The majority of software testers in best software testing companies know that theory is crucially important in practice. On one side, beginner testers don’t believe this, but practice shows and confirm that theory should be implemented in practice. Our specialists picked up three the most interesting software testing principles that can be useful in daily work performance.

#1. Pesticide Paradox

The name of this principle was taken from agriculture terminology. Its appearance was caused due to the fact if the developed tests when performing functional testing services revealed no bugs, then tests should be analyzed and depending on the program requirements; testers must create new testing services that would detect bugs.

#2. Testing is Context Dependent

Depending on the program type, its requirements, and implementation, the testing process passes differently. For systems that secure people and data (personal information, corporate and government), testing would be performed more careful and will differ from game testing services or website testing services.

#3. Absence-of-errors Fallacy

The given principle has a weird name, but there is an explanation. If the developed system doesn’t respond customer’s needs and is not suitable for work, it doesn’t matter the number of found defects and their elimination – to use the program doesn’t make sense.

A perfect and bug-less program is that, which haven’t yet written. Testing process helps reduce the likelihood of missing defects that are still in software. Even if testing didn’t detect errors, it doesn’t mean that the product is bug-less.
