One of Cypress's most essential and powerful use cases is having it run in your CI/CD pipeline. This way, every time you make a change to your codebase, your CI Pipeline will automatically run all of your Cypress tests to ensure that nothing has broken in your application.

Basics
Running Cypress in Continuous Integration is almost the same as running itlocally in your terminal. You generally only need to do two things: 1. Install Cypress 1. Run Cypress Depending on which CI provider you use, you may need a config file. You'll wantto refer to your CI provider's documentation to know where to add the commandsto install and run Cypress. For more configuration examples check out ourexamples.
Record tests
Cypress can record your tests and make the results available inCypress Cloud. Cloud gives you access to recordedtests - typically when running Cypress tests from yourCI provider- and provides youinsight into what happened when your tests ran.
Run tests in parallel
Cypress can run tests in parallel across multiple machines. You'll want to refer to your CI provider's documentation on how to set upmultiple machines to run in your CI environment. Once multiple machines are available within your CI environment, you can passthe --parallelflag to haveyour tests run in parallel. Read the full guide on parallelization.
Machine requirements
Hardware requirements to run Cypress depend how much memory the browser, theapplication under test, and the server (if running it locally) need to run thetests without crashing. Visit ourSystem Requirementsguide for minimum hardware recommendations. Some signs that your machine may not have enough CPU or memory to runCypress: 1. The recorded video artifacts have random pauses or dropped frames. 2. Debug logs of the CPU and memoryfrequently show CPU percent above 100%. 3. The browser crashes....
Dependencies
Cypress runs on many CI providers' virtual machine environments out-of-the-box without needing additional dependencies installed.
Caching
As of Cypress version 3.0, Cypressdownloads its binary to the global system cache - on linux that is~/.cache/Cypress. By ensuring this cache persists across builds you can saveminutes off install time by preventing a large binary download.
Missing binary
When npm or yarn install the cypress package, a postinstallhook is executedthat downloads the platform-specific Cypress binary. If the hook is skipped forany reason the Cypress binary will be missing (unless it was already cached). To better diagnose the error, addcommands to get information about the Cypress cacheto your CI setup. This will print where the binary is located and what versionsare already present. If the required binary version is not found in the cache, you can try thefollowin...
In Docker
If you are running long runs on Docker, you need to set the ipc to hostmode. This issuedescribesexactly what to do.
Xvfb
When running on Linux, Cypress needs an X11 server; otherwise it spawns its ownX11 server during the test run. When running several Cypress instances inparallel, the spawning of multiple X11 servers at once can cause problems forsome of them. In this case, you can separately start a single X11 server andpass the server's address to each Cypress instance using DISPLAYvariable. First, spawn the X11 server in the background at some port, for example :99.If you have installed xvfb on Linux or if...
The recommended approach is to install Cypress with npm because: Cypress is versioned like any other dependency. It simplifies running Cypress in Continuous Integration. yarn add. Installing Cypress via Yarn: cd /your/project/path. yarn add cypress --dev.

Aug 19, 2022 · Basics. Running Cypress in Continuous Integration is very similar to running Cypress locally in your terminal. In general, you will only need to do two things: Install Cypress npm install cypress --save-dev. Run Cypress Run Cypress. Depending on the CI provider that you are using, you may have to create a config file.
Aug 19, 2020 · I need to use Cypress in my Jenkins pipeline. Since downloading the cypress binaries takes way many minutes, I decided to create a docker image with cypress installed globally. I got a message saying that globally cypress installation is a bad practice, and I should install cypress as a depDependency.
Feb 27, 2023 · Step 1: Initialize the project. Create a folder named cypress-test and initialize your node project by running this command on your terminal. $ mkdir cypress-test $ npm init.
