Differences between Black Box Testing vs White Box Testing
Software Testing can be majorly classified into two categories:
- Black Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is not known to the tester
- White Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester.
Differences between Black Box Testing vs White Box Testing:
| Black Box Testing | White Box Testing |
|---|---|
| It is a way of software testing in which the internal structure or the program or the code is hidden and nothing is known about it. | It is a way of testing the software in which the tester has knowledge about the internal structure or the code or the program of the software. |
| It is mostly done by software testers. | It is mostly done by software developers. |
| No knowledge of implementation is needed. | Knowledge of implementation is required. |
| It can be referred as outer or external software testing. | It is the inner or the internal software testing. |
| It is functional test of the software. | It is structural test of the software. |
| This testing can be initiated on the basis of requirement specifications document. | This type of testing of software is started after detail design document. |
| No knowledge of programming is required. | It is mandatory to have knowledge of programming. |
| It is the behavior testing of the software. | It is the logic testing of the software. |
| It is applicable to the higher levels of testing of software. | It is generally applicable to the lower levels of software testing. |
| It is also called closed testing. | It is also called as clear box testing. |
| It is least time consuming. | It is most time consuming. |
| It is not suitable or preferred for algorithm testing. | It is suitable for algorithm testing. |
| Can be done by trial and error ways and methods. | Data domains along with inner or internal boundaries can be better tested. |
| Example: search something on google by using keywords | Example: by input to check and verify loops |
