How to incorporate Puppeteer e2e tests into GitLab CI/CD pipeline?

Hey everyone, I need some help with my GitLab CI/CD setup. I’ve been working on end-to-end tests using Puppeteer for Chrome, and now I want to make these tests part of our deployment process.

My goal is to run these tests automatically before each production deployment. If the tests pass, the deployment should proceed. If they fail, I want the deployment to be stopped.

I’m already using GitLab’s pipeline for our automated deployments. What I’m struggling with is how to add my Puppeteer tests to the gitlab-ci.yml file. Has anyone done this before? Any tips or examples would be super helpful!

I’m not sure if I need to create a separate job for the tests or if there’s a way to integrate them into an existing stage. Also, how do I make sure the deployment only happens if the tests pass? Thanks in advance for any advice!

hey alex, i’ve done this before! u can add a new job in ur .gitlab-ci.yml for puppeteer tests. put it before the deploy stage. use a docker image with node and chrome. make sure ur deploy stage only runs if the test stage passes. also, watch out for flaky tests in CI - might need to tweak timeouts. good luck!

I’ve successfully integrated Puppeteer e2e tests into our GitLab CI/CD pipeline. Here’s what worked for us:

We added a new job in our .gitlab-ci.yml file specifically for Puppeteer tests. This job runs in a ‘test’ stage, which precedes the ‘deploy’ stage. We use a Docker image with Node.js and Chrome pre-installed to run the tests headlessly.

Our pipeline structure looks like this:

stages:

  • build
  • test
  • deploy

The key is to make the ‘deploy’ stage dependent on the success of the ‘test’ stage. This way, if Puppeteer tests fail, the deployment won’t proceed.

One challenge we faced was test stability in the CI environment. We solved this by increasing timeouts and adding retry mechanisms for flaky tests. Also, we found it helpful to output detailed logs for failed tests to aid in debugging.

Remember to optimize your tests for CI execution. This might involve tweaking configurations or splitting long-running tests into separate jobs.

I’ve implemented Puppeteer tests in our GitLab CI/CD pipeline, and it’s been a game-changer for our deployment process. Here’s what worked for us:

We created a separate job in our .gitlab-ci.yml file specifically for Puppeteer tests. This job runs in the ‘test’ stage, which comes before our ‘deploy’ stage. We use a Node.js image that includes Chrome, so Puppeteer can run headless tests.

The key is to set up your pipeline stages correctly. We have something like:

stages:

  • build
  • test
  • deploy

Our Puppeteer job is in the ‘test’ stage. If it fails, the pipeline stops automatically, preventing deployment. This setup ensures our e2e tests must pass before any code reaches production.

One tip: Cache your node_modules to speed up the pipeline. Also, consider running your tests in parallel if you have many. It’s drastically reduced our pipeline time.

Hope this helps you get started!
