Most of todays automated tests are deeply database dependent. You probably know them. Those tests where a lot of data creation is done before you get to execute the action under test. The thing with them is that they both take a lot of time to build and a lot of time to run.

With the principles of SOLID, inspired by Vjeko, we have restructured the logic of the code in a way that isolates and abstracts it. This makes the tests run lightning fast because it’s no longer dependent on any data from Business Central. And next this: by applying this approach we attain less dependency on breaking changes.

This coupled with a revised test plan ensures a more stable and better testable code yielding a better result in the end.
