Modern Testing with Cypress: The Ultimate Guide

Why choose Cypress?

Cypress decodes many of the main testing bottlenecks designers face regularly. It is a JavaScript-based end-to-end testing framework that doesn't use Selenium (the most widely utilised for testing) at all. It is built on top of Mocha, and Mocha's part is the Javascript test framework operating on the browser, which makes asynchronous testing simple. Cypress automatically remains for the loading of DOM stuff, elements to be visual, AJAX calls to be finished, etc. Therefore, we don't require the use of implicit and explicit waits.

Another benefit Cypress delivers to designers is that it runs instantly in the browser with no network transmission. The architecture makes testing and growth happen simultaneously. It lets designers have access to tools, and they can make modifications and see them mirrored in real-time. Naturally, this lends more precision and speed to the whole operation.

Features of Cypress:

Time travel:Cypress brings snapshots as your test runs.

Debuggability: Cypress can imagine why a test case has failed.

Automatic waiting: There is no requirement to use delay or sleep because it automatically waits for your commands.

Spies, stubs, and clocks: demonstrate and manage the conduct of functions, server response, and timer.

Screenshot and video:Cypress Testing automatically grabs screenshots when your test case falls and makes a video of the finished effect when it is run from the CLI.

• Advantages of Cypress:
• Open-source
• It has promised support.
• Java script testing framework
• Comfortable and reliable testing
• Fast, free, and open-source
• easy to manage our response, headers, and status.
• Helps you see the locator

Installing Cypress:

Installing Cypress is an effortless task corresponding to a Selenium installation. There are two powers used to install Cypress on devices. These are,

• npm init
• npm install Cypress
• The foremost command is used to make a "package.json" file, and the second command is used to install all Cypress dependencies.

Project Folder Structure Details:

Project folder structure elements as below,

Node_modules folder: This is the manual for building devices.

*package.json file: The file in the app root explains where libraries will be installed into node_modules when you run "npm install".

*Cypress folder: It has folders like fixtures, integration, plugins, screenshots, support, and video.

These folder components are listed below:

Fixture: This folder is used to store external pieces of static data and can be used for your test.

Integration: This folder is used to write the test case for your app.

Screenshot -This folder stores screenshots from your test.

Video: This is used to keep videos in your test.

Support: This folder is used to document the common commands file.

Write your sample program in Cypress:

Step 1: Open your Visual Studio code on your machine.

Step 2: Make a new Cypress project folder and title it "Cypress E2E."

Step 3: Open the command line and go to the above-created task path.

Step 4: Type the foremost command under the "Installing Cypress" heading, then wait for it to make a package.json file.

Step 5: After that, type the second command.

Step 6: The above task will complete within 2-3 minutes after starting the Cypress and node_modules folders inside the "cypress e2e" folder. This folder will also have a "json" file.

Step 7: Click the Cypress folder under "cypress e2e" in the VS Code.

Step 8: The automation carrier details are as below:

We will use the CloudIQ home page link for this automation.

Step 9: Make the "cypress Automation.spec.ts" file under the integration folder and write the programme.

Programme Explanation:

• Here is what the test script given above does:
• Navigate to the "Cloudiqtech" site.
• Wait for 10 seconds for the page to load.
• Next, click on the "AWS" reference link.
• Then navigate to the "AWS" page.
• Ultimately, validate the existing page as the AWS page.
• Step 10: Extend the command terminal, then go to your Cypress project path, then run

D:cypress test ./node_modules/.bin/cypress open

Step 11: After staying for 1-2 minutes, it will open the Cypress Terminal app. It has all the tests, like the ones you wrote in your automation tests and the default tests.

Step 12: Click your "Cypress Automation.spec.js" file; this automatically extends the default Chrome browser to run your difficulty and makes a test coverage report in your browser.

Component testing

Cypress gives us the ability to test the features of a web page. This part of the testing is available from Cypress versions 10 and above. Usually, the designers use part testing when installing and testing components from numerous front-end UI libraries.

For example, in the picture below, we have a test to assert that a button component has the correct text.

Moreover, we can maintain the background colour, styles, and appearances using component testing.

Conclusion

From the above elements that Cypress delivers, we can conclude that Cypress is one of the best automation tools to automate our applications.

FAQs

Can we use testing with Cypress?

With Cypress, you can easily create tests for your modern web applications, debug them visually, and automatically run them in your continuous integration builds.

Is Cypress the future for testing?

It's easy to use, reliable, and has a rich feature set that makes it perfect for testing modern web applications. If you're looking for an automated testing tool that's built for the 21st century, then Cypress is the tool for you.

Is Cypress good for UI testing?

Cypress is a great tool with a growing feature set. It makes setting up, writing, running, and debugging tests easy for QA automation engineers. It also has a quicker learning cycle with a good, baked-in execution environment.

What kind of testing is Cypress used for?

Cypress is a purely JavaScript-based front-end testing tool built for the modern web. It aims to address the pain points that developers or QA engineers face while testing an application. Cypress is a more developer-friendly tool that uses a unique DOM manipulation technique and operates directly in the browser.
