Code Coverage

Measure how much code is tested

Code coverage shows which lines your tests execute:

jest --coverage

Coverage reports show:

Lines: Percentage of lines executed
Branches: Percentage of if/else branches tested
Functions: Percentage of functions called

Aim for high coverage, but don't chase $100$ %. Focus on testing logic, not every line.
