Run Online Cypress Parallel Testing

Cypress is an open source end-to-end test automation framework written in JavaScript and based on Mocha and Chai. With Cypress you can automate tests on browsers like Firefox, Chrome, Brave & Edge family. Cypress is known for easy to set up, faster test execution, debugging capabilities and an active community.

Cypress first runs the test code to read and queue all the commands it needs to execute, then loads the page, and finally executes one by one all the commands previously queued.

Cypress allows you to run tests in parallel across multiple machines since version 3.1.0. However, testing in parallel on a single machine can take significant resources, so it is recommended to use a cloud-based test execution platform like LambdaTest for running cypress parallel tests.

LambdaTest provides a cloud grid of 40+ browser versions for chrome, firefox and edge. To perform cross browser testing with cypress all you need to do is specify the browser os combination in lambdatest.json file and execute the test.

Use the lambdatest.json file to set the parallelization first. Trigger the tests using lambdatest-cypress run by specifying the number of parallel tests you want to run.

LambdaTest is one of the most powerful platforms that helps you scale faster with its robust, reliable & secure cloud grid. You can trigger cypress tests instantly on 40+ browser versions (more to come) and moreover get features that aid you to execute tests and deploy faster.

Cypress supports only JavaScript whereas Selenium supports all programming language. Cypress browser support is also limited as compared to Selenium. However, Cypress helps in faster test execution and is more developer-friendly in comparison to Selenium. To know the key differentiators of you can read our blog on Cypress vs Selenium.

Yes! To run Cypress tests using a CI/CD pipeline, you need to clone your test repository, then install the LambdaTest-Cypress CLI and, setup application servers. (if needed)
