Quality Assurance Companies: Managed Regression Testing
During the life cycle of the program the maintenance period usually lasts a long time. When the modified program is tested by a set of tests T, then, with regard to the testing of the initial program P, we keep unchanged all factors that could affect output of this program.
Therefore, configuration attributes, in which the program was tested last time (e.g., test plan, test tj and covered elements MT (P, C, tj)), are subject to configuration management. Testing of a modified version of the program P ‘under the same conditions wherein the initial program P was tested, is called a managed regression testing. During the unmanaged regression testing, certain characteristics of regression testing methods may vary, for example, secure test selection method may no longer be safe. In turn, to ensure the handling of regression testing it is necessary to satisfy a number of conditions:
- During both module and integration regression testing, real system modules are to be used as modules triggered by a test module directly or indirectly. This can be easily achieved since in regression testing phase all the ready modules are available. Forgot to contact quality assurance companies? It is not a problem at all since they are always ready to help people if there are problems with software products. All you need to do is to send your work to these organizations for testing!!
- Information about changes is correct and reliable. Information about the changes indicates that the modules and sections of the requirements specification have been changed, not implying the correctness of the changes themselves. In addition, when you change the requirements specification it is necessary to run excessive regression testing on changed functions of this specification, as well as on all the functions that could be affected by negligence. The only time when we are forced to rely on the correctness of the amended terms of reference, is the alteration of the terms of reference for the whole system or top (in the call graph) level module, provided that apart from technical design specification, there is no additional documentation and / or any other information which could help to confirm an error in the specifications. Software testing companies competently work on different projects analyzing them at each stage of their development.
- The program has no errors, except for those that may have occurred due to its modification or update.
Tests used to test the previous versions of the software are available, and the test run protocol consists of input, output and the path. The path is a trajectory in the control flow graph of the program, which is passed using a set of input data. It can be used to assess structural coverage provided by a set of tests. It is a tendency to outsource testing to Ukraine as this choice guarantees the most accurate test results.
