3.9 Testing Techniques

3.9 Testing Techniques

1. Test Hardness

   • allows some types of testing to be automated
   • consists of software and test data which run code under different conditions
   • removes the need for a programmer to do the same repetetive tests

2. Volume testing

   • to show how the system changes with different volumes of data
   • so it is ensured it can meet the specifiation and requirements of the client
   • establishes the limits of the volume of data a software can handle

3. scalability testing

   • a series of tests are conducted as the system is scaled up
   • results are analysed when the system starts to struggle
   • making sure the system can handle increased workloads

4. prototyping - not strictly a testing type but useful

   • so that required changes can be made
   • producing working but limited versions of the system at various points in the SDLC
   • allows feedback to be collected at various points

5. Portability or multi platform testing

   • used when systems need to operate on multiple platforms such as different operating systems
   • aims to demonstrate that the software can be transferred

6. use of simulated enviroments

   • the tests are done in real situations so that it is as close to the real final system as possible
   • the test conditions are fairer because its how the system will actually be used
