Speed and performance are important factors to consider when testing your app. Also, the other best option is to get rid of the unpleasant and repetitive elements so that the developer can focus more time on creating the app. Using a browser extension is a great approach to accomplish this while increasing your productivity.
Speed up documentation with browser extensions cross-browser testing A process used by QA engineers. Chrome, Firefox, Edge, Opera, and IE are just a few of the available browsers. online browser test.
and 64.8% of the marketChrome remains the most used browser among them.
We aim to build a vibrant open source community that benefits productivity, makes testing fun, and makes developers happy. In this attempt, this article takes a simple route that leads to a quicker solution, like the Cypress Chrome extension.
State-of-the-art front-end testing tools built for the modern web CypressCypress can test any program that runs in your browser. This end-to-end testing framework was built from the ground up and is uniquely positioned to go beyond the limitations of Selenium. You can complete your first successful test with Cypress in just 5 minutes!
prerequisite
Set up Cypress, start a new project and get things going. Start a new project with the following command:
$ mkdir cypress-tutorial
$ cd cypress-tutorial
$ npm init -y
The next step is to install the Cypress package as a development dependency.
$ npm install --save-dev cypress
Edit the package.json file in the root of your project and change the script properties as follows:
"scripts": {
"test": "npx cypress run",
"cypress:open": "npx cypress open"
},
Create and save a file called cypress.json in the project root folder and use it as a configuration file to tailor Cypress behavior to this particular project.
Add the following code to the file and save it.
{ "chromeWebSecurity": false }
Install Google Chrome
Windows, Android, iOS, macOS, and Linux users can easily download Google Chrome. Only an existing browser is required to access the download page or the App Store on her iOS. Instructions for installing the Google Chrome web browser on computers and mobile devices.
- visit Google Chrome download page for your web browser. Download Google Chrome using any web browser.
- There is a blue button in the middle of the page.
- If you don’t want Google to collect your usage data, uncheck the box below.
- Downloading the setup may take some time.
- Start setting up Chrome. To access the download icon using his Finder or File Explorer on a Mac or Windows computer, click the download symbol in your browser (Mac).
- It should look something like ChromeSetup.exe. Double-click the .exe file to start the setup.
- Installing this may take some time. Google Chrome will launch as soon as it’s done. You can now make it your default browser.
Install Node.js and npm
- To publish and install packages to or from public or private npm registries, you need to install Node.js and the npm command line interface using the Node version manager or Node installer.
- We highly recommend installing Node.js and npm using a node version manager such as nvm.
- Using the Node installer installs npm in a directory with local permissions, so running npm packages globally can cause permission errors, so you can’t use it.
Get the latest version of npm by running the following command in your command line::
npm install -g npm
macOS or Linux Node version manager
Windows node version manager
Plugin
Plugins can be used to access, modify, or extend Cypress’s internal functionality. As a user, all test code, applications, and Cypress commands typically run in a browser. Another her Node process that plugins might use is Cypress.
The npm module is Cypress official listThey can be updated independently of Cypress, so they can be versioned and upgraded separately.
All released plugins can be installed using NPM:
npm install <plugin name> --save-dev
- Cypress configuration requires the plugin to be included in the setupNodeEvents function of Cypress version 10.0.0.
- If you are still running an older version of Cypress, you can include your plugin in the (deprecated) plugin file.
example:
const { defineConfig } = require('cypress')
module.exports = defineConfig({
// setupNodeEvents can be defined in either
// the e2e or component configuration
e2e: {
setupNodeEvents(on, config) {
// bind to the event you care about
on('<event>', (arg1, arg2) => {
// plugin stuff here
})
},
},
})
Cypress is a node module, so to handle Chrome extensions, you need to add the npm plugin using the command below.
$ npm install -g -- save-dev cypress-browser-extension-plugin
Project plugin file:
// cypress/plugins/index.js
const extension loader = require('cypress-browser-extension-plugin/loader');
module.exports = (on) => {
on('before:browser:launch', extensionLoader.load('/path/to/your/extension'));
}
In the project’s support files:
// cypress/support/command.js
const addExtensionCommands = require('cypress-browser-extension-plugin/commands');
addExtensionCommands(Cypress);
In the project’s support files:
// cypress/support/command.js
const addExtensionCommands = require('cypress-browser-extension-plugin/commands');
addExtensionCommands(Cypress);
Just press the following command and Cypress will launch with only one extension loaded.
$ npx cypress open
Select the spec file, loadChromeExtension.spec.js.

Rapid, hassle-free parallelization allows you to achieve results faster without sacrificing accuracy. You can test your software in real-life usage scenarios and catch bugs before your users do.
closing note
It’s easy to install Cypress, write tests, debug tests, and integrate into continuous integration. Cypress works directly in the browser and has its own way of manipulating the DOM. We support several Chrome browser versions in addition to many other browsers.
