How can I set up automated testing in GitLab CI?

To set up automated testing in GitLab CI, you need to define a .gitlab-ci.yml file in your repository.

What should I include in the .gitlab-ci.yml file?

You should include stages, jobs, and scripts for your tests. For example, you can define a 'test' job under the 'test' stage.

Can you give me an example of a test job?

Sure! Here's a simple example:

stages:
  - test

test_job:
  stage: test
  script:
    - echo "Running tests..."
    - npm test

How do I run tests on different environments?

You can define multiple jobs for different environments and use the only or except keywords to control when they run.
