Summary

This chapter covered automated testing, such as unit and integration tests. We also briefly covered end-to-end tests, but covering that in only a few pages is impossible. Nonetheless, how to write integration tests can also be used for end-to-end testing, especially in the REST API space.We explored different testing approaches from a bird’s eye view, tackled technical debt, and explored multiple testing techniques like black-box, white-box, and grey-box testing. We also peaked at a few formal ways to choose the values to test, like equivalence partitioning and boundary value analysis.We then looked at xUnit, the testing framework used throughout the book, and a way of organizing tests. We explored ways to pick the correct type of test and some guidelines about choosing the right quantity for each kind of test. Then we saw how easy it is to test our ASP.NET Core web applications by running it in memory. Finally, we explored high-level concepts that should guide you in writing...
