Part 3 – Non-Functional Testing

Once the functional testing is complete, you can be confident that the feature under test will work as designed. But there is still more to check – what is the maximum load this feature can sustain? If there is an outage, how does the system behave, and how does it recover? Under load, are all features still available? This section considers the usage of the feature under extreme conditions, how to generate that load and the tests that should be run.

This section comprises the following chapters:

• Chapter 11, Destructive Testing
• Chapter 12, Load Testing
• Chapter 13, Stress Testing
