+/**
+ * Mock implementation of {@link angular.service.$log} that gathers all logged messages in arrays
+ * (one array per logging level). These arrays are exposed as `logs` property of each of the
+ * level-specific log function, e.g. for level `error` the array is exposed as
+ * `$logMock.error.logs`
+ *
+ * Please note that this is not a factory function, but rather the actual mock instance. This is
+ * important because it allows `beforeEach` and `afterEach` test hooks to clean up or check the
+ * state of `logs` arrays in between tests.
+ *
+ * Exposing the instance in this way makes this mock a singleton, which means that the instance
+ * becomes global state for tests. To mitigate the issue, each time the `$log` mock is registered
+ * with the injector, a check is performed to ensure that there are no pending logs in `logs`
+ * arrays. This means that if a message is logged via $log during a test, the `logs` array must be
+ * emptied before the test is finished. `Array#shift` method can be used for this purpose as
+ * follows:
+ *
+ * <pre>
+ *   it('should do some good', function() {
+ *     var scope = angular.scope(),
+ *         $log = scope.$service('$log');
+ *
+ *     //do something that triggers a message to be logged
+ *     expect($log.error.logs.shift()).toEqual(['message', 'arg1', 'arg2']);
+ *   });
+ * </pre>
+ *
+ * See {@link angular.mock} for more info on angular mocks.
