The Life Cycle of Defect
The Life Cycle of Defect
To be able to avoid computer locking during test run, it is extremely important for software developers to correct software errors as quickly as possible at the dynamic testing stage. As a rule, locking effects during testing execution are caused by logical errors that prevent the test data from being processed by the corresponding lines of code. In the early dynamic test stages it is quite natural that testers and developers should work in close collaboration with each other, discovering and correcting software errors. But in the final stages of testing, or when larger projects are being developed, the role of coordinator, verifier, and priority setter is performed by the change control review board (CCRB). When the software module is ready for testing, a leading developer starts interacting closely with the software configuration manager (SCM), performing an assembly operations. As a result, an executable version of the software product is created and the source code is updated to the new version. Software quality assurance companies strive to meet quality expectations of different types of clients, finding individual approach to each consumer. Winning your customers’ confidence is easier than you think if you deal with masters of their craft!!
Personnel of the testing team are responsible for setting up the test environment for this executable program, as well as for creating computer systems, operating systems, databases, communication lines, and the like. In addition, this staff chooses a suitable set of test cases. When selecting test cases, the testers consider the nature of program errors, detected by the module, and their location in the code. In accordance with the test scripts, the testing specialist examines the program and sequentially compares the intermediate results with the test results that are documented in the test case. The discrepancy between the actual and the expected results indicates either the need to update the expected results of the test case with actual results, or find another error. After executing the selected set of test cases for the version being created, regression testing is performed to make sure that the recent changes have not destroyed any of the functions that previously worked correctly The characteristics of any new errors are entered in the reliability database and in the problem report, after which the debugging process continues to run.
