🐛 Code Coverage: Coverage value shown for folders in the File Explorer doesn't match line coverage

[ChrisVandoo]

Plugin Name

code-coverage

📜 Description

The coverage value shown in the File Explorer for folders doesn't match the line coverage value.

👍 Expected behavior

The coverage value reported for a folder should match ( total lines - missed lines)/total lines.

👎 Actual Behavior with Screenshots

In this case, the reported coverage for a top level directory was 67%.

However with 426 missed lines and 1492 tracked lines, we should have coverage of 1066/1492*100 = 71%

👟 Reproduction steps

• setup Backstage/ configure the code coverage plugin
• upload an lcov coverage report for a component with multiple files of differing lengths Example:

internal/ 
-- main.go (ex. 50 lines, 40 lines covered)
-- main_test.go
-- helper.go (ex. 200 lines, 50 lines covered)
-- helper_test.go

📃 Provide the context for the Bug.

Trying to avoid developer confusion when code coverage values don't line up as expected. Especially noticeable when looking at the root of a component and comparing with the line coverage value in the History tab.
