System Testing
System testing of software or hardware 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.
As a rule, system testing takes, as its input, all of the "integrated" software components that have successfully passed integration testing and also the software system itself integrated with any applicable hardware system(s). The purpose of integration testing is to detect any inconsistencies between the software units that are integrated together (called assemblages) or between any of the assemblages and the hardware. System testing is a more limiting type of testing; it seeks to detect defects both within the "inter-assemblages" and also within the system as a whole.

Testing the whole system
System testing is performed on the entire system in the context of a Functional Requirement Specification(s) (FRS) and/or a System Requirement Specification (SRS). System testing is an investigatory testing phase, where the focus is to have almost a destructive attitude and tests not only the design, but also the behaviour and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds defined in the software/hardware requirements specification(s).

Who do you want to test with?
The people you want to conduct your mobile phone usability testing sessions with will, of course, depend on your particular business and its audience. Some things to bear in mind include:
* How much experience they should have of using their mobile phones to access services. This is particularly important as the market for accessing online services through mobile phones is growing and the percent of 'complete novices' (i.e. people using the technology for the first time) will be far higher than for computer users of your website.
* Which mobile phone or PDA they have. We would usually recommend that people use their own mobile phone in a session, so the test can focus on your website and not on the way the handheld device works.
