 You can define your own `HofundConnectionsProvider` but if you want to test HTTP connection the easiest way
-is to extend `AbstractHofundBasicHttpConnection`. If your project is based on spring you can extend it like below:

 Extending `AbstractHofundBasicHttpConnection` is really simple, you only have to overrider `getTarget()`
 and `getUrl()` methods. The example above allows you to change values through spring application properties.
 
+If you want to use f.e `POST` method, you can use `new SimpleHofundHttpConnection("abc", "some_url", RequestMethod.POST)` or override `getRquestMethod()`.
+
+If you don't want to test connection in some conditions, you can use `new SimpleHofundHttpConnection("abc", "some_url", CheckingStatus.INACTIVE)` or override `getCheckingStatus()`.
