Silent (indistinct) could be hiding in those untested parts. That's why it's important to understand how much of your code is actually being tested. Measuring coverage helps you identify the gaps, so you're not just writing tests, but writing the right tests. In order to achieve these, we need to set up code coverage reports using Vitest. Code coverage is a critical part of testing, because it helps us understand how much of our code base is being tested and identify areas that need more attention.
