This is also known as functional testing, data-driven testing, and closed-box testing. | Also known as structural testing, precise box testing, code-based testing, and transparent testing. | Also known as translucent testing. |
It is not suited for algorithm testing. | It is perfectly suitable and recommended for algorithm testing. | Not considered for algorithm testing. |
This kind of testing is based on a trial and error system as the tester does not have coding knowledge. | This type of testing takes an approach of verifying the system boundaries and data domains inherent in the software. | If the tester has enough knowledge of coding, the way forward is validation data domains and internal system boundaries of the software. |
The testing space of tables for inputs is the largest among all the other testing processes. | The testing space of tables for inputs is less as compared to Black Box testing. | The testing space of tables for inputs is the least. |
In this, the user, tester, and developer can be a part of the testing process. | In this, only the tester and developer can be a part of the testing process. | In this, the user, tester, and developer are part of the testing process. |
