Test Coverage is an important indicator of software quality and an essential part of software maintenance. It helps in evaluating the effectiveness of testing by providing data on different coverage items. Although much research effort has been put on how to get coverage information by either code based testing or requirement based testing, not much has been paid to measure and analyze the coverage by covering maximum number of coverage items. This paper provides a study of the current test coverage researches conducted by other researchers for test coverage in software testing.
