We define Transaction testing as measuring response times for certain actions on a Web page. This may include running simultaneous users to simulate load to see how it would perform or measure degradation.
We define Stress Testing as measuring the systems ability to handle large numbers of transactions during peak periods.
My question is this: Are these the same test from an execution standpoint, but different due to the different objectives that they satisfy??
Stress tests may run higher user counts, but that would just make Transaction test run a subset of Stress tests.
