问题描述
我知道行覆盖率和分支覆盖率有什么区别，但是代码覆盖率和行覆盖率有什么区别？以前的指令覆盖率高吗？
I know what the difference is between line and branch coverage, but what is the difference between code coverage and line coverage? Is the former instruction coverage?
推荐答案
覆盖率是细微的;-)行和分支覆盖率的混合。
Coverage is a subtle ;-) mix of the line and the branch coverage.
您可以在我们的：
coverage = (CT + CF + LC)/(2*B + EL)
where
CT - branches that evaluated to "true" at least once
CF - branches that evaluated to "false" at least once
LC - lines covered (lines_to_cover - uncovered_lines)
B - total number of branches (2*B = conditions_to_cover)
EL - total number of executable lines (lines_to_cover)
