Unit Testing: Myth Busting

No matter how often  unit testing is conducted, there are still numerous stereotypes connected to this type of software testing.

As an experienced software testing company, we want to bust the existing myths.

Myth 1: Testing of a separate component can be performed only once and later on it may be reused.

Reality: A separate software component should undergo testing every time it is used in a new environment. You can’t be 100% sure that the component will work the same in every possible context, so in this case software testing is a must.

Myth 2: If the developers have already performed software testing, then it doesn’t need additional verification.

Reality: Developers are usually too busy to perform ground testing of the software that would cover various aspects of the software work. Besides, the closer the release time is, the more work they seem to have. Thus they only perform general verification of the software’s work. On the contrary, a good software testing company can perform detailed check of the offered software performing various types of software testing (be it mobile testing, web site testing or any other type).

Myth 3: It is enough for developers to perform unit testing when creating the software in order to make it work good.

Reality: Double-checking is never extra. In the process of its development, software undergoes various changes and should be checked through all the process.

Myth 4: Component testing that is performed by developers in component-based software engineering (CBSE) is the same as unit testing performed by software testers.

Reality: These types of software testing though quite similar have a number of differences, the main of which is their focusing on various objects. The developers are more concerned with components’ work and their functions, while testers are considering everything from the point of view of the end-user.
