It is a crime to neglect software qa outsourcing as it is a cost-effective and time efficient way to improve quality of software products. It is especially important to realize that sending your project / products to offshore partners for testing will save yourself some of your nerves – you will be busy only with the development process since qa work will be being done by those who have deep knowledge and many years experience in testing field.
The main disadvantage of bottom-up testing is that it requires writing a special code which invokes the module under test. If it is, in turn, invokes another module, it is necessary to write dummy functions (modules) known as drivers and stubs. A driver or stub can simulate the called function, which returns values, but it is the only capability of the test doubles.
It is understood that the process of writing the code as well as test stubs takes long and slows down the work; moreover, the stubs are absolutely useless for the final product. But once written these dummy programs or components can be reused each time when the software undergo changes or modifications. A good set of the codes and test stubs can considerably facilitate qa process as these are very effective testing tools.
In contrast to bottom-up testing, holistic approach to software testing assumes that separate modules of the system can be thoroughly tested only if the system is fully integrated.
By the way, list of software testing companies has helped a lot of app developers because most of them at last have managed to find a highly qualified testing specialist that suit them best.
The advantage of holistic testing strategy is that it does not imply writing an additional code. For this reason, many managers opt for this method just to save testing time – they believe that it is better to develop a one, comprehensive set of tests and use it at a time to test the entire system. But this idea of theirs is absolutely wrong, and here’s why.
It is very difficult to identify the source of the error. This is the main problem with the strategy. Since none of the modules are properly verified, most of them have errors. So it turns out that the thing is not to understand which module contains an error identified, but which of the errors in all the modules involved in the process has caused the problem.
You can be the luckiest person after dealing with testing services companies from Ukraine. Due to their professionalism and workmanship, these are always asked to verify and validate developed software applications. This collaboration may ensure successful launch of your IT products and you will be able to increase your brand reputation!
