Changed Code Coverage
Changed code coverage allows you to focus on the test coverage of your code changes.
Calculation Logic
- Use git diff to get
added linesanddeleted linesfor each file - Traverse through the file’s coverage data, checking if
added linesare covered inall dimensions - Calculate the changed code coverage for a single file. Formula:
(number of added lines - number of uncovered lines) / number of added lines
💡
Tip
Many of the added lines do not belong to any of the branches, functions, or statements categories, but they are included in the calculation and are considered covered by default.
