Introduction Black box and White box testing

Hello, i will be writing about different between black box and white box testing. before, i believe all understand assign job QA. but, you know different system black box and white box testing ?

Black box testing ?
Testing is based on detailed procedures and logic of the program code. In whitebox testing, the tester looks at the source code of the program and finds bugs from the code of the program being tested. The point is whitebox testing is a test that is carried out to the details of checking program code.

Look at the program code -> make a test case to look for errors / bugs / errors from the code program

White box testing ?
Testing is based on application details such as application appearance, functions in the application, and the suitability of the function flow with the business process desired by the customer. This test does not see and test the program code.
