Performing Value Checks for Web Dynpro ABAP Applications

Use

In this step you can test the status of the application following a round trip, and check that the application produces the expected results.

Class CL_WD_WEB_DYNPRO_TESTER provides you with the following methods to perform these tests:

Method

Description

GET_CONTEXT_MENU

Getter method for the displayed context menu (entries that were defined by the application)

GET_CONTEXT_ROOT_NODE

Getter method for the root element of the context

GET_MESSAGES

Getter method for Web Dynpro messages

GET_UI_ELEMENT

Getter method for Web Dynpro UI element (CL_WD_...)

GET_UI_ELEMENT_PROPERTY

Getter method for the values of UI element properties visibility, enabled, readOnly, and required. Also checks whether values have been changed with personalization.

Example

You want to perform a unit test of Web Dynpro application CONFIGURE_COMPONENT (editor for Web Dynpro ABAP component configuration).

In the first step you already defined which steps are to be followed when the application is run in the background: The user starts the application, selects a Checkbox, enters an invalid value in an InputField, and then closes the application. For more information, see Running Web Dynpro ABAP Applications Without a Browser.

In the following procedure you can now check whether the individual software units produce the expected results:

  1. After the user has selected the CheckBoxAdvanced Settings, the InputFieldConfiguration Type should appear.

    To check this, you can use the following source code:

                
lo_uielement = tester->get_ui_element( component_path = 'SELECTION_SCREEN'
            
view_id = 'ENTRY_MAIN'
            
uielement_id = 'EXTENDED_CONF_TYPE_DD').
            
tester->get_ui_element_property( EXPORTING ui_element = lo_uielement
            
IMPORTING visible = lv_vis ).
            
cl_abap_unit_assert=>assert_equals(
            
exp = cl_wd_uielement=>e_visible-visible
            
act = lv_vis ).

  2. After the user has entered an invalid value in the Configuration VariantInputField, an error message should appear.

    To check this, you can use the following source code:

                
lt_messages = tester->get_messages( ).
            
cl_abap_unit_assert=>assert_equals(
            
exp = '1'
            
act = lines( lt_messages ) ).
