Other Items:

type Test_Count_Type is new Natural;
Type for the test count. This effectively limits the amount tests to whatever Natural is.

Although, in practice when adding tests the limit is not checked.


type Test is abstract new Ada.Finalization.Controlled with null record;
A type, which provides the base for Test_Case and Test_Suite types.

type Test_Class_Access is access all Test'Class;

procedure Set_Up (T : in out Test);
Set_Up is called before executing the test procedure.

By default, the procedure does nothing, but derived types can overwrite this method and add their own customisations.

One should not call this explicitly by herself. The framework calls it when necessary.


procedure Tear_Down (T : in out Test);
Tear_Down is called after the test procedure is executed.

By default, the procedure does nothing, but derived types can overwrite this method and add their own customisations.

One should not call this explicitly by herself. The framework calls it when necessary.


function Get_Name (T : Test) return String is abstract;
Return the name of the test.

Types derived from the Test type are required to overwrite this procedure.


procedure Run (T         : in out Test;
               Listener  : in out Listeners.Result_Listener'Class)
  is abstract;
Run the test and place the test result to Result.

Types derived from the Test type are required to overwrite this procedure.


procedure Run (T         : in out Test;
               Test_Name :        String;
               Listener  : in out Listeners.Result_Listener'Class)
  is abstract;
Run the test with given name and place the test result to Result. Notice: If multiple tests have same name this might call all of them.

Types derived from the Test type are required to overwrite this procedure.


function Test_Count (T : Test) return Test_Count_Type is abstract;
Return the amount of tests (test routines) which will be executed when the Run (T) procedure is called.

function Test_Count (T : Test; Test_Name : String)
  return Test_Count_Type is abstract;
Return the amount of tests (test routines) which will be executed when the Run (T, Test_Name) procedure is called.

procedure Execute (T        : in out Test'Class;
                   Listener : in out Listeners.Result_Listener'Class);
Call Test class' Run method and place the test outcome to Result. The procedure calls Start_Test of every listener before calling the Run procedure and End_Test after calling the Run procedure.

This procedure is meant to be called from Runner package(s). There should be no need for other to use this.


procedure Execute (T         : in out Test'Class;
                   Test_Name :        String;
                   Listener  : in out Listeners.Result_Listener'Class);
Same as Execute above, but call the Run procedure which takes Test_Name parameter.

type Test_Case is abstract new Test with private;
The base type for other test cases.

function Get_Name (T : Test_Case) return String;
Return the name of the test case.

procedure Run (T        : in out Test_Case;
               Listener : in out Listeners.Result_Listener'Class);
Run Test_Case's test routines.

procedure Run (T         : in out Test_Case;
               Test_Name :        String;
               Listener  : in out Listeners.Result_Listener'Class);
Run Test_Case's test routine which matches to the Name.

function Test_Count (T : Test_Case) return Test_Count_Type;
Implementation of Test_Count (T : Test).

function Test_Count (T : Test_Case; Test_Name : String)
  return Test_Count_Type;
Implementation of Test_Count (T : Test, Test_Name : String).

procedure Finalize (T : in out Test_Case);
Finalize procedure of the Test_Case.

procedure Set_Name (T : in out Test_Case; Name : String);
Set Test_Case's name.

type Object_Test_Routine_Access is
  access procedure (T : in out Test_Case'Class);
A pointer to a test routine which takes Test_Case'Class object as an argument.

For this kind of test routines, the framework will call Set_Up and Tear_Down routines before and after test routine execution.


type Simple_Test_Routine_Access is access procedure;
A pointer to a test routine which does not take arguments.

procedure Add_Test_Routine (T       : in out Test_Case'Class;
                            Routine :        Object_Test_Routine_Access;
                            Name    :        String);
Register a test routine to the Test_Case object.

The routine must have signature "procedure R (T : in out Test_Case'Class)".


procedure Add_Test_Routine (T       : in out Test_Case'Class;
                            Routine :        Simple_Test_Routine_Access;
                            Name    :        String);
Register a simple test routine to the Test_Case.

The routine must have signature "procedure R".


type Test_Suite is new Test with private;
A collection of Tests.

You can either fill a Test_Suite object with Test_Case objects or nest multiple Test_Suite objects. You can even mix Test_Case and Test_Suite objects, if necessary.


type Test_Suite_Access is access all Test_Suite;

function Create_Suite (Suite_Name : String)
  return Test_Suite_Access;
Create a new Test_Suite. Caller must free the returned Test_Suite using Release_Suite.

function Create_Suite (Suite_Name : String)
  return Test_Suite;
Create a new Test_Suite. The suite and its children are released automatically.

procedure Add_Test (Suite : in out Test_Suite; T : Test_Class_Access);
Add a Test to the suite. The suite frees the Test automatically when it is no longer needed.

procedure Add_Test (Suite : in out Test_Suite; T : Test_Suite_Access);
Add a Test suite to the suite. The suite frees the Test automatically when it is no longer needed.

This is a helper function, which internally calls Add_Test (Suite : in out Test_Suite; T : Test_Class_Access).


procedure Add_Static_Test
  (Suite : in out Test_Suite; T : Test'Class);
Add a Test to the suite. This procedure is meant for statically allocated Test_Case objects.

Please note, that a copy of the Test'Class object is saved to the suite. Original test object is not modified and changes made to it after adding the test are not propagated to the added object.


function Get_Name (T : Test_Suite) return String;
Return the name of Test_Suite.

procedure Run (T      : in out Test_Suite;
               Listener  : in out Listeners.Result_Listener'Class);
Run Test_Suite's Test_Cases.

procedure Run (T         : in out Test_Suite;
               Test_Name :        String;
               Listener  : in out Listeners.Result_Listener'Class);
Run test suite's child which matches to the given name.

function Test_Count (T : Test_Suite) return Test_Count_Type;
Implementation of Test_Count (T : Test).

function Test_Count (T : Test_Suite; Test_Name : String)
  return Test_Count_Type;
Implementation of Test_Count (T : Test, Test_Name : String).

procedure Adjust (T : in out Test_Suite);
Adjust procedure of Test_Suite. Handles the copying of the structure properly

procedure Finalize (T : in out Test_Suite);
Finalize procedure of Test_Suite. Frees all added Tests.

procedure Release_Suite (T : Test_Suite_Access);
Release the memory of Test_Suite. All added tests are released automatically.
