Abstract
Evaluating a test suite that contains redundant test cases is necessary
to reduce the cost of testing. The redundant test cases exist when both
of the two test cases are executed the same lines of code. This research
evaluates the test suite by identifying redundant test cases. Exact match
approach is used to investigate the redundant test cases in the test suite.
The redundancy score is defined by redundancy formula which is calculated
by dividing the number of redundant test cases by numbers of test cases
in a test suite. The experiment uses two Java programs. The redundancy
scores of the two test suites from each program are 0.37 and 0.67, respectively.
It means 37% and 67% redundant test cases are included in the test suites.
The redundancy score provides useful information to improve the efficiency
of software testing, especially in testing other programs by reusing the
same test suite such as regression testing and automated testing.
