COMPATIBILITY TESTING. Testing to ensure compatibility of 
an application or Web site with different browsers, OSs, 
and hardware platforms. Compatibility testing can be 
performed manually or can be driven by an automated 
functional or regression test suite. 

System testing of software is testing conducted on a 
complete, integrated system to evaluate the system's 
compliance with its specified requirements. System testing 
falls within the scope of black box testing, and as such, 
should require no knowledge of the inner design of the code 
or logic
