Identifying and Scripting the Business-Critical Transactions

The core of any performance test is the transactions that drive the load. A simple example of a transaction is logging in to the application, navigating to the search page, executing a search, and then logging out again. You need to determine the high-volume, mission-critical activities that an average user will carry out during a normal working day. These will form the basis of all your performance tests, so you must be sure that you have identified them correctly.

Don’t confuse the key activities in performance testing with functional testing use cases. Remember that your aim is not to test the application functionality (you should have already done that) but to create a realistic load to stress the application and then assess its response behavior from a performance perspective. This should reveal any problems that are a result of concurrency or a lack of adequate capacity.
