Redundancy Detection

ABSTRACT

Test redundancy detection reduces test maintenance costs and also ensures the

integrity of test suites. One of the most widely used approaches for this pur-

pose is based on coverage information. In a recent work, we have shown that

although this information can be useful in detecting redundant tests, it may

suer from large number of false-positive errors, that is, a test case being iden-

tied as redundant while it is really not. In this paper, we propose a semiauto-

mated methodology to derive a reduced test suite from a given test suite, while

keeping the fault detection eectiveness unchanged. To evaluate the methodol-

ogy, we apply the ...
