4‌ ‌black-box‌ ‌testing‌ ‌techniques‌ ‌for‌ ‌your‌ ‌project‌ ‌ ‌

A working principle of black-box testing is similar to its name. Testers are interested in data input and output, excluding internal program structure.  

For engineers, a program code, design, and internal structures are a black box in which testing is not conducted.   

 The main goal of black-box testing is checking the whole system in the presence of external factors that lead to failures. Also, black-box testing covers performance and usability issues, functionality from the user's perspective, the system's interaction with the inputs, etc.  

There is no need to know any programming language to conduct this test, so it is a huge benefit for beginners. Among other advantages are independence between developers and testers, test cases can be designed as soon as software functional specifications are complete, acceptance for a large system.  

On the other hand, a beginner's lack of technical knowledge can lead to an omission of possible test cases to be tested. Test cases writing may be a long and problematic process due to complications identifying inputting data caused by limited testing time.    

Let's consider the best black-boxing testing techniques which are perfect for professional testers and your QA company.

 

Equivalent Class Partitioning 

The benefit of this technique is reducing the testing time as a consequence of split off test cases on groups and modules. In this technique, input values are separated into classes and groups according to their similarity. So instead of inputting every particular value, we can use any value of the group to test to get results.
