Pitching Tests at the Right Level
Explore how to choose the appropriate level for unit tests to maximize clarity and test coverage. Understand the trade-offs between writing detailed tests that document specific behaviors and high-level tests that cover broader functionality, enhancing your ability to design effective and maintainable NUnit tests.
Introduction
There are numerous best practices associated with unit testing. For example, one of these is to include one assertion per test if possible. However, other best practices are more subjective. One of these practices is how many test methods to write to determine whether the application code behaves as expected. One approach is to write as many test methods to explicitly test individual, desired behaviors. Another approach is to write fewer test methods that test the functionality as a whole. Although writing fewer test methods is more succinct, this approach comes with the disadvantage of rendering the test cases more difficult to follow. This reduces the effectiveness of the test code as a means of documentation. ...
