What is White Box Testing?

In this video I am showing test methodologies.
There is three types of testing methodologies
White box testing?
Black box testing?
Grey box testing?

White Box:
White box testing means conducts on internal logic of the programs.
For Example: Developers have created some programs.
He has to test these programs by QA
So if QA provides proper input and write input. it’s giving expected output or not.
exactly that QA has to verify, because the program itself returned by him.

So White box testing means QA needs to conduct a testing on internal logic it’s currectly or not, by providing multiple types of inputs.

If you want to perform white box testing you need programming skills. Because until you don't know the programming you can not understand loops and conditional statements. The major part of the testing will be focus on loops and condition

So we need conducts testing are programing level so if you want to do this you need to know about programmings

So White box testing is conducted on internal logic of programs and if you want to perform white box testing you need to know about programming.

Unit testing and integration testing is part of white box testing. Because unit testing and integration testing test the internal logic of a program.
