Hmm. I always thought reveal() should be application-specific.

The reveal() for IE's DOM would just be spIE->Visible = true;, except
reveal() _should_ block the test case until the user dismisses the
revealer. That rule is optional so long as the visible web browser
does not resume running all its other tests in your face before you
can review the current situation. You can fix that by calling exit()
to whack the test cases after the browser reveals. _That_ breaks the
rule that after you close the revealer the current test case resumes
its activations and assertions.

Next, if you simulate a browser (like with HttpUnit), you can put
together another incomplete reveal() by writing the current page's
HTML to scratch.html, and raising this in a browser. This technique
discards DOM interactivity (the simulated JavaScript might not run),
and it requires scratch.html can see relative paths to its support
files, such as "/images/penBird.png" or
"/scripts/myFavoriteScripts.js".

Such a reveal() can position scratch.html within a known repository of
such files (the cheap fragile way), or it can download and refresh all
these files dynamically (the expensive and still fragile way).

So, an application-specific reveal() could perform just enough of its
requirements to reveal the tested GUI, and propel development. A
generic reveal() must satisfy enough of these requirements to not slow
most kinds of site development down, and must be flexible enough to
accept application-specific fixups.

So, inconclusion, I suck at productization. Jim Shore might possibly
be a little better at it, so go for it! Nobody is _required_ to use a
default reveal(). Sometimes I just Tidy and dump the HTML, and read
it...
