3.8.2 Stages of Testing (M.I.F.S.U.O)

1. 1. Module Testing

   • testing the individual sections of the software to make sure that each section works as intended
   • an example of white box testing ("checks the details of the processing code and algorithms"

2. 2. Integration Testing

   • where the modules are combined one at a time at each integration stage and debugged
   • Debugging: "the process of testing program code to isolate and remove errors"

3. 3. Functional Testing

   • testing the operation of the system and may pick up errors
   • indicates that the solution is likely to to meet its user requirements specification
   • an example of black box testing ("checks that a given input produces the correct output, rather than the details of the processing involved")

4. 4. Systems Testing

   • it checks that all the modules operate together properly
   • checks that a transaction is processed correctly throughout the system from beginning to end

5. 5. User Testing

   • the users of the system will offer their comments
   • testing the user documentation is important

6. 6. Operational Testing

   • conducted in the actual or simulated environment
   • using a simulated environment gives the testers more control over the conditions the solution experiences
