Cypress vs Selenium vs Playwright vs Puppeteer

Many teams prefer based on trends sooner than real product needs. I ’ ve perform this myself—adopting a democratic tool only to spend days debugging flaky test and rewriting scripts.

No amount of configuration fixes aid, because the subject wasn ’ t the trial, but the framework fit.

That experience alter how I evaluated automation tools. Understanding the core differences between democratic automation tools include Cypress, Selenium, Playwright, and Puppeteer is essential to take the right one.

This clause compares Cypress, Selenium, Playwright, and Puppeteer, outlining their lineament, benefit, limitations, and better use cases to help teams take the right testing model.

What is Cypress?

Cypress is a mod, JavaScript-based fabric designed for screen instantly in the browser.

Unlike traditional instrument, Cypress runs inside the browser alongside the covering, giving it deep access to the DOM, web requests, and application state.

It is particularly popular among frontend developer because of its mere setup, fast executing, and interactive test runner that allows real-time debugging.

is best suit for testing modern web covering where quick feedback, developer productiveness, and tight integration with the frontend stack are precedence.

How to run Cypress Tests

1. Visit the following URL to start up your Cypress environs:https: //nodejs.org/en/download/
2. Upon closing of the download, a nodejs file is generated in the Program file.
3. Then set environment variables.
4. Enter environs variable in the Start.
5. Go to Advanced in the System Properties pop-up and select Environment Variables. then press OK.
6. Navigate to the System variables section of the Environment Variables pop-up and select New.

macOS: How to Set Environment Variable

1. Launch Terminal to get depart.Navigate to Go & gt; Utilities & gt; Terminal.
2. Spotlight is too a practicable option for establish the Terminal. To activate Spotlight, press the Command key and the infinite bar at the same moment. All you hold to do is type Terminal and imperativeness enter.

Commands for Setting Environment Variables

According to Apple, you must use the proper shield bid to pair a variable name with a value in order to update an environment variable & # 8217; s value.

% PATH=/bin: /sbin: /user/bin: /user/sbin: /system/Library/ export PATH

Here, the value would be

/bin: /sbin: /user/bin: /user/sbin: /system/Library/

The varying PATH is set by putting & # 8220;% PATH=& # 8221; before the value and & # 8220;export PATH& # 8221; after the value.

This command, according to Apple, allows you to analyze all environmental variables:

% env

Next, a JavaScript editor is required so that you can make the Cypress code. For this, you can approach the URLhttps: //code.visualstudio.com/and download Visual Studio Code.

• From the File menu, prefer the Open Folder choice. Add the previously made CypressAutomation booklet to Visual Studio Code after that.
• You need to create thepackage.jsonfile using the following terminal command.

npm init

You must input info such as the package & # 8217; s gens, description, and other details.

Finally, execute the undermentioned command to install Cypress.

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

npm install cypress -- save-dev
