CodedUI Test: Keyboard.SendKeys not working

问题

I'm trying to use the CodedUI Test feature of Visual Studio 2010. I've got a problem while replaying the various actions for one of my html component. The Keyboard.SendKeys generated do not work (like if there was no input).

The code generated is :

// Type '{F4}{F4}{F2}titre{Enter}' in 'SaisieSD_DS' custom control
Keyboard.SendKeys(uISaisieSD_DSCustom, this.Params.UISaisieSD_DSCustomSendKeys, ModifierKeys.None);

If I replace the call to Keyboard.SendKeys by a call to System.Windows.Forms.SendKeys.SendWait, it does work.

I was thinking about a problem due to a loss of focus. However, if i do something like uISaisieSD_DSCustom.SetFocus(), it doesn't change the behavior.

Do you have any idea ?

thx.

回答1:

Have you tried

uISaisieSD_DSCustom.WaitForReady()

Or one of the other waitfors?

Is it failing on this line? Or is it failing afterward due to this not working correctly?

You can also use the following to wait for all threads to complete before proceeding:

Playback.PlaybackSettings.WaitForReadyLevel = WaitForReadyLevel.AllThreads;
Keyboard.SendKeys(uISaisieSD_DSCustom, this.Params.UISaisieSD_DSCustomSendKeys, ModifierKeys.None);
Playback.PlaybackSettings.WaitForReadyLevel = WaitForReadyLevel.UIThreadOnly;

Just make sure you include the last line to turn it back to UIThreadOnly, or it will slow everything way down.

Visual Studio CodedUI Test searches for a control and sends those keys to it. In your case the control is 'uISaisieSD_DSCustom'. You can try using:

Keyboard.SendKeys(this.Params.UISaisieSD_DSCustomSendKeys);

OR

Keyboard.SendKeys("{F4}{F4}{F2}titre{Enter}");

After typing the URL if we want to send the enter key then the below code works in Coded UI

Keyboard.SendKeys("{Enter}");
