Testing the Exception Handling Application Block
The tests for the Exception Handling Block use different handlers. Table 15 lists the
scenarios for the Exception Handling Application Block. Here is an explanation of
each of the columns:
●
●
●
ID. This column lists the ID number for each scenario.
Scenario. This column lists the Exception Handling Application Block scenario
being tested.
Users. This column lists the different numbers of users that the tests simulated.
Table 15: Exception Handling Application Block Scenarios
ID Scenario Users
1 Process an exception without handlers. 1, 5, 10, 50
2 Process an exception with the Wrap handler. 1, 5, 10, 50
3 Process an exception with the Replace handler. 1, 5, 10, 50
4 Process an exception with the Logging handler. 1, 5, 10, 50
5 Process an exception with the Replace and Logging
handlers.
1, 5, 10, 50
Creating the Test Harness
For an example of how to create a test harness, see Building Test Harnesses. Iterations
of the test should create an Exception object. For an example of how to create a
domain object for each iteration, see Using the Test Script. In addition, the application
block should handle and rethrow the exception for each iteration. Create a Web
page to run the test harness.
