Reasonability to Outsource QA When It Comes to Configuration Testing
Configuration testing involves testing of the program with all possible numerous combinations of hardware and software to determine the optimal configurations which the system can work without any flaws or defects. It is better to outsource qa needs of yours to third party partners if you strive to reduce development costs and risk of losses that usually result from failure of software apps.
Despite the fact that thoroughness matters much while performing configuration testing, even simple calculations indicate that no one is able to thoroughly examine the program to understand how it will interact with all possible environment settings.
And what will happen if you check the program for compatibility with positioning devices? For example, if you select 10 most popular video cards and the five most popular mouse models, you will have 50 tests to run. Now, add the three drivers per each mouse – and this time you will have to run 150 tests. Monitors also differ from each other, therefore you should first test the two main types – monochrome and color ones. Video boards drive them in different ways. So if there is a need to test also two basic types of monitors, it will result in 300 tests.
Preferring QA outsourcing service over in-house quality assurance service you will save on your expenses. Besides, when dealing with offshore specialists you get access to talent pool and variety of resources required for ensuring desirable quality of the products.
As you can see, with each new test object to be added to the process, the total number of tests is growing exponentially. Even if you select only a few of the most popular models of the major external devices how will you deal with an endless variety of the others?
To properly plan and perform the configuration testing, you need to have a lot of knowledge. First of all, you should find out what the function of each of the devices is used in the program, and how to understand that the program uses them correctly. It is important to know everything about the compatibility or incompatibility of these devices and how their differences can affect the program being tested by you. If you find out which of the devices can emulate each other, you can save time and money by testing a single representative from each group of compatible devices, one at a time.
Thus, the devices must not be 100 % compatible – if the functions used by your program work in a similar way – that is enough. However, when classifying the devices based on the degree of their compatibility, you should be careful: do not trust the claims of their manufacturers.
