crm|SAP CL_CRM_BOL_ENTITY单元测试方法 saprfc|erp|abap|sap

In SAP standard development it is very important to use unit test to cover those changes on legacy code to try to avoid side effect. As type reference CL_CRM_BOL_ENTITY is widely used in UI component code, I would like to find a way to construct its reference by sample data.
The normal way we get instance of CL_CRM_BOL_ENTITY is, to use query or dquery method provided in class CL_CRM_BOL_CORE, which return a BOL collection list and then we can get each bol entity from by iterating that collection. However, both of these methods will perform database scan and return found data – such behavior is not appropriate for unit test.
I have gone through all public methods in CL_CRM_BOL_CORE and do not find a useful method to construct bol entity based on sample data, so I write a small piece of code:

I create a class which inherits CL_CRM_BOL_ENTITY:

Create a static private attribute:

And initialize it in class_constructor:

METHOD class_constructor. so_bol_core = cl_crm_bol_core=>get_instance( ). so_bol_core->load_component_set( 'PROD_ALL' ). ENDMETHOD.

The signature and source code are listed below:

CREATE DATA lr_entity. lr_entity->instance = lr_cast->data_ref->instance. ro_result = NEW cl_crm_bol_entity( iv_cont_proxy = lr_cast iv_manager_entry = lr_entity ). ENDMETHOD. And below is an example how to construct BOL entity using this utility method: CONSTANTS: cv_prod_guid TYPE crmt_object_guid VALUE '0123456789123456'. DATA(ls_prod_header) = VALUE comt_product_ui( product_guid = cv_prod_guid product_id = 'I042416' product_type = '01' ).DATA(ro_entity) = zcl_prod_unit_test_tool=>get_fake_bol_entity( iv_bol_name = 'Product' is_data = https://www.it610.com/article/ls_prod_header iv_key = cv_prod_guid ).DATA(lv_type) = ro_entity->get_property_as_string( 'PRODUCT_TYPE' ). DATA(lv_guid) = ro_entity->get_property_as_string( 'PRODUCT_GUID' ). DATA(lv_id) = ro_entity->get_property_as_string( 'PRODUCT_ID' ).WRITE: / lv_type. WRITE: / lv_guid. WRITE: / lv_id.
