I'm currently facing a challenge in adding integration testing to my Angular 10 based application. Locally, everything seems to be running smoothly as I define the tests in files with the spec.ts extension and run them using ng test. However, the real dilemma arises when it comes to running these tests in a production environment. I utilize GitLab CI to dockerize the application and deploy it for production using nginx on Kubernetes. Whenever I access my pod, the built production version is there, rendering the ng test command useless. My main goal is to run tests that are primarily related to my Angular service, involving example requests like POST, GET, DELETE, etc. to other components to ensure the entire system functions properly within the Angular portal. Do you happen to have any suggestions or solutions on how I can overcome this obstacle?
