robot: improve mouse interaction with iframes

[haysmark]

See: ​http://archive.dojotoolkit.org/nightly/checkout/dijit/tests/editor/robot/Editor_mouse.html

The test double clicks in the center of the Editor to select the text and delete all of it. The problem is that is the full extent of the robot's ability to interact with the Editor; if you tell the robot to point the mouse at text inside the Editor (the text is in an iframe) it will fail to move the mouse over the text.

We could write more robust tests for Editor if the robot could click through iframes.

Fixes #10015. Added new robot logic for clicking nodes inside nested iframes. Added new Editor tests.

(In [20453]) Fixes #10015 !strict. Proxy commit for haysmark (CCLA on file). Add multi-iframe scrollIntoView into robot API for dijit. Add editor test that makes use of the new API.

Guys, this new Editor_iframe.html robot test is failing for me on IE6, IE8, and FF3.5/win. (It does work on chrome for me.) The test also has hundreds of lines of copied code from Editor_mouse.html, which is a maintenance problem. But most importantly, this test doesn't seem to be a test of Editor at all, it's a test of DOH's scrollIntoView().

If you want to test the new DOH functionality please add the test to the doh/ directory instead.

If you want to test editor/mouse interaction, for example using the mouse to position the caret at a certain position, or to select certain text in the editor, feel free to add those tests to the existing Editor_mouse.html.

Thanks.

(In [20663]) Please add tests of robot into unit tests for robot itself, rather than into tests for editor. Refs #10015.

(In [22987]) On Chrome 6 on Windows, the delete key is no longer deleting the space before the highlighted word. At least for me. Refs #10015.

[Douglas Hays]

(In [23004]) Refs #10015. Delete unused test file.

(sadly) punting seemingly abandoned ticket and meta tickets to future

I guess this is actually fixed, except for the test case. I'll just close it.
