can you take the verification in these tests a bit further, and verify that
something actually shows?  Better still if we can verify that what shows is what
we expect.

Once I have some c++ code in there, I intend to add more testing around the
actual behavior.  Unfortunately the JS can't currently determine what actually
is in the system tray.

+  function showAndHideNonexistentIcon() {
+    // Hide before show, just in case
+    chrome.experimental.systemIndicator.hide();
+    chrome.experimental.systemIndicator.show();
+    chrome.experimental.systemIndicator.hide();
+    chrome.test.succeed();
+  },
+  function setUrl() {
+    // Success in showing the icon?
+    chrome.experimental.systemIndicator.setURL('128.png');
+    chrome.test.succeed();
+  },
+  function setImageData() {
+    // create a canvas, then set the icon using it.
+    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 imageData = canvas_context.getImageData(0, 0, 20, 20);
+    chrome.experimental.systemIndicator.setImageData(imageData);
+    chrome.test.succeed();
+  }
+]);
