You can create an assertion for the expected run time of a data page execution. The expected run time assertion is less than or equal to a number of time you specify, in seconds.
An actual run time that is significantly longer than the expected run time can indicate an issue. For example, if you are using a report definition to obtain initial values from a database, there may be a connectivity issue between the application and the database.
After you create a data page unit test and click either the Create and open or Create and close button, the system generates the expected run time assertion. The default value is the time taken by the data page to fetch results when the test was first run. The system compares that time against the run time of future tests. You can change this value or create additional assertions.
