+/**
+ * Test Definition
+ *
+ * Most tests can use an array named TESTS that will perform most if not all of
+ * the necessary checks. Each element in the array must be an object with the
+ * following possible properties. Additional properties besides the ones listed
+ * below can be added as needed.
+ *
+ * overrideCallback (optional)
+ *   The function to call for the next test. This is typically called when the
+ *   wizard page changes but can also be called for other events by the previous
+ *   test. If this property isn't defined then the defaultCallback function will
+ *   be called. If this property is defined then all other properties are
+ *   optional.
+ *
+ * pageid (required unless overrideCallback is specified)
+ *   The expected pageid for the wizard. This property is required unless the
+ *   overrideCallback property is defined.
+ *
+ * extraStartFunction (optional)
+ *   The function to call at the beginning of the defaultCallback function. If
+ *   the function returns true the defaultCallback function will return early
+ *   which allows waiting for a specific condition to be evaluated in the
+ *   function specified in the extraStartFunction property before continuing
+ *   with the test.
+ *
+ * extraCheckFunction (optional)
+ *   The function to call to perform extra checks in the defaultCallback
+ *   function.
+ *
+ * extraDelayedCheckFunction (optional)
+ *   The function to call to perform extra checks in the delayedDefaultCallback
+ *   function.
+ *
+ * buttonStates (optional)
+ *   A javascript object representing the expected hidden and disabled attribute
+ *   values for the buttons of the current wizard page. The values are checked
+ *   in the delayedDefaultCallback function. For information about the structure
+ *   of this object refer to the getExpectedButtonStates and checkButtonStates
+ *   functions.
+ *
+ * buttonClick (optional)
+ *   The current wizard page button to click at the end of the
+ *   delayedDefaultCallback function. If the buttonClick property is defined
+ *   then the extraDelayedFinishFunction property can't be specified due to race
+ *   conditions in some of the tests and if both of them are specified the test
+ *   will intentionally throw.
+ *
+ * extraDelayedFinishFunction (optional)
+ *   The function to call at the end of the delayedDefaultCallback function.
+ *   If the extraDelayedFinishFunction property is defined then the buttonClick
+ *   property can't be specified due to race conditions in some of the tests and
+ *   if both of them are specified the test will intentionally throw.
+ *
+ * ranTest (should not be specified)
+ *   When delayedDefaultCallback is called a property named ranTest is added to
+ *   the current test so it is possible to verify that each test in the TESTS
+ *   array has ran.
+ *
+ * prefHasUserValue (optional)
+ *   For comparing the expected value defined by this property with the return
+ *   value of prefHasUserValue using gPrefToCheck for the preference name in the
+ *   checkPrefHasUserValue function.
