Why does the 'Test Results' summary page report show that I have unique coverage, when the source page shows no unique coverage?

Q: Why does the 'Test Results' summary page report show that I have unique coverage, when the source page shows no unique coverage?

The source view only shows unique coverage aggregated at the line level, not per statement or branch. The unique coverage indicates that either:

  • the test was the only one to follow a particular path through a branch; or
  • the test uniquely covered a statement on a line containing more than one statement.


(info) Unique coverage is indicated by color-coding.
