it could be nice to write this like

chrome.extension.getViews().forEach(function(view) {
  view.pass = true;
});

[ericzeng, 2014/07/18 19:37:05]

Done.

+for (var i = 0; i < windows.length; ++i)
+  windows[i].pass = true;
+chrome.runtime.sendMessage('hi');

nice test :)

we should also add a test that the options page actually gets, and can call,
privileged APIs. it can clearly call unprivileged APIs because sendMessage is
unprivileged. a fairly simple way of doing that would be to:
1- make the extension request the "storage" permission
2- make the options page call

var pass = chrome.test.callbackPass;

chrome.storage.local.set({'test': 42}, pass(function() {
  chrome.storage.local.get('test', pass(function(storage) {
    chrome.test.assertEq(42, storage.test);
  }));
});

chrome.test.listenOnce(chrome.storage.onChanged, function(change) {
  chrome.test.assertEq(42, change.test.newValue);
});
