Testing With Permission Sets

Articolo
09/20/2016

You can write application tests in C/AL that use specific permission sets when the test is run. The permission sets define the access rights (such as read, write, and execute ) on tables, reports, functions, and other objects in the database.

Without applying any permission sets, a test will run with full permissions, similar to the rights that are granted by the SUPER permission set. This is probably satisfactory for testing the functionality in general. However, in most cases, users will be running with a permission set that limits their access to the functionality they need to do their work.

Important

Security filters are not tested.

Overview

To run tests with permission sets requires that you work with test codeunits and/or test functions and test runner codeunits.

Test codeunits and test functions

Test codeunits and test functions include the TestPermissions property. This property has the following values: Disabled, Restrictive, NonRestrictive, InheritFromCodeunit. The values alone do not assign any permission sets to the test. At runtime, the property value is passed on to the OnBeforeTestRun and OnAfterTestRun triggers of test runner codeunits.You define which permission sets are applied to the test for each value by coding the OnBeforeTestRun and OnAfterTestRun triggers of a test runner codeunit. For more information, see TestPermissions Property
Test runner codeunits

You use test runner codeunits to apply the permission sets to use in the test based on the value of the TestPermissions property of the test. You do this by adding code to the OnBeforeTestRun and OnAfterTestRun triggers of the test runner codeunit. These triggers include the TestPermissions data type parameter. The TestPermissions data type parameter takes the value of the TestPermissions property that is passed on from the test codeunit or test function that is run. On the triggers, you add code to define what permission sets to use for the test according to the value of the TestPermissions data type parameter.

Typically, you code the OnBeforeTestRun trigger to assign the permission sets to the test, and the OnAfterTestRun trigger to clear the permission sets.

To summarize, a test codeunit or test function defines a general permission set level to use in a test run, while the test runner codeunit determines the specific permission set to use in the test run.

General Procedure for Using Permission Sets in Tests

Determine the application functionality that you want to test with permission sets.
Add or modify test codeunits or test functions that perform the tests.

Set the TestPermissions property to the desired permission set level.
Add or modify test runner codeunits that run the test codeunits and test functions.

Add logic to the OnBeforeTestRun and OnAfterTestRun triggers to apply and clear the permission sets for the test.

Example

This simple code example illustrates how to test with permission sets. It uses a test runner codeunit to apply permission sets to test functions. The applied permission sets are determined by the different values of the TestPermissions property of the test function.

For applying permission sets, the code uses a DotNet data type variable for Microsoft.Dynamics.Nav.PermissionTestHelper assembly. This assembly is provided as a server add-in with the Microsoft Dynamics NAV Server installation.

The OnBeforeTestRun trigger will apply one of three permission sets, which have the Role IDs O365 BASIC, O365 BUS FULL ACCESS, and SUPER.
