Test Coverage

Test Coverage is an important measure of quality for software systems. Test Coverage analysis is the process of:

· Finding areas of a program not exercised by a set of test cases,
· Creating additional test cases to increase coverage, and
· Determining a quantitative measure of code coverage, which is an indirect measure of quality.

Also an optional aspect of test coverage analysis is:

· Identifying redundant test cases that do not increase coverage.

Test coverage analysis is sometimes called code coverage analysis. The two terms are synonymous. The academic world more often uses the term "test coverage" while practitioners more often use "code coverage".
