How does code coverage work? Code coverage is performed to verify the extent to which the code has been executed. Code coverage tools use static instrumentation in which statements monitoring code execution are inserted at necessary junctures in the code.

What is acceptable code coverage?

Code coverage of 70-80% is a reasonable goal for system test of most projects with most coverage metrics. Use a higher goal for projects specifically organized for high testability or that have high failure costs. Minimum code coverage for unit testing can be 10-20% higher than for system testing.

How do you get 100 percent code coverage?

2 comments
One of the steps into achieving the 100% coverage rule is to start with a better design. E.g. many times setter and getters are considered trivial to test and thereby causing people to skip testing them and thus lowering the coverage.
Agreed, the best way to improve coverage is to write less code.

(B) the number of lines of code all test cases currently execute, and.
Find (B divided by A) multiplied by 100 – this will be your test coverage %.
