Here is how one can add FULL Coded UI Test support for a 3rd party control based on Windows Forms technology.<\/p>\n

Implementation Method \u2013 Accessibility<\/strong><\/span><\/p>\n

Accessibility means having equal access to web-based information and services regardless of physical or developmental abilities or impairments. Once implemented, it helps developers make their programs more compatible with accessibility aids (help users with impairment to use programs more effectively).<\/p>\n

Microsoft has developed two accessibility standards – Microsoft Active Accessibility (MSAA) and Microsoft UI Automation (UIA)<\/p>\n

MSAA is designed to help Assistive Technology (AT) products interact with standard and custom user interface (UI) elements of an application (or the operating system), as well as to access, identify, and manipulate an application’s UI elements including enabling automation testing.<\/p>\n

UIA is a newer technology that provides a much richer object model than MSAA, and is compatible with both Win32 and the .NET Framework. It is designed so that it can be supported across platforms other than Microsoft Windows.<\/p>\n

We recommend MSAA for Windows Forms because Windows Forms natively supports MSAA and not UIA. Although there is MSAA to UIA & vice-versa conversion available via built-in proxybridge but the results in an extra layer of dependency which could eat into performance, hence MSAA.<\/p>\n

Why Accessibility for Coded UI Test?<\/span><\/strong><\/p>\n

1. Implementing accessibility is simpler because one needs to follow established guidelines that serve the purpose of developing testable as well as accessible controls in one go<\/p>\n

2. There is not much need to write an entire plugin for controls as much of the work is already done. We have built plugins for Windows Forms and Windows Presentation Foundation controls using accessibility technologies and have exposed appropriate extension points for easy hook-up<\/p>\n

3. Vendors such as Telerik who develop 3rd party controls have already announced accessibility implementation<\/a><\/p>\n

\u00a0<\/p>\n

Detailed steps with reference to <\/span>Coded UI Test Extension for 3rd party controls – the basics explained<\/span><\/a><\/span><\/strong><\/p>\n

Level 1 \u2013 Basic Record and Playback<\/span><\/strong><\/p>\n

How can I make a third party GridView with rows and cells to work with basic recording and playback of Coded UI Test?<\/strong><\/p>\n

1. Implement MSAA on existing control<\/p>\n

\"image\"<\/p>\n

2. Override Accessibility methods while you refer to http:\/\/msdn.microsoft.com\/en-us\/library\/system.windows.forms.accessibleobject_methods.aspx<\/a><\/p>\n

\"image\"<\/p>\n

3. Example GetChild<\/em> implementation<\/p>\n\n\n\n
\n

\n public override AccessibleObject GetChild(int index) <\/span>
{ <\/span>
\u00a0\u00a0\u00a0 if (index >= 0 && index < this.GetChildCount()) <\/span>
\u00a0\u00a0\u00a0 { <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 GridViewCellInfo cellInFocus = row.Cells[index]; <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 RectangleF rectangle = GetCellElement(row, owner.Columns[index]); <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return new CellAccessibleObject(owner, cellInFocus, <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 owner.TableElement.ViewElement.RowLayout.RenderColumns[index+1], <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 this, new Point((int)rectangle.X, (int)rectangle.Y), <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 new Size((int)rectangle.Width, (int)rectangle.Height), <\/span>
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 row.Cells[index].Value); <\/span>
\u00a0\u00a0\u00a0 } <\/span>
\u00a0\u00a0\u00a0 return null; <\/span>
}<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Level 2 \u2013 Rich Property Validation<\/span><\/strong><\/p>\n

How to add BackColor \/ ForeColor \/ BorderColor properties of the Cell so I can assert on the values using the Coded UI Test Builder?<\/strong><\/p>\n

1. Override Description<\/em> method of AccessibleObject<\/em> and pass rich property values as semi-colon separated string. This modification needs to be added in the custom control code.<\/p>\n\n\n\n
\n

\n public override string Description
{
\u00a0\u00a0\u00a0 get
\u00a0\u00a0\u00a0 {
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return “GridViewCellInfo ;” + cell.Value+”;”+this.cell.Style.BackColor.A + “, ” +
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 this.cell.Style.BackColor.B + “, ” + cell.Style.BackColor.G + “;” + this.cell.Style.ForeColor.A + “, ” +
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 this.cell.Style.ForeColor.B + “, ” + cell.Style.ForeColor.G + “;” + this.cell.Style.BorderColor.A + “, ” +
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 this.cell.Style.BorderColor.B + “, ” + cell.Style.BorderColor.G+”;”+cell.IsSelected;
\u00a0\u00a0\u00a0 }
}<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\u00a0<\/p>\n

2. A plugin needs to be written on top of PropertyProvider. Write custom PropertyProvider<\/em> and implement GetPropertyValue<\/em> method. Use this method to retrieve the semi-colon separated property values<\/p>\n\n\n\n
\n

\n public override object GetPropertyValue(UITestControl uiTestControl, string propertyName)
{
\u00a0\u00a0\u00a0 if (CellPropertiesMap.ContainsKey(propertyName) &&

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 IAccessible a = native[0] as IAccessible;<\/span>\n <\/p>\n

\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 if (string.Equals(propertyName, GridViewCellInfo.PropertyNames.BackColor, StringComparison.OrdinalIgnoreCase))
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 {

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return descriptionTokens[3];

