Software Testing and Quality Assurance

• Dynamic white box testing approach greatly reduces the process of testing by providing the inside
information about, what needs to be tested in a software.

• This approach helps the software tester to remove redundant test cases and adds the required test
cases appropriately, thus improving the effectiveness of testing.
• Practice and experience as to what to test, when to test and how to test helps a software tester to
become a good tester.
