Attachment: (Cv1) TestRunner.js: more consistent updateUI() output (+ minor whitespace+code cleanup)

*Use same partial-green color in header as in details.
*Add a 'ToDo' header case, just in case.
*Failures don't turn Success column red anymore !
 *(That's what made me file this bug.)
*Add some missing spaces in the code...

While there:
*Replace a tab character in the code.
*Remove useless code.

(In reply to comment #3)
> *Use same partial-green color in header as in details.

In addition,
the initial state of the header is |background-color: green;|.
I think this should be changed to something that more clearly "says" that nothing has run yet.
What would you suggest ?

See

for a short rational.

>+    if (SimpleTest._tests.length == 0) {
>+      SimpleTest.ok(false, "[SimpleTest.report()] No checks actually run.");
>+    }

I'd like to check this in with 'true' initially:
I would then switch it to 'false' when all tests are fixed.

Nit: I'll remove the superfluous brackets.

Sorry, when I marked this as review+, I meant "it's ok with me as long as it's also ok with the other requestees".  If you were intending me to be the only reviewer, you should have said so.

Well, that was the (implicit) idea of my (desperate) comment 11 :-|

Do you want that I back it out, or simply wait for some other after-the-fact review?

I guess it's ok.

this looks pretty good. I don't really hang out in this code very often, but I like what you've done with it.

rcampbell, ping for review ?

Comment 32

[Rob Campbell [:rc] (:robcee)]

For the future, a few helpful suggestions:

"Improve mochitest* harness" doesn't tell me what you're improving, exactly. Your initial comment doesn't tell me what you intend to do and "see attached patches" requires me to read through a bunch of diffs and comments to figure out your intent.

In the future, please break these up into individual chunks of work. If you need to track a number of patches through to completion, create a dependent "tracking bug" to monitor their progress.

This allows reviewers to not have to refamiliarize themselves with an increasingly large and nebulous bug everytime a new patch arises.

Comment on attachment 384293 [details] [diff] [review]
(Ev1) browser-test.js: Improve Timeout+NoTests+Exception reports, Add NoChecks report

this is fixing problems that don't exist. It's unnecessary and a waste of review time.

Comment 34

[:Gavin Sharp [email: [e-mail]]]

Yeah, this bug has long outlived its usefulness - it's just a mess. Please file specifically targetted bugs and attach specifically targetted patches to them instead of keeping this bug rolling for anything vaguely related to test infrastructure.
