You can run a unit test suite to validate rule functionality by comparing the expected value to the output produced by running the rule. Test cases are run in the order in which they appear in the suite.
In the header of Dev Studio, click.
Select the check box for each test suite that you want to run.
Click Run selected. The test cases run, and the Result column is updated with the result, which you can click to open test results.
You can stop the test run by clicking Stop test execution.
