago, I got a message from a recruiter on LinkedIn about a Cypress automation role. I gave the interview and could only answer 13 out of 25 questions a tough moment, especially with 3 years of automation experience. That gave me the push to learn Cypress properly, and now I’m writing this guide to help you prepare better and avoid the mistakes I made.

Little About Me

I've worked with companies like Siemens and S&P Global, using tools like Cypress, Playwright, and API automation. If you’d like to know more about my work, feel free to connect with me on LinkedIn.

Basic Cypress Interview Questions and Answers

1. What is Cypress?

Cypress is a super handy JavaScript tool for testing web apps. It runs directly in the browser, which makes it really fast and easy to work with—plus, you get real-time feedback while your tests are running.

2. How is Cypress different from Selenium?

Cypress runs directly inside the browser and shares the same run loop as your app, which makes it faster and more reliable. On the other hand, Selenium uses WebDriver to control the browser from the outside, which often leads to flaky tests and a bit more setup hassle.

3. How much waiting time does Cypress use?

One cool thing about Cypress is that it automatically waits for elements to show up, animations to finish, and assertions to pass, so you don’t need to write extra waits. By default, it gives each command 4 seconds, but you can tweak that timeout globally or for specific commands.

4. What is describe() in Cypress?

describe() is used to group related tests so everything stays organized. It helps structure your test file better and makes things easier to read and manage. See the sample code below:

describe('Login functionality', () => {
  // test cases go here
})

5. What is it() in Cypress?

it() defines an individual test case inside a describe() block. It contains the actual steps and assertions for a specific scenario. Have a look at implementation:

it('should log in with valid credentials', () => {
  // test steps here
})

6. What is the fixtures folder in Cypress?

The fixtures folder is used to store static test data such as JSON files. This data can be loaded into tests using the cy.fixture() command.

7. Does Cypress support assertions?

Yes, Cypress supports both BDD-style (e.g., expect, should) and TDD-style (e.g., assert) assertions using Chai and Chai-jQuery libraries.

8. Does Cypress support multiple browsers?

Yes, Cypress supports testing in Chrome, Edge, Electron, and Firefox. However, it does not support Safari or Internet Explorer.

9. What is the default supported browser in Cypress?

The default browser Cypress uses is Electron, but you can easily run tests in Chrome, Edge, or Firefox using the Cypress Test Runner.

10. What is the purpose of cy.visit() in Cypress?

The cy.visit() command is used to load a web page in the browser during a test.

cy.visit('https://example.com')

11. Can we perform API testing in Cypress?

Yes, Cypress supports API testing using the cy.request() command, which allows you to send HTTP requests and assert on the responses.

12. How do you interact with DOM elements in Cypress?

You can use cy.get() to select elements using CSS selectors, then perform actions like click(), type(), etc.

cy.get('input[name="email"]').type('[email protected]')

13. Can we use BDD with Cypress?

Yes, you can use BDD with Cypress by integrating it with Cucumber using plugins like cypress-cucumber-preprocessor.

14. Can Cypress test APIs?

Yes, Cypress can test APIs directly using cy.request(), and it’s commonly used to validate API responses or set up test data.
