Quality Assurance Organizations: Classification of Tests
Quality assurance organizations tend to find all possible defects in software apps before these are made available to the target audience. You have the chance to run any test on your IT product / project to make sure that it is consistent and safe.
Classification of tests with respect to changes in the code requires an analysis of the effects of the changes. Tests that redeem the code affected by the changes may need to be rerun or appear to be obsolete. A test can be included in a class of tests which should be re-executed, if it has been affected by changes in the code, and also helps to increase the degree of coverage of the amended code based on the criterion used.
The affected element of the test can be a test path, the output value, or a combination of both. To be included in a class of reusable tests, a test should contribute to increasing the degree of code coverage and not want rerunning.
A degree of code coverage is determined for the tests that are suitable for reuse, since this test class includes the tests that do not need to be done repeatedly and promote an increase in the degree of coverage to the desired value. If there is a component of the program, not affected by reusable tests, then instead of them, so that to increase the coverage, you should select and run tests which need to be re-executed. After the run, this test becomes suitable for reuse or turns to be obsolete. If there are no tests that should be repeated, and the necessary degree of code coverage has not been achieved, additional tests are generated and testing is redone.
Quality control consultants will advise you on the most important factors affecting successful software development. Do you want to increase your sales and meet customer demands? If so, do not be in a rush to release ready software without testing it as good as possible. It may contain bugs which will cause it to malfunction.
The final set of tests is gathered from tests that are suitable for reuse, tests that need to be performed again, and new tests. Finally, obsolete and redundant tests are removed from the test set as redundant tests neither analyze new functionality, nor increase coverage.
Therefore, it is necessary to focus on the selection of only those tests that cover the modified code, affecting, in turn, the program’s output. This approach allows you to select only those tests that detect changes, and the method will be, as they say, exact. Quality assured services should be necessarily used in earlier phases of software development as then it would be cheaper to fix bugs than when the development comes to its end.
