Techniques for Testing

Techniques for Testing

1. Test Harness

   • Used to streamline software development
     • And possibly assist future maintenance
   • Consists of predefined software
     • With expected test results
       • Helps to see if changes that have been made are successful
         • Reduces the needs for manual time consuming testing

2. Performance Testing

   • To test how fast some aspect of the system...
     • ...performs under a particular workload
   • Can help to demonstrate how well a system meets performance criteria

3. Volume testing and scalability testing

   • Uses anticipated peak volumes of data input or network traffic and is necessary to test the performance
     • Replicates live conditions
     • Shows how a system will cope as a database would grow, or a website gets busy

4. Usability testing

   • Used for measuring how well people can use an ICT system or part of a system for its intended purpose.
     • Shows if developers need to change the system so users are able to use the system

5. Multi-platform/portability testing

   • Some systems will be used on a range of different hardware and operating system platforms.
     • While it should work on all types of hardware and software this test can highlight problems

6. Prototyping

   • Where prototypes have been used to define (and possibly to sign off) the system, the outputs and appearance of the completed system can be compared with the prototype system.
