QA Outsourcing – The Right Way to Run Black Box Testing
When coding phase is completed, testing phase begins – the program goes to a testing group for analysis. The testers seek out high and low value defects, write bug / defect reports, then receive a new version of the program and set out to find defects in it over again. They identify the defects that were missed in the first stage, and the new ones, which were introduced in the program after it underwent modifications.
QA outsourcing service is famous for its benefits such as cost-effectiveness, independent verification & validation, increased software quality, decreased defects, improved customer satisfaction, trained and certified specialists and so on and on…
Here’s how Martin & McClure gave a summary of the information about effective defect management, which was gathered by Boehm.
- If there is a need to change up to a dozen of operators in order to correct a program defect, the likelihood that it will be done right the first time is 50%.
- If there is a need to change about fifty operators in order to correct a program defect, the likelihood that it will be done right the first time is only 20%.
The problem is not only that the programmer cannot repair a defect completely. Things could get a good deal worse – the corrections may involve unpleasant consequences. Repairing one defect may cause another defect to occur. And also it happens that one defect hides another defect, which manifests itself only after the first one has been corrected. Unfortunately, programmers often focus only on the problem put before them and after solving it they decide that they are done with their work and, as result, they do not conduct regression testing, even in a superficial manner. Regression tests play important role in the development process.
Also, it is necessary to load test the apps throughout the entire development process to ensure their best quality. Nobody but professionals of load testing companies are able to understand that a program or a certain function can handle what it is intended to handle. By subjecting the software being tested to simulated demand they can determine how well it can deal with real workloads it is most likely to encounter through systematic use.
Given all the above, get yourself ready to test one and the same program multiple times. In the early testing stages the modified versions of the program may be submitted to test every few hours or days. Accordingly, the experts tend not to accept the new version until the previous version has been thoroughly tested. Such comprehensive testing of the earlier version along with generation of final defect report describing all the problems with this version is called the full testing cycle.
Top software testing companies are the best providers of software testing and quality assurance services. They perform testing of the products on all development life cycle stages.
