What is the difference between white box GREY boy and black box testing?
While black-box testers make sure everything is fine with interfaces and functionality, and white-box testers dig into the internal structure and fix the source code of the software, grey-box testing deals with both at the same time in a non-intrusive manner.
What is the difference between black box testing and functional testing?
Black box testing can check additional aspects of the software, beyond features and functionality. A non-functional test does not check “if” the software can perform a specific action but “how” it performs that action. Black box tests can uncover if software is: Usable and easy to understand for its users.
What is white box testing example?

Can a tester see the AUT?
In simple terms, a tester can only see the actions of the AUT. The tester need not know how those actions are performed. Example: A simple example of black-box testing is a TV (Television). As a user, we watch the TV but we don’t need the knowledge of how the TV is built and how it works, etc.
What is white box testing?
The White box testing is a type of testing in which only internal structures or workings of an application is tested. It is usually performed by the team members who know the code, usually developer. Since the developers have an in-depth understanding of the project code, they are capable of making the changes in the source code easily and in a small time. In White box testing, a tester needs to have a good understanding of the code so that he/she can exercise different code paths using tests.
Why White Box Testing Performed?
White box tests are mainly used to detect logical errors in the program code. These tests focus on individual code units for e.g. classes. modules or subsystems.
Why Black Box testing?
Black Box testing tests by using both valid and invalid input from the customer and gives the desired output or the error message which ensures that the application works properly in both positive and negative conditions.
Why is it easier to create test cases?
