Techniques for testing

Techniques for testing

1. Test harnesses

   • Streamline software development
   • Assist with further maintenance
   • Avoid the need for time-consuming manual testing

2. Performance testing

   • Determines how fast some aspects of the system
   • Can compare two systems to see which performs better
   • Can see what performs badly

3. Volume and scalability testing

   • Testing using the anticipated volume of peak data or network traffic
   • Makes sure that systems have adequate storage capacity
   • Also must make sure system has enough processing for vast amounts of data

4. Usability testing

   • Measures how well people can use the system
   • May cause developers to redesign and retest the system

5. Portability testing

   • Systems will be used on a range of different hardware
   • Also used on different operating systems

6. Prototyping

   • Prototypes can be used to define a system
   • Can have digital prototyping or paper prototyping

7. Use of simulated environments

   • Some systems can only be tested on one manufacturer's hardware
   • Emulations and simulated environments can have limitations
