Mouse hovers in CodedUI

Manually recording mouse hovers

Under some circumstances, a particular control that’s being used in a coded UI test might require you to use the keyboard to manually record mouse hover events. For example, when you test a Windows Form or a Windows Presentation Foundation (WPF) application, there might be custom code. Or, there might be special behavior defined for hovering over a control, such as a tree node expanding when a user hovers over it. To test circumstances like these, you have to manually notify the Coded UI Test Builder that you are hovering over the control by pressing predefined keyboard keys.

When you perform your coded UI test, hover over the control. Then press and hold Ctrl, while you press and hold the Shift and R keys on your keyboard. Release the keys. A mouse hover event is recorded by the Coded UT Test Builder.

After you generate the test method, code similar to the following example will be added to the UIMap.Desinger.cs file:

// Mouse hover '1' label at (87, 9)
Mouse.Hover(uIItem1Text, new Point(87, 9));

Configuring mouse hover keyboard assignments
If necessary, the default keyboard assignment of Ctrl+Shift+R that is used to apply mouse hovering events in your coded UI tests can be configured to use different keys.
To change the keyboard assignments, you must modify the following configuration file:
<drive letter:>\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CodedUITestBuilder.exe.config
In the configuration file, change the values for the HoverKeyModifier and HoverKey keys to modify the keyboard assignments:
<!-- Begin : Background Recorder Settings -->
<!-- HoverKey to use. -->
<add key="HoverKeyModifier" value="Control, Shift"/>
<add key="HoverKey" value="R"/>
If having issues with recording mouse hovers on a website, then here Is the fix
Setting implicit mouse hovers for the web browser
In many websites, when you hover over a particular control, it expands to show additional details. Generally, these look like menus in desktop applications. Because this is a common pattern, coded UI tests enable implicit hovers for Web browsing. For example, if you record hovers in Internet Explorer, an event is fired. These events can lead to redundant hovers getting recorded. Because of this, implicit hovers are recorded with ContinueOnError set to true in the UI test configuration file. This allows playback to continue if a hover event fails.
To enable the recording of implicit hovers in a Web browser, open the configuration file:
<drive letter:>\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CodedUITestBuilder.exe.config
Verify that the configuration file has the key RecordImplicitiHovers set to a to a value of true as shown in the following sample:
<!--Use this to enable/disable recording of implicit hovers.-->
<add key="RecordImplicitHover" value="true"/>
