Reliability is about making sure that different test forms in a single administration are equivalent; that retests of a given test are equivalent to the original test, and that test difficulty remains constant year to year. When a student must take a make-up test, for example, the test should be approximately as difficult as the original test.

Code Coverage and Test Automation v5
Test coverage is sometimes used as a proxy for measuring software reliability, in the case that no errors have been found. This application of coverage, though it seems to be intuitively reasonable, is difficult to motivate in a scientifically legitimate way, i.e. the relationship between coverage and reliability is unclear.
