Sonar-Overall Coverage

Question

Sonar gives a value of Overall coverage which is a combination of line and branch coverage. I am not sure how important is this metric. What does the value of overall covera

Answer 1

From Sonar's documentation:

It is a mix of Line coverage and Condition coverage. Its goal is to provide an even more accurate answer to the following question: How much of the source code has been covered by the unit tests?

Coverage = (CT + CF + LC)/(2*B + EL)

where

CT = conditions that have been evaluated to 'true' at least once
CF = conditions that have been evaluated to 'false' at least once
LC = covered lines = lines_to_cover - uncovered_lines

B = total number of conditions
EL = total number of executable lines (lines_to_cover)