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 }
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 throw new NotSupportedException();
\u00a0\u00a0\u00a0 }

\u00a0\u00a0\u00a0 }
\u00a0\u00a0\u00a0 finally
\u00a0\u00a0\u00a0 {

\u00a0\u00a0\u00a0 }
}<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

3. Define a Dictionary of custom property names and UITestPropertyDescriptor<\/em> property types<\/p>\n\n\n\n
\n

\n private static Dictionary CellPropertiesMap
{
\u00a0\u00a0\u00a0 get

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 if (cellPropertiesMap == null)
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 {

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 cellPropertiesMap.Add(“ForeColor”, new UITestPropertyDescriptor(typeof(string), read));

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 }<\/span>\n <\/p>\n

\n \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return cellPropertiesMap;
\u00a0\u00a0\u00a0 }
}<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

4. Override *GetPropertyDescriptor *and return the property types set in step 3<\/p>\n\n\n\n
\n

\n public override UITestPropertyDescriptor GetPropertyDescriptor(UITestControl uiTestControl, string propertyName)

5. Override GetpropertyNames *of *PropertyProvider<\/em><\/p>\n\n\n\n
\n

\n public override ICollection GetPropertyNames(UITestControl uiTestControl)

6. Override GetControlSupportLevel<\/em> of *PropertyProvider. *The method should be set to return maximum Control Support for the custom control which in this case includes Table, Row and Cell<\/p>\n\n\n\n
\n

\n public override int GetControlSupportLevel(UITestControl uiTestControl)

\n }<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

This completes the PropertyProvider implementation to add rich control validation. Now we need to add this service to the UITestExtension package.<\/p>\n

7. Implement GetService<\/em> of UITestExtensionPackage<\/em><\/p>\n\n\n\n

What do I need to do in order to see objects of custom classes in the auto-generated code after recording user actions?<\/strong><\/p>\n

1. Add specialized class for control extending from WinControl, in this example, Cell control (GridViewCellInfo)<\/em><\/p>\n

2. Add Custom Property Names in the Specialized class if desired<\/p>\n\n\n\n

This completes the PropertyProvider implementation to add custom code generation. Since we have already added the property provider service in Level 2, we need to re-deploy the binaries to “%CommonProgramFiles(x86)%Microsoft SharedVSTT10.0UITestExtensionPackages” directory<\/p>\n

Level 4 \u2013 Intent Aware Actions<\/span><\/strong><\/p>\n

How can I aggregate a double click on a cell followed by edit text into one action – set value on cell?<\/strong><\/p>\n

Write aggregators for recording setValue and property provider for playing back the setValue.<\/p>\n

1. Write custom ActionFilter<\/em> and implement ProcessRule<\/em> to filter actions<\/p>\n\n\n\n
\n

\n public override bool ProcessRule(IUITestActionStack actionStack)
{
\u00a0\u00a0\u00a0 if (actionStack.Count < 2)
\u00a0\u00a0\u00a0 {
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return false;
\u00a0\u00a0\u00a0 }
\u00a0\u00a0\u00a0 SetValueAction lastAction = actionStack.Peek() as SetValueAction;
\u00a0\u00a0\u00a0 MouseAction mouseAction = actionStack.Peek(1) as MouseAction;
\u00a0\u00a0\u00a0 if (lastAction != null && mouseAction != null)
\u00a0\u00a0\u00a0 {
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 if (lastAction.UIElement != null &&
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 lastAction.UIElement.ControlTypeName.Equals(ControlType.Edit.ToString(), StringComparison.OrdinalIgnoreCase) &&
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 mouseAction.UIElement != null &&
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 mouseAction.UIElement.ControlTypeName.Equals(ControlType.Cell.ToString(), StringComparison.OrdinalIgnoreCase))
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 {
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 actionStack.Pop();

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 SetValueAction newCellAction = new SetValueAction(cellAction.UIElement, lastAction.Value);
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 newCellAction.AdditionalInfo = “Aggregated”;
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 actionStack.Push(newCellAction);
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 }
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return false;
\u00a0\u00a0\u00a0 }<\/span>\n <\/p>\n

\n }<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\u00a0<\/p>\n

2. Override GetPropertyForAction\u00a0 of PropertyProvider<\/em> if you want to define custom action names<\/p>\n\n\n\n
\n

\n public override string GetPropertyForAction(UITestControl uiTestControl, UITestAction action)
{
\u00a0\u00a0\u00a0 if (uiTestControl.ControlType.Equals(ControlType.Cell))
\u00a0\u00a0\u00a0 {
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 return GridViewCellInfo.PropertyNames.CellValue;
\u00a0\u00a0\u00a0 }
\u00a0\u00a0\u00a0 throw new NotSupportedException();
}<\/span>\n <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

This completes the PropertyProvider implementation to add rich control validation. Now we need to add this service to the UITestExtension package.<\/p>\n

3. Implement SetPropertyValue *of *PropertyProvider<\/em><\/p>\n\n\n\n
\n

\n public override void SetPropertyValue(UITestControl uiTestControl, string propertyName, object propertyValue)
{
\u00a0\u00a0\u00a0 isInThisProvider = true;
\u00a0\u00a0\u00a0 try

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 }
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 else if (string.Equals(propertyName, GridViewCellInfo.PropertyNames.CellValue, StringComparison.OrdinalIgnoreCase))
