Cypress Interview Questions and Answers:

1) How would you describe the Cypress framework?

Ans: Cypress's main characteristics include the following:

• This tool can run tests and perform commands in the browser, making tests faster and less flaky.
• It can take screenshots of tests when each step is completed.

In addition, cypress provides network traffic control, built-in assertions, and automatic wait.

2) Cypress is what kind of framework?

Ans: Cypress is a JavaScript-based end-to-end testing framework built on mocha. This feature-rich JavaScript test framework runs on and in the browser, making asynchronous testing simple and convenient.

3) What are Cypress's limitations?

Ans: Create JavaScript tests. Cypress can only utilize Node because JavaScript is the world's most famous programming language.

• There is no multi-tab support.
• *Cypress is a slower wood.
• Maintenance.
• The syntax could be more complex and consistent.

4) Can we use testing in conjunction with cypress?

Ans: Yes. Allows you to define a set of fixed, particular data states for a collection of tests (group fixtures).

5) Is Cypress a BDD or TDD system?

Ans: Cypress is a JavaScript-based end-to-end testing framework built on top of mocha. This feature-rich JavaScript test framework runs on and in the browser, making asynchronous testing simple and convenient. It also pairs with any JavaScript testing framework using a BDD/TDD assertion library and a browser.

6) What makes cypress quicker than Selenium?

Ans: Cypress, as a tool, is suited for introducing developers to test automation rather than serving as a replacement for Selenium. This is why cypress is one of the world's fastest-growing automation tools. Selenium, on the other hand, is a more general-purpose tool for a larger audience.

7) Is it possible to utilize BDD in Cypress?

Ans: A cucumber is a tool that aids and supports Behavior Driven Development (BDD). Cypress integrates with Cucumber to allow you to write test scenarios in BDD format. Cypress takes advantage of Cucumber's capabilities by utilizing the Cucumber-preprocessor node module.

8) What language is spoken in cypress?

Ans: Greek Cypriots speak Cypriot Greek as their everyday language (vernacular), while Turkish Cypriots speak Cypriot Turkish. The standard languages (Standard Modern Greek and Standard Turkish) are utilized for official purposes.

9) Can cypress support many tabs?

Ans: Cypress instructions are executed within a browser. Multiple browser tabs will never be supported. Cypress cannot drive two browsers at the same time.

10) Does cypress support XPath

Ans: It should be noted that cypress also supports Xpath selectors. That, however, does not happen by accident. To put it another way, we need 'Cypress-Xpath' external plugins to help this selector.

 

Cypress Interview Questions for Experienced

1) How would you characterize the Cypress testing tool?

Ans: Cypress is a front-end testing tool that uses Javascript. It was created with node js. The tool is useful for running tests in a browser. In this way, it can make the entire testing process more trustworthy and simpler.

2) How will you set up cypress?

Ans: To install cypress, we must first install Node. After that, we can use the command npm to install the cypress.

3) Could you explain the Cypress architecture?

Ans: A Node server process powers this utility. The Node process and cypress constantly synchronize, communicate, and execute tasks on each other's behalf. Not only that, but cypress also functions at the network layer, changing and reading web traffic at the same time. This allows cypress to alter everything that comes through the browser.

4) What exactly is Cypress CLI?

Ans: Cypress CLI is useful because it allows you to run Cypress tests from the command line. One such feature is used in the Pipelines to execute the Cypress tests. It also provides Flags Control and Options for the Cypress Test Behaviour.

5) Please list some of the browsers that cypress supports.

Ans: Cypress is compatible with the following:

• Electron 
• Firefox 
• Edge
• Chromium
• Chrome

6) How can you tell the difference between Cypress and Selenium?

Ans:

• Cypress only supports the Typescript and JavaScript programming languages. Selenium, on the other hand, supports all of the major programming languages, including C#, Python, Java, Ruby, JavaScript, and others.
• While Selenium supports all major browsers, cypress only supports a handful.
• The configuration in Selenium is complicated. Cypress contains ready-to-use frameworks.

7) What testing frameworks are included with cypress?

