How to Detect Bugs in a New System Version?

Very often software testing company compares the results of checking of the same product aspects but of different system versions. It helps to define a large amount of errors.

To effectively perform mobile testing, web programs checking or software products testing, it is necessary to choose the input data that will suite all system versions under test. Moreover, it should be convenient to compare the results of such inputs. But such an approach is rather time-consuming and it requires some effort. That is why this practice is often automated.

What Should Be Considered During the Automation of Several System Versions?

• The testing tools can be either bought or developed by the team itself. The pros and cons of both ways should be analyzed in order to make the right choice.
• It is better to have the test cases written before automated testing actually begins. Besides that, their number should be enough to fully cover all system aspects.

But in some cases – when the system is too complicated and complex – the amount of possible test cases is huge. And to execute all these tests will only be a time-wasting. Fortunately, there are some methods that help to define the number of most suitable test cases, and as a result web testing or mobile apps checking will be efficient.

What Are the Methods of Choosing the Most Relevant Tests?

• Orthogonal array testing
• Cause-effect graphing
• Boundary value testing
• Equivalence class testing
