Is this a new test? Would be helpful to separate out from ported tests so I can
focus on actual new code.

+ * @constructor
+ * @extends {ChromeVoxE2ETest}
+ */
+function CvoxBrailleTableTest() {}
+
+CvoxBrailleTableTest.prototype = {
+  __proto__: ChromeVoxE2ETest.prototype,
+};
+
+/**
+ * Tests that {@code getAll} can fetch and parse the tables file.
+ * NOTE: This will need to be adjusted when more tables are added.
+ */
+TEST_F('CvoxBrailleTableTest',  'testGetAll', function() {
+  cvox.BrailleTable.getAll(function(tables) {
+    assertEquals(60, tables.length);

Define as a constant above in the class constructor.

+    assertNotNullNorUndefined(
+        cvox.BrailleTable.forId(tables, 'en-US-g1'),
+        'Can\'t find US English grade 1 table');
+    testDone();
+  });
+});
+
+/**
+ * Tests the getUncontracted function.

+TEST_F('CvoxBrailleTableTest', 'testGetUncontracted', function() {
+  cvox.BrailleTable.getAll(function(tables) {
+    function assertUncontracted(uncontractedId, idToCheck) {
+      var checkedTable = cvox.BrailleTable.forId(tables, idToCheck);
+      var uncontractedTable = cvox.BrailleTable.getUncontracted(
+          tables, checkedTable);
+      assertNotEquals(null, uncontractedTable);

[David Tseng, 2014/09/08 21:45:59]

assertNotNull? (if it exists).

+      assertEquals(uncontractedId, uncontractedTable.id);
+    }
+    assertUncontracted('en-US-comp8', 'en-US-g2');
+    assertUncontracted('en-US-comp8', 'en-US-comp8');
+    assertUncontracted('nb-comp8', 'nb-g0');

+    assertUncontracted('ar-g1', 'ar-g1');
+    assertUncontracted('de-comp8', 'de-CH-g2');
+    testDone();
+  });
+});
