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 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 limited type of testing; it seeks to detect defects both within the “inter-assemblages” and also within the system as a whole.

Types of tests to include in system testing

The following examples are different types of testing that should be considered during System testing:

• Graphical user interface testing
• Usability testing
• Software performance testing
• Compatibility testing
• Exception handling
• Load testing
• Volume testing
• Stress testing
• Security testing
• Scalability testing
• Sanity testing</a
