Cypress automation testing framework index.
Cypress is a modern web front-end testing tool built with JavaScript Mocha. Cypress testing operates directly on the browsers without the need for Selenium.

Selenium is still the most influential and well-developed framework for web automation testing. Being one of the best automation frameworks with constantly evolving features, it is poised to lead the industry in all aspects as compared to other trending frameworks like Cypress, Puppeteer, PlayWright, etc. Furthermore, using Selenium gives you the flexibility to use different programming languages like C#, Ruby, Perl, Java, Python, etc., and also accommodate different operating systems and web browsers for Selenium automation testing.
It is a fact that software testing is time and resources consuming. Testing the software can be observed from different perspectives. It can be divided based on what we are testing. For example, each deliverable in the project, like the requirements, design, code, documents, user interface, etc., should be tested. Moreover, we may test the code based on the user and functional requirements or specifications, i.e., black-box testing. At this level, we are testing the code as a black box to ensure that all services expected from the program exist, work as expected, and with no problem. We may also need to test the structure of the code, i.e., white box testing. Testing can also be divided based on the sub-stages or activities in testing, for instance, test case generation and design, test case execution and verification, building the testing database, etc. Testing ensures that the developed software is, ultimately, error-free. However, no process can guarantee that the developed software is 100% error-free.
Selenium, a project hosted by the Apache Software Foundation, is an umbrella open-source project comprising a variety of tools and libraries for test automation. Selenium automation framework enables QA engineers to perform automated web application testing using popular programming languages like Python, Java, JavaScript, C#, Ruby, and PHP.
Selenium has always been the most preferred test automation framework for testing web applications. This open-source framework supports popular programming languages (e.g. Java, JavaScript, Python, C#, etc.), browsers, and operating systems. It can also be integrated with other test automation frameworks like JUnit, TestNG, PyTest, PyUnit, amongst others. As per the State of open source testing survey, Selenium is still the king for web automation testing, with 81% of organizations preferring it over other frameworks.
Automation testing is a fast-growing industry, and every tester tends to opt for tools and frameworks that are self-sufficient and offer useful features out of the box. Though there are a number of test automation frameworks like Selenium, Cypress, etc; I still prefer using Selenium.
Cypress is a renowned Javascript-based open-source, easy-to-use end-to-end testing framework primarily used for testing web applications. Cypress is a relatively new player in the automation testing space and has been gaining much traction lately, as evidenced by the number of Forks (2.7K) and Stars (42.1K) for the project. LambdaTest’s Cypress Tutorial covers step-by-step guides that will help you learn from the basics till you run automation tests on LambdaTest.
You can elevate your expertise with end-to-end testing using the Cypress automation framework and stay one step ahead in your career by earning a Cypress certification. Check out our Cypress 101 Certification.

EDIT 2: This solution was written for Cypress ~3.6.0 or thereabouts so it's possible that newer versions of Cypress work very differently internally, even if you fix some superficial incompatibilities of this code.
EDIT: often someone suggests using Promise.all
, which is not a correct solution. Cypress chainer objects aren't Promises/A+-compatible, they simply appear to be promises because they implement .then
interface. That's why Promise.all
is able to consume an array of chainer objects, but that's it. The resolution values passed to Promise.all().then
callback is not going to be what you expect (see https://github.com/cypress-io/cypress/issues/915).
You can use a helper I've suggested in a similar answer:
// put this in cypress/support/index.js
const chainStart = Symbol();
cy.all = function ( ...commands ) {
const _ = Cypress._;
const chain = cy.wrap(null, { log: false });
const stopCommand = _.find( cy.queue.commands, {
attributes: { chainerId: chain.chainerId }
});
const startCommand = _.find( cy.queue.commands, {
attributes: { chainerId: commands[0].chainerId }
});
const p = chain.then(() => {
return _( commands )
.map( cmd => {
return cmd[chainStart]
? cmd[chainStart].attributes
: _.find( cy.queue.commands, {
attributes: { chainerId: cmd.chainerId }
}).attributes;
})
.concat(stopCommand.attributes)
.slice(1)
.flatMap( cmd => {
return cmd.prev.get('subject');
})
.value();
});
p[chainStart] = startCommand;
return p;
}
usage:
it('test', () => {
const urls = [
'https://en.wikipediaaa.org',
'https://en.wikipedia.org'
];
cy.all(
...urls.map(url => cy.request(url))
).then(responses => {
responses.forEach( resp => {
expect(resp.status).to.eq(200);
});
});
});
That being said, you can also do this:
const urls = [
'https://en.wikipediaaa.org',
'https://en.wikipedia.org'
];
let passes = 0;
urls.forEach( url => {
cy.request(url).then( resp => {
if ( resp.status === 200 ) passes++;
});
});
cy.then(() => {
expect(passes).to.eq(urls.length);
});
The cy.all
helper atop is really useful if you want to access the results without having to keep around globals and accessing them from a cy.then()
callback --- but like I've shown in the last example, everything can be worked around using just vanilla cypress.
Or, if you don't need responses at all, you can simply do:
const urls = [
'https://en.wikipediaaa.org',
'https://en.wikipedia.org'
];
urls.forEach( url => {
cy.request(url).its('status').should('eq', 200);
});
