What should you test?
In general, you should use WSim to test any significant change to your system. This includes any changes that might affect hardware, system software, application programs, workload, or environment. Ask yourself the following questions about a proposed change:
- How complex is the change?
- How many components will be changed?
- How many transactions or transaction types will be affected by the change?
- How many people will be affected by the change?
- How difficult will backup and recovery be after the change?
- What's my past experience with changes of this type?
The answers to these questions help you decide what types of changes you want to test with WSim.
