Microsoft Certified: Dynamics 365 Business Central Developer Associate MB-820 Question # 38 Topic 4 Discussion

To roll back changes to a test method after run time, you should:

Set the TransactionModel attribute to AutoRollback.

To run an approve action on a test page named TestPageA, you should:

Configure TestPageA.Approve.Invoke().

In Business Central's testing framework, the TransactionModel attribute can be set to AutoRollback. This ensures that any changes made during the test are rolled back after the test is complete, leaving the database in its original state.

For running an action on a test page, you would use the 'Invoke' method on the action you wish to perform. In this case, to run an approve action on TestPageA, you would use TestPageA.Approve.Invoke() within your test codeunit. This simulates the user action of approving something on the page.

These actions ensure that the testing environment is properly set up to test specific functionalities without persisting test data and to invoke actions as part of the test scenarios.
