Specifies a value that can be used to determine which permission sets are used on tests that are run by test codunits or test functions.
Test codeunits are codeunits that have the SubType property set to Test.
Test functions are functions that have the FunctionType property set to Test.
The property has the following values:
InheritFromTestCodunit is only relevant for test functions; not test codeunits. It specifies that a test function uses the TestPermissions property setting of the test codeunit to which it belongs. If you use this value on a test codunit, the property will resolve to Restrictive at runtime.
Apart from InheritFromTestCodunit, the values themselves do not perform any operations or have any specific behavior. Instead, you programmatically define what each value does, and the permissions sets it applies at runtime, by adding code in a test runner codeunit.
The TestPermissions property works together with the OnBeforeTestRun and OnAfterTestRun triggers in test runner codeunits. The value of of the TestPermissions property is passed as a parameter to the test runner codeunit triggers. The permission sets that are used during a test are determined by the code that you add to the triggers. Typically, you use the OnBeforeTestRun trigger to apply permissions sets and the OnAfterTestRun trigger to clear permissions sets.
