Planning for web service performance testing
As with any types of testing, performance testing must also be planned properly in order to achieve the correct results. Web service performance test planning can be described in a set of steps, as follows:
Identify the expected performance requirements
Study the service contract
Analyze service integration scenarios
Identify message volume, size, and transmission rate
The expected performance requirements can be specific to your needs. For example, your SLA of a web service includes a phrase stating that the published web service must serve the consumer within 5 ms at peak hours, or the service should be available (up and running) 99.99 percent of the time. Depending on the SLA, you should plan for what types of performance tests need to be done. If the SLA defines 99.99 percent up time, you must plan for a sufficient round of endurance tests to make sure there are no memory leaks or threading issues when the service runs over a long period.
