This post is a quick look at Black Box Vs White Box Vs Gray testing and the differences between them all.
Black Box Testing
Black box testing is functional testing. It is used to check whether or not software or an application is operating in accordance with specifications. During the first stage of software development, a very straightforward testing procedure is performed. Learning about the QA procedure is beneficial for testing newbies.
Technique Used :
- Decision Table Technique.
- Boundary Value Analysis
- State Transition Technique
- All Pair Testing Technique.
- Cause-Effect Technique.
- Equivalence Partitioning Technique.
- Error Guessing Technique.
- Use Case Technique.
White Box Testing
White box testing includes structural and code testing. It is beneficial to get rid of superfluous lines of code and mistakes. Because programming knowledge is required to carry out white box testing, it is also known as transparent testing, glass box testing, and structural testing. Testing the input and anticipated output of the software is the main objective of white-box testing.
Technique Used :
- Control Flow Testing
- Branch Testing
- Statement Testing
- Decision Testing
Grey box testing
A hybrid of the closed box and glass box testing is known as grey box testing. A basic understanding of an application’s internal workings is required to perform grey box testing. Here, we perform white-box testing, which involves designing test cases using some programming expertise, and black-box testing, which involves designing test cases using a functional understanding of an application.
Instead of concentrating on the developer’s or tester’s perspectives, it emphasizes the viewpoint of the end user.
Technique Used :
- Matrix Testing.
- Regression Testing
Black Box Testing Vs White Box Testing Vs Gray Box Testing
This table compares all three.
Conclusion:
The testing phase of software development is crucial. The testing procedure comes in a variety of forms. Whether it is a Black box, White box, or Gray box need, all testing types are ideal for it.
“We all have our own distinct identities and positive and negative attributes.”
The terms “Black box testing,” “White box testing,” and “Gray box testing” are interchangeable; each has its own qualities as well as advantages and disadvantages.
