Do other tests have this? It seems unnecessary to me, generally people know how
to use --gtest_filter. I guess it might be useful saying that this test's
companion is in system_indicator_apitest.cc though.

The test I first modeled this test after did have it, but I see that many others
don't.  I'm fine removing it.

+var callback = function() {

unused?

[dewittj, 2012/11/27 01:53:55]

Removed, replaced by callbackPass.

+  if (chrome.runtime.lastError) {
+    console.log('Error detected:' + chrome.runtime.lastError);
+    chrome.test.fail();
+  } else {
+    chrome.test.succeed();
+  }
+};
+
+// TODO(dewittj) Add binary files before adding setUrl tests.
+chrome.test.runTests([
+  function setIconAndShow() {
+    var canvas = document.createElement('canvas');
+    canvas.width = 20;
+    canvas.height = 20;
+
+    var canvas_context = canvas.getContext('2d');
+    canvas_context.clearRect(0, 0, 20, 20);
+    canvas_context.fillStyle = '#00FF00';
+    canvas_context.fillRect(5, 5, 15, 15);
+    var data = canvas_context.getImageData(0, 0, 19, 19);
+    chrome.systemIndicator.setIcon({ imageData: data }, function () {

use callbackPass here (see chrome/renderer/resources/extensions/apitest.js) like

chrome.sI.setIcon(..., chrome.test.callbackPass(function() {
  chrome.sI.enable();
  chrome.sI.disable();
}));

it will do the lastError check for you, and automatically call
chrome.test.succeed afterwards.

[dewittj, 2012/11/27 01:53:55]

Done.

+      if (chrome.runtime.lastError) {
+        console.log('Error detected:' + chrome.runtime.lastError);
+        chrome.test.fail();
+      }
+      chrome.systemIndicator.enable();
+      chrome.systemIndicator.disable();
+      chrome.test.succeed();
+    })
+  }
+]);
