ABAP unit test coverage not work for CONSTRUCTOR

[bazak]

There is some logic in CONSTRUTOR method of my class, So I wrote some unit test for creating instance

1. The unit tests all passed successful, no dump

2. Debugging for the UT can run into break-point of CONSTRUCTOR method.

3. Other instance method UT coverage works good.

the problem is , the UT coverage of CONSTRUTOR method always 0%, anyone met this problem?

UT code like:

CLASS ltd_test DEFINITION FOR TESTING
  DURATION SHORT
  RISK LEVEL HARMLESS
  INHERITING FROM zcl_data.
  PRIVATE SECTION.

    DATA: mo_tool_double TYPE REF TO zif_data_tool.

    METHODS: setup

    METHODS: constructor_test FOR TESTING.

ENDCLASS.

CLASS ltd_test IMPLEMENTATION.

  METHOD setup.
    mo_tool_double ?= cl_abap_testdouble=>create( 'zif_data_tool' ).

  ENDMETHOD.

  METHOD constructor_test .
    cl_abap_testdouble=>configure_call( mo_tool_double )->ignore_all_parameters( )->and_expect( )->is_called_once( ).
    mo_tool_double->get_data(  ).

    DATA lo_c TYPE REF TO zcl_data.

    CREATE OBJECT lo_c 
          EXPORTING io_double = mo_tool_double.

    cl_abap_testdouble=>verify_expectations( mo_tool_double ).
  ENDMETHOD.

ENDCLASS.

Nope. Could you provide a Minimal Reproducible Example that people can run and tell your ABAP version?

REPORT.
CLASS lcl_app DEFINITION.
  PUBLIC SECTION.
    METHODS constructor.
    DATA a TYPE i.
ENDCLASS.
CLASS ltc_app DEFINITION FINAL
  FOR TESTING RISK LEVEL HARMLESS DURATION SHORT.
  PRIVATE SECTION.
    METHODS first_test FOR TESTING RAISING cx_static_check.
ENDCLASS.
CLASS lcl_app IMPLEMENTATION.
  METHOD constructor.
    IF sy-uzeit < '120000'.
      a = 1.
    ELSE.
      a = 2.
    ENDIF.
  ENDMETHOD.
ENDCLASS.
CLASS ltc_app IMPLEMENTATION.
  METHOD first_test.
    DATA(app) = NEW lcl_app( ).
  ENDMETHOD.
ENDCLASS.

Hello, thanks for reply, Its in SAP GUI SE24, seems different with ADT, ABAP version : ABAP PLATFORM 2023

I was following : Constructor Dependency Injection for ABAP Unit Testing
