20 Cypress Interview Questions to Ace Your Next Interview

Since the testing tool is so important to current software delivery processes, and there is so much pressure to get work done quicker, the need for reliable automated test tools is growing steadily. There are a variety of open-source frameworks out there that can help with these kinds of user requests. Cypress interview is a famous test tool that has rapidly made a name and is widely used for automating web integration and End to End testing using Cypress.

Interviews can give you nightmares, no matter how much you are efficient at something. But we’ve got your back! This article introduces some of the most crucial Cypress interview questions to give a heads-up about how the interview might look.

We’ll begin with easy questions and progress to more difficult ones.

Most Common Cypress Interview Questions:

1) What is Cypress?

Cypress is a nodejs application used for testing front-end javascript applications. Cypress simplifies and improves test automation by running tests directly in the browser.

2) Describe the architecture of Cypress

A Node server process backs Cypress. Cypress and the Node process are in continual dialogue, coordinating and carrying out actions on behalf of one another. Cypress also performs its operations at the network level by dynamically reading and modifying data transfers over the internet. This allows Cypress to alter not just the data entering and leaving the browser but also any code that may potentially cause problems with the browser’s automation.

3) Which aspects of Cypress are most notable?

  1. With Cypress, you can use the browser to perform tests and carry out tasks. Tests are more reliable and take significantly less time.
  2. Instantaneous hold
  3. Cypress may record interim states during test runs. There is no need to set up third-party plugins like Selenium.
  4. Assertions may be used right away.
  5. Traffic management in networks

4) What web browsers does Cypress work in?

Cypress is compatible with Chrome, Canary, Microsoft Edge, Electron, and Mozilla (beta support). 

5) What are the two key differences between Cypress vs. Selenium?

Cypress only supports JavaScript and Typescript languages, whereas Selenium can work with C#, Java, Python, Ruby, and many more. Cypress only supports Chrome, Firefox, and Edge, whereas Selenium is compatible with all main browsers.

6) Does Cypress provide a testing framework?

As an alternative to Junit and TestNG, Cypress provides the Mocha and Chai assertion libraries.

7)How can I work with Cypress’s DOM elements?

It’s important to note that CSS Selector is the only one supported by Cypress.

8) Does Cypress support BDD?

Although Cypress does not have native support for BDD, you can create your tests in BDD Cucumber Syntax with the help of the NPM Cypress-Cucumber-Preprocessor plugin and have them immediately converted into Cypress.

9) How can you write your commands in Cypress?

A Cypress user may create their command from scratch or modify a current one.  The iterative test steps that make up an automation flow are developed using these unique commands. Create your commands in cypress/support/commands.

 Several predefined commands, including cy.visit, cy.reload, and others, are preinstalled in Cypress. Cypress allows us to create our specialized commands. 

10) How do you put “Keypress” in Cypress?

Cypress’s.type() method allows users to write text into the program. Keyboard shortcuts need to be qualified with brackets if we want to use them (this includes CTRL, SHIFT, ALT, etc.

11) What is a Cypress environment variable?

The Environment Variables have their values set independently of any specific program or framework in the operating system.

12) Can you tell me about Cypress’s preserved cookies?

By default, Cypress deletes cookies after each test. The preserve cookies option in Cypress may be used to prevent deleting cookies.

13) What Is Shadow DOM?

Shadow DOM enables the addition of hidden DOM trees to regular DOM tree nodes, with a “shadow root” node in its center.

14) Please provide me a rundown of the folder hierarchies used by Cypress.

Cypress provides a suggested directory layout after installation. There are essentially four primary file locations:

  • The fixtures directory houses any external static data or objects utilized in the tests. In most cases, JSON is used to store data.
  • In the next folder, called “integration,” you should store all of your tests. This is where you’ll find your spec files. The test file has many valid formats: .js, .jsx, .coffee, and .cjsx.
  • It is self-contained, with its index.js file, and may be used with various plugins. This is where you should put the code for any plugins you’ve created.

16) How many Cypress assertions are there?

The following are assertions available in Cypress:

  • Chai BDD Assertions: not, include, ordered, any, equal, etc.
  • Chai TDD Assertions: .isOK(), .isTrue(), .strictEqual() etc
  • Chai JQuery Assertions: visible, hidden, selected, checked, enabled, etc.
  • Sinon-Chai Assertions: called, callCount, calledOnceWith, calledWithExactly, etc.

17) How does Cypress store test data? 

The Cypress Fixture command allows us to Load a predefined data set from a specified file. The fixtures directory in Cypress contains “JSON” files that may be used to store test data that many tests can access. Key-value pairs store test data, which may then be accessed in the actual test scripts.

18) What elements make up Cypress?

A cypress is made up of two parts:

  • Cypress Test Runner’s Features Test Results, URL Preview, Viewport Resize, Command Log, and Application Preview
  • The Cypress Dashboard is a service that lets you see past executions of automated tests.

19) How to address utility in the Cypress framework?

  • Cypress’s Support folder contains the index.js and commands.js files by default.
  • Every test file begins with index.js. In this directory, we may store reusable behaviors like custom commands.

20) Please explain the limitations of the Cypress testing environment.

  • There’s no coding language other than JavaScript that it can run.
  • There is no direct support for using several tabs at once. There is a workaround for the problem.
  • No ability to run several browser instances simultaneously.
  • The driver doesn’t work with Safari or IE.
  • No direct assistance for Cypress. Solutions exist.
  • It is not possible to test on a mobile device.
