Testing Pages

You use test page objects to simulate user interactions with the application. You can:

View or change the value of a field on a test page.
View the data on page parts.
View or change the value of a field on a subpage.
Filter the data on a test page.
Perform any actions that are available on the page.
Navigate to different records.

You must consider how you set the TransactionModel Property to simulate the scenario that you want to test and to return the database to its initial state after the test.

Note

Test functions and code on test pages run on the Microsoft Dynamics NAV Server instance, even though they simulate client interactions.

Accessing Fields on Test Pages

You access the fields on a test page by using the dot notation. For example, if you have a test page variable named CustomerCard that represents the Customer Card page, then to access the Name field on the test page, you write CustomerCard.Name in your code.

To get the value of a field or to write a value in a field, you use the Value property. For example, if you have a test page variable named CustomerCard that represents the Customer Card page, then to assign the value of the No. field to a variable named CustNo, you write CustNo := CustomerCard."No.".Value in your code. To write a value in the Address field of a Customer Card page, you write CustomerCard.Address.Value := '<address>' in your code.

For more information about C/AL functions that you use to access fields on a test page, see TestPage Field Functions.

Accessing Page Parts and Subpages

You access page parts and subpages on a test page by using the dot notation. For example, to compare the value of the No. field on a page to the value of the No. field on a FactBox on the page, you can write the following code.

If CustomerCard."No.".Value <> CustomerCard."Sales Hist. Sell-to FactBox"."No.".Value THEN  
  ERROR("Page part data is not updated.");

You can use the Symbol Menu to view page parts and subpages and to access the functions, properties, fields, and actions on page parts and subpages.

Filtering Data on Test Pages

To filter the data that can be accessed on a test page, you use the Filter property and filter functions. For example, to filter the customers on the Customer List page based on a range of values in the No. field, you can write the following code.

CustomerList.Filter.SETFILTER("No.", '20000..30000');

For more information about C/AL functions that you use for filtering, see TestPage Filter Functions.

Invoking Actions on Test Pages

Any action that is available on a page is also available on the test page that mimics that page. You access page actions by using the dot notation and the INVOKE Function (TestPage Action). You can use the Symbol Menu to view the actions that are available on a test page. To view actions that you designed by using Page Designer, select the test page variable in the first column of the symbols, and then select Actions in the second column. To view built-in actions, such as Yes, No, OK, or Cancel, select the test page variable in the first column of the symbols, and then select BuiltInActions in the second column.

Note

The Symbol Menu may include built-in actions that are not available on the page. If you call a built-in action that is not available on the page, then the test fails.

For example, to choose OK after you create a new customer on the Customer Card page, you can write the following code.

CustomerCard.OPENNEW;  
CustomerCard.Name.Value := 'Adventure Works';  
CustomerCard.OK.INVOKE;

Navigating Among Records

To simulate moving to different items on a list page or moving to different records on a card page, you use one of the following navigation functions:
