GitLab CI is a tool that is built into GitLab. It is one of the best CI/CD tools since it offers various features like code reviews, CI/CD, continuous deployment, and more within a single dashboard.

For using GitLab CI/CD, you need to host the codebase in a Git repository and specify the scripts for performing a build, test, and deployment in a YAML file named .gitlab-ci.yml, which should be present in the root directory. The scripts are grouped into jobs and are referred to as a pipeline. The GitLab runner tool detects the scripts and runs the same.

You can also Subscribe to the LambdaTest YouTube Channel and stay updated with the latest tutorials around Selenium testing, Cypress E2E testing, CI/CD, and more.

Salient Features of GitLab CI
