Bug 156133 – DumpRenderTree, WebKitTestRunner should be more strict about waitUntilDone()/notifyDone()

• Status: NEW
• Component: Tools / Tests

[David Kilzer (:ddkilzer)]

The fix for Bug 149319 (r198963) included a broken test that only called notifyDone(), but never called waitUntilDone():

Bug 149319: Backdrop Filter should repaint when changed via script
<https://bugs.webkit.org/show_bug.cgi?id=149319>
<http://trac.webkit.org/changeset/198963>

It was fixed in r198971:  <http://trac.webkit.org/changeset/198971>

However, this got me to thinking about whether we could detect such a bad test before it lands by being stricter (meaning crash DumpRenderTree or WebKitTestRunner with an RELEASE_ASSERT) about two conditions:

1. Calling notifyDone() before calling waitUntilDone().
2. Calling waitUntilDone() after calling notifyDone().

If there are any DumpRenderTree or WebKitTestRunner crashes with this patch, that means a layout test exists that calls waitUntilDone()/notifyDone() in the wrong order.

Okay, this proof-of-concept indicates there might be some work to do here, but I don't have time to spend on it immediately.
