Missing generic Assert

[pjljvandelaar]

Dear AUnit developers,

AUnit provides

aunit/include/aunit/framework/aunit-assertions.adb

Line 99 in 552a240

procedure Assert

to compare the expected and actual values of Strings.

I am missing similar Asserts for other types than String.
This can be solved by a generic specified as

   generic
      type Element_T is (<>);
   procedure Generic_Assert
     (Actual    : Element_T;
      Expected  : Element_T;
      Message   : String;
      Source    : String  := GNAT.Source_Info.File;
      Line      : Natural := GNAT.Source_Info.Line);
   --  Specialized versions of Assert, they call the general version that
   --  takes a Condition as a parameter

and implemented as

   procedure Generic_Assert
     (Actual   : Element_T;
      Expected : Element_T;
      Message  : String;
      Source   : String  := GNAT.Source_Info.File;
      Line     : Natural := GNAT.Source_Info.Line)
   is
   begin
     Assert
        (Condition => Expected = Actual,
         Message   => Message & ASCII.CR & ASCII.LF &
           "Expected : " & Element_T'Image (Expected) & ASCII.CR & ASCII.LF &
           "Actual   : " & Element_T'Image (Actual),
         Source    => Source,
         Line      => Line
        );
   end Assert;

and use it as follows

   procedure Assert is new AUnit.Assertions.Generic_Assert (Count_Type);
   ....
      Assert (Expected => Lead.Length,
              Actual   => Actual_Lead.Length,
              Message  => "Different sizes of Lead");
   ...

With Ada2020, the generic can even be made more general, since Image is defined on more types.

Could you consider adding this functionality to AUnit?
Since it will make my test cases shorter, clearer and easier to read.
