| 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. | | Here, the basis of testing is the external BEHAVIOR of the software. | Here the basis of testing is purely internal behavior of the software. | Here the testing is based on high-level databases and data flow diagrams. |

| This comprises checking the documents, codes, designs, and programs. | This comprises the testing and checking of the actual product. | | This is basically static testing. | This is dynamic testing. | | This does not include the process of executing codes. | This does include the process of executing codes. | | It contains various types, such as reviews, walkthroughs, desk-checking, and inspections. | It includes three types of processes, namely, non-functional testing, Black Box Testing, and White Box Testing. | | This process EXAMINES whether a software conforms to specifications or not. | This process examines whether the software meets the expectations and requirements of a user. | | It is used to find bugs in the early stage of inspection in any software. | Used to find out bugs not found by the process of verification. |
