Question: What are the roles of glass-box and black-box testing tools?
Answer: Black-box testing: It is not based on knowledge of internal design or code.Tests are based on requirements and functionality.
Black box testing is used to find the errors in the following
1) Interface errors
2) Performance errors
3) Initialization errors
4) Incorrect or missing functionality
5) Errors while accessing external database
Glass-box testing: It is based on internal design of an application code.Tests are based on path coverage,branch coverage,statement coverage. It is also known as White Box testing.
White box test cases can check for..
1) All independent paths with in a modules are executed atleast once
2) Execute all loops
3) Exercise all logical decisions
4) Exercise internal data structure to ensure their validity

Black bix testing: Testing the functional and non functional charactristics ( like realibity, portability,maintainability), by refering to test basis ( requirement or design specification) with out reference to the code or structure. Models or texts are the basis of functional testing. Non-functional characteristics are quantified in terms of responce times or Mean time between failures or Mean time to repair.
White box testing is the method of testing the funcational and non functional characteristcs with refrence to internal structure or code. Source: CoolInterview.com
