What is a Black Box Testing?
In Black-box testing, a programmer/tester does not have any knowledge about the internal working system of software. This testing is a high level of testing that focuses on the behaviour of the working software. Black-box testing involves testing from an end-user perspective. It can be enforced to virtually every level of software testing: system, unit, integration, and acceptance. This testing is also called closed testing.
Types of Black Box Testing are Functional Testing, Non-functional testing, and Regression Testing.
What is White Box Testing?
White-box testing is a technique that checks the internal functioning of the given system. This testing is based on the coverage of code statements, branches, and conditions. It is considered to be low-level testing. White-box testing is also called a clear box, glass box, and transparent box testing. This white-box Testing method considers that the path of the logic in a program is known already.
Types of White Box Testing are Path Testing, Loop Testing, and Condition testing.
Difference Between Black Box Testing vs White Box Testing?
As we have already seen a brief introduction to Black Box Testing vs White Box Testing. We will now look into and discuss the difference between Black Box Testing vs White Box Testing. The crucial differences between these two test methods are explained in the table provided below:
Difference Between Black Box Testing vs White Box Testing
Black Box Testing
White Box Testing
In this testing method, the programming code of the software is hidden and nothing is known about it.
In this testing method, the programmer or tester must have knowledge about the internal programming code of the software.
Black Box Testing is mostly done by software testers.
White Box Testing is mostly done by developers.
No knowledge of implementation is necessary.
Knowledge of implementation is necessary.
This testing method can be referred to as the outer or external software testing method.
This testing method is the inner or the internal software testing method.
This test is a functional test of the software.
This test is a structural test of the software.
This testing method can be initiated on the basis of the requirement specifications document.
This type of testing method of software is started after a detailed design document.
For this testing method, no knowledge of programming is mandatory.
For this testing method, the knowledge of programming is mandatory.
This testing is the behaviour testing of the software.
this testing is the logic testing of the software.
This testing is higher levels of software testing.
This testing is applicable to the lower levels of software testing.
This testing is also known as closed testing and it consumes the least time.
This testing is also known as clear box testing and it consumes the most time.
Black Box Testing is not suitable for algorithm testing and it can be done by trial, error ways, and methods.
White Box Testing is suitable for algorithm testing and domains of data along with inner boundaries can be better tested.
Searching something on google by using keywords is an example of Black Box Testing.
By input to check and verify loops is an example of White Box Testing.
