White Box Testing: White Box Testing is a type of Software Testing in which the internal structure, design and implementation of the software application that is being tested is fully known to the tester.
Gray Box Testing: Gray Box Testing is a software testing technique which is a combination of Black Box Testing technique and White Box Testing technique. The internal structure, design and implementation is partially known in Gray Box Testing.
Differences between White Box Testing and Gray Box Testing:
S. No. | White Box Testing | Gray Box Testing |
---|---|---|
1. | It is a type of software testing in which the internal structure and design of the software application is fully known to the tester. | It is a type of software testing in which the internal structure and design of the software application is partially known to the tester. |
2. | It is also known as clear box testing or transparent testing. | It is known as translucent testing. |
3. | It is performed by testers and developers. | It is performed by end users, testers and developers. |
4. | Full knowledge of the implementation is required. | Small knowledge of the implementation is enough. |
5. | High programming skills are required to perform white box testing. | basic programming skills are enough to perform this testing. |
6. | It is a time consuming testing. | It is a less time consuming testing. |
7. | It is used for algorithm testing. | It is not used in algorithm testing. |
8. | As application’s internal working is known to the testers so they prepare test data accordingly and attempt to test nearly every code scenario using these test cases. | High-level data flow diagrams and database flow diagrams serve as the foundation for this testing because they provide the basic required functionality knowledge. |
9. | As major part of this type of testing depends on the internal implemented code so both possibilities exist here- one is automation of this testing and other one is development of algorithms for this testing. | There is less possibility of automation in gray box testing as it does not have access to the internally implemented code. |
10. | It takes more time to design test cases due to lengthy code. | It takes less time in designing test cases. |
11. | The coding form the basis for internal working in this testing. | High-level database diagrams and dataflow diagrams form the basis for testing. |
12. | It is most exhaustive. | It is partially exhaustive and that depends on the type of test cases whether they are coding based or GUI based. |
