Time-consuming – Testing can take a significant amount of time, particularly if thorough testing is performed. Resource-intensive – Testing requires specialized skills and resources, which can be expensive. Limited coverage – Testing can only reveal defects that are present in the test cases, and it is possible for defects to be missed.

There are certain limitations of testing in software testing that need to be considered such as incomplete test coverage, the presence of undetectable errors, time and resource constraints, reliance on test data, and the inability to guarantee absolute correctness.

Software testing can ensure that defects are present but it can not prove that software is defect-free. Even multiple tests can never ensure that software is 100% bug-free. Testing can reduce the number of defects but not remove all defects.

Most testing types are time-consuming due to executing tests continuously. Thus, the failing tests should repeatedly run until fixing all the issues. Lack of experienced software and QA testers who are aware of testing techniques. The software testing team requires many members. Increases the cost of the software and the budget.
