Shouldn't we add tests here for the interactivity modes?

[Evan Stade, 2012/07/20 19:48:13]

it would currently fail any test because the prompt's not implemented, and when
it is implemented it's hard to test things that require user interaction. The
only thing we could test is the types, which I can add if you want but that
style of test doesn't seem to exist in this file.

 
-  function openMediaGalleryManager() {
-    // Just confirm that the function exists.
-    chrome.test.assertTrue(mediaGalleries.openMediaGalleryManager !== null);
-    chrome.test.succeed()
-  },
-
   function extractEmbeddedThumbnails() {
     var result = mediaGalleries.extractEmbeddedThumbnails({});
     chrome.test.assertEq(null, result);
-    chrome.test.succeed()
+    chrome.test.succeed();
   },
 
   function assembleMediaFile() {
     mediaGalleries.assembleMediaFile(
-        {}, {}, chrome.test.callbackPass(nullCallback));
+        {'mediaFileContents': {}, 'metadata': {}},
+        chrome.test.callbackPass(nullCallback));
   },
 ]);
