We verify that the correct changes are found from the database. These seem like easy tasks. However, it is very easy to mess things […] Read more

When we write unit tests that use mock objects, we follow these steps: Configure the behavior of our mock objects. Invoke the tested method.

These rules are obvious. That is why it is surprising that some developers break them (I have broken them too […] Read more