Ans: Cypress comes with the assertion libraries Chai and Mocha. However, we are unable to use TestNG or Junit in Cypress.

8) In cypress, how can you interact with DOM elements?

Ans: In cypress, we may utilize CSS Selector to communicate with DOM components.

9) What exactly do you mean by "hooks" in cypress?

Ans: Cypress hooks are commonly used to specify or define preconditions we want to perform before each test or a set of tests. After each (), after (), beforeEach (), and before are some of the accessible hooks ( ).

10) In the Cypress framework, how will you handle reusability?

Ans: Cypress includes the commands.js and index.js files in the Support folder by default. Index.js is executed before each test file. We can store reusable behavior in this folder, such as global override and custom commands.

11) In cypress, what do you mean by automation?

Ans: Cypress automation is a procedure that executes a Test Code in conjunction with the app. This test cannot be carried out in a single loop. It does, however, take place in a single browser. Node.js Server is commonly employed in actions outside of the computer.

12) What is Cypress run? 

Ans: Cypress Run helps in the execution of Cypress tests in Headless Browsers. It also aids in the opening of a new browser tab. It is also useful in loading the tool at the URL Cypress, which was previously installed from the same. Cypress aids in the discovery of cypress.json. Furthermore, it keeps running tests on the webpack monitor.

13) Which selectors does Cypress support?

Ans: This tool only supports CSS selectors by default. However, we can utilize third-party plugins to access the Xpath selectors.

14) How will you launch the Cypress window and run tests?

Ans: After we've installed the cypress, we can access the npm cypress open command. The tests can then be run by clicking on the test file name.

15) How do I view the tool's default configuration?

Ans: Under the Cypress window Test Runner, you can see the default configuration. There, you must select Settings & Configurations.

Cypress Automation Interview Questions

1) Is XPath support available in cypress?

Ans: Cypress does not support XPath by default. However, with the Cypress-Xpath plugin, we can utilize XPath to interact with all DOM components. We can use npm to install the plugin.

2) How should the Cypress framework manage reusability?

Ans: Cypress includes index.js and commands.js by default in the Support folder. Index.js is executed before each test file. We can store reusable behavior in this folder, such as custom commands and global overrides.

3) What are the disadvantages of the Cypress testing software?

Ans:

• Only JavaScript is supported.
• There is no support for multiple tabs.
• Iframes are not permitted.
• Only Web Testing is supported.

4) How can we dynamically update the baseUrl in cypress?

Ans: Using the CLI Command, we can alter the baseUrl in cypress dynamically.

5) Is mocha used by cypress?

Ans: Cypress has expanded mocha and used its bdd syntax for unit and integration testing.

7) In cypress, how do I press the button?

Ans: To click an element on cypress, use the.click() function. The element function should be connected with the click function. That is, we must first obtain the desired element before clicking.

8) In cypress, how do I make suites?

Ans: We can construct a describe() block. The described block serves as a suite, and each test can be built as a separate it() block within it. Describe() functions similarly to a suite in this context.

9) Why should I write my tests in the integration folder when I can write them in other folders?

Ans: In cypress, the default tests folder is integration. Therefore when we run the tests, it will look in the integration folder for all test files.

However, you can construct the tests in a different location; in that case, you must alter the configuration and specify where your integration folder is located using the "integrationFolder" option.

10) Which selectors will be supported by cypress?

Ans: By default, cypress only supports CSS selectors. To support Xpath selectors, we can use a third-party plugin.

11) What exactly is an environment variable in cypress?

Ans: The Environment Variables are variables whose values are determined at the operating system level, independent of the application or framework.

12) What are Cypress Preserve Cookies?

Ans: By default, cypress clears the cookies after each test. To avoid removing cookies, use cypress's preserve cookies option.

13) What precisely are Cypress custom commands?

Ans: Cypress has a collection of default commands such as cy. Visit, cy. Reload, and so on. In cypress, we can also create our custom commands.

14) What precisely is Shadow DOM?

Ans: Shadow DOM enables the addition of disguised DOM trees to standard DOM tree components — this shadow DOM tree starts with a shadow root.

15) What is the Testing Framework that Cypress includes?
