Building a Weather Application From Scratch
Exposing Gaps in the Test Suite
The interface of the
RootViewModel class shows that we only need to unit test the initializer and the
refresh() method. I explained earlier why I don't unit test the initializer and, in the previous episodes, we unit tested the
refresh() method. Does that mean that the test suite now completely covers the
RootViewModel class? The answer is no. This is a common mistake developers make. In this episode, we collect code coverage data to expose the gaps in the test suite.
