Currently I am trying to use "TTestDataProvider" to provide my test cases with test data. However, in the following example, I have encountered a memory release problem that I cannot solve myself. The destructor of the "TObjectProvider" class seems to be called before the actual test run: unit UTest; interface uses DUnitX.TestFramework, DUnitX.InternalDataProvider, DUnitX.Types, Generics.Collections; type TTestObj = class Name: string; end; TObjectProvider = class(TTestDataProvider) private type TTestData = record Name: string; Data: TTestObj; end; var FList: TList<TTestData>; public constructor Create; override; destructor Destroy; override; function GetCaseCount(const AMethodName: string): Integer; override; function GetCaseName(const AMethodName: string; const ACaseNumber: Integer): string; override; function GetCaseParams(const AMethodName: string; const ACaseNumber: Integer): TValueArray; override; end; type [TestFixture] TMyTestObject = class public [TestCaseProvider('TObjectProvider')] procedure TestObject(const AValue: TTestObj); end; implementation uses SysUtils, Math, DUnitX.TestDataProvider; { =========================================================================== } constructor TObjectProvider.Create; var Item: TTestData; begin inherited; FList := TList<TTestData>.Create; Item.Name := 'Testobject 1'; Item.Data := TTestObj.Create; Item.Data.Name := 'Testobject.Name 1'; FList.Add(Item); Item.Name := 'Testobject 2'; Item.Data := TTestObj.Create; Item.Data.Name := 'Testobject.Name 2'; FList.Add(Item); end; { =========================================================================== } destructor TObjectProvider.Destroy; var item: TTestData; begin for item in FList do //<-- Remove me to succeed but leak the objects FreeAndNil(item.Data); //<-- Remove me too. FreeAndNil(FList); inherited; end; { =========================================================================== } function TObjectProvider.GetCaseCount(const AMethodName: string): Integer; begin Result := FList.Count; end; { =========================================================================== } function TObjectProvider.GetCaseName(const AMethodName: string; const ACaseNumber: Integer): string; begin Result := Self.ClassName + '[' + FList[ACaseNumber].Name + ']'; end; { =========================================================================== } function TObjectProvider.GetCaseParams(const AMethodName: string; const ACaseNumber: Integer): TValueArray; begin SetLength(Result, 1); Result[0] := FList[ACaseNumber].Data; end; { =========================================================================== } { TMyTestObject } procedure TMyTestObject.TestObject(const AValue: TTestObj); begin Assert.IsNotNull(AValue); Assert.IsNotEmpty(AValue.Name); end; { =========================================================================== } initialization TestDataProviderManager.RegisterProvider('TObjectProvider', TObjectProvider); end. Can anyone give me a tip on how to solve this problem?
