creation of test class method by using detourContext in d 365

Hi all my invent table has following update method has following code :

       super()

        if (this.PhysicalDimensionInventoryUnitOfMeasure(this_Orig))
        {
            this.DimensionInventoryUnitOfMeasure();
        }

now we can create 2 test class method in inventtabletest using de detour   build the project and run the test method both will get passed.

:



    // <summary>
    /// Tests shouldUpdatePhysicalDimensionInventoryUnitOfMeasure method returns false if inventory net weight is not updated.
    /// </summary>
    [SysTestMethod]
    public void update_ShouldUpdatePhysicalDimensionInventoryTrue_PhyscialDimUpdated()
    {
        ttsbegin;
        using (var detourContext = SysDetourContext::createContext())
        {
            // Arrange
            detourContext.whenMethodCalled(
                UtilElementType::Table,
                tableStr(InventTable),
                tableMethodStr(InventTable, shouldUpdatePhysicalDimensionInventoryUnitOfMeasure))
            .doReturnValue(true);
            WHSPhysDimUOM   WHSPhysDimUOM;
            WHSPhysDimUOM.Width     = 0;
            WHSPhysDimUOM.UOM       = InventTableModule::find(inventTable.ItemId, ModuleInventPurchSales::Invent).UnitId;
            WHSPhysDimUOM.ItemId    = inventTable.ItemId;
            WHSPhysDimUOM.Depth     = 0;
            WHSPhysDimUOM.Height    = 0;
            WHSPhysDimUOM.doInsert();
            inventTable.selectForUpdate(true);
            inventTable.grossDepth  = 10;
            inventTable.grossHeight = 20;
            inventTable.grossWidth  = 30;
            inventTable.TaraWeight  = 10;
            inventTable.NetWeight   = 20;
            //inventTable.update();
            // Act
            inventtable.update();
            WHSPhysDimUOM.reread();
            // Assert
            this.assertEquals(inventTable.grossDepth, WHSPhysDimUOM.Depth, 'The depth value of physical dimension table should match with grossDepth of inventory table.');
            this.assertEquals(inventTable.grossHeight, WHSPhysDimUOM.Height, 'The height value of physical dimension table should match with grossHeight of inventory table.');
            this.assertEquals(inventTable.grossWidth, WHSPhysDimUOM.Width, 'The width value of physical dimension table should match with grossWidth of inventory table.');
            this.assertEquals(inventTable.grossWeight(), WHSPhysDimUOM.Weight, 'The weight value of physical dimension table should match with grossWeight of inventory table.');
