2015

[Jared Sohn, 2015/05/27 14:52:02]

Done (also changed muted.js, sinewave.js, and disable_sinewave.js; the code for
the latter two came from
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/test/data/e...)
but I am assuming the copyright should be for the year that the file was
created.)

[not at google - send to devlin, 2015/05/28 23:04:42]

Correct.

btw we also now leave the (c) out, for the record.

Open brace should be on same line as function name declaration.

[Jared Sohn, 2015/05/27 14:52:02]

Done.

+  var views = chrome.extension.getViews({type: "tab"});
+  assertEq(1, views.length);
+  var scriptElem = views[0].document.createElement("script");
+  scriptElem.type = "text/javascript";
+  scriptElem.src = filename;
+  views[0].document.body.appendChild(scriptElem);

[not at google - send to devlin, 2015/05/26 23:09:48]

Instead of this you should be able to do something like
"views[0].contentWindow.disableSinewave()" or whatever - if you define the
disableSinewave function inside the tab that you're loading, whatever that is.

And in that case, I'd compose this with a function "getOnlyTab" then call below
with getOnlyTab.disableSinewave() and getOnlyTab.enableSinewave().

[Jared Sohn, 2015/05/27 14:52:02]

Would doing this match your suggestion? 
-- create an .HTML file that gets loaded for this test (instead of the generic
one used for other tests)
-- file should include sinewave.js and expose enableSinewave and disableSinewave
functions
-- remove the disable_sinewave.js file

Sounds good to me.

kalman@'s more familiar with the JS extension testing than I am.  But, IIRC, you
should be calling chrome.test.succeed() for each function passed to
chrome.test.runTests().

[not at google - send to devlin, 2015/05/26 23:09:47]

Very confusingly, callbackPass (which pass is aliased to) calls succeed()
itself:

[Jared Sohn, 2015/05/27 14:52:02]

Correct. I am using pass here to be consistent with other tabs tests and am
using chrome.test.succeed within the tabcapture test to be consistent with those
tests.

naming nit: How about audibleUpdateAttemptShouldFail()?

Done.

[miu, 2015/05/26 21:28:46]

Not sure if it's necessary to test the state after a tab is moved between
windows, but I'm not against keeping this in the tests either.

[Jared Sohn, 2015/05/27 14:52:02]

The intention behind this test is because this patch (minimally) touches code in
TabsEventRouter::TabInsertedAt and this test gives some assurance that it wasn't
broken.

[miu, 2015/05/27 20:10:14]

Okay.  Sounds good to me.  :)
