Examining coverage data line by line

If you double-click a source file or function within a session, the IDE opens the corresponding file in the editor and displays markers to show line-by-line coverage.

The left margin shows the coverage by displaying a green checkmark for each fully covered line, a red X for each line not covered, and a yellow ball for each partially covered line or block of collapsed code.

The right margin displays color bars to show line coverage. Because the right margin does not scroll with the rest of the file display, you can use these color bars to quickly locate areas of the file with partial coverage or no coverage (by aligning the scrollbar with the yellow or red bars).
