With the helper function, we touch on the core of this test example – making use of a test page to achieve #0007, that is, testing that the user can assign a default customer category to a specific customer. The following is what the helper function looks like:

local procedure
    SelectAssignDefaultCategoryActionOnCustomerCard(
        CustomerNo: Code[20])
var
    CustomerCard: TestPage "Customer Card";
begin
    CustomerCard.OpenView();
    CustomerCard.GoToKey(CustomerNo);
    CustomerCard."Assign default category".Invoke();
end;

Note that I did not use a with-do construct to unambiguously show that the three statements in the function are referencing methods that you will only find on test page objects, and not on normal pages:

• OpenView: Opens the test page in view mode
• GoToKey: Finds the row in a dataset that is identified by the specified values
• Invoke: Invokes an action on a test page
