Testing your application within the CD pipeline

Until now, we’ve deployed our application on a Kubernetes cluster and manually verified that it is running. We have two options moving forward: either proceed with manual testing or create automated tests, also known as a test suite. While manual testing is the traditional approach, DevOps heavily emphasizes automating tests to integrate them into your CD pipeline. This way, we can eliminate many repetitive tasks, often called toil.

We’ve developed a Python-based integration test suite for our application, covering various scenarios. One significant advantage of this test suite is that it treats the application as a black box. It remains unaware of how the application is implemented, focusing solely on simulating end user interactions. This approach provides valuable insights into the application’s functional aspects.

Furthermore, since this is an integration test, it assesses the entire application as a cohesive...
