如何计算Code Coverage

learn.whatIsHeading

A code coverage calculator determines the percentage of codebase lines, branches, or functions executed by tests. Coverage = (tested lines ÷ total lines) × 100. Most teams target 70–80% coverage; 100% coverage is neither practical nor sufficient for quality assurance.
