Your GitLab's C.I. stop after run all tests? Because you are using "singleRun: false", how to deal with this? Can you share your gitlab-ci.yml too?

@brunoocasali
You can override this singlerun via the CLI. For example:

ng test --browsers ChromeHeadless --single-run=true

This means that the singleRun boolean in the karma.conf.js file can stay on false. (or visa versa if you like)
