Running tests locally
The previous chapter covered development workflows and Continuous Delivery pipelines. It's crucial for modern enterprise applications to define an effective pipeline. However, while the CI server takes care of all build, test, and deploy steps, software engineers are still required to build and test on their local environments.
Continuous Delivery pipelines with proper tests sufficiently verify that enterprise applications work as expected. However, the shortcoming with only relying on the pipeline is that engineers receive feedback later and only after they have pushed their changes to the central repository. Whereas this is the idea behind Continuous Integration, developers still want certainty in their changes before committing them.
Committing changes that contain careless mistakes disturbs other team members by unnecessarily breaking the build. Errors that are easy to detect can be prevented by verifying the commit locally. This is certainly doable in code level...
