instead of always returning 3, I think it would be better to create methods to set it as the rest of properties, for future tests.
So if we add it to the list 
```mProps: {'cardState': null, 'iccInfo': {}, 'retryCount': 3},```
we could be setting new values on tests with 
```
setProperty: function _setProperty(property, newState) {
    this.mProps[property] = newState;
  },
```
so your method `getCardLockRetryCount` can return `onresult(this.mProps['retryCount'];` instead
