Dynamic Method Handling

Class Method Details

.send(method, *args) ⇒ Object

Override the send method.

This was implemented to cover the case where test is used as a state. In that case, the default behavior was to call the private test method from Kernel. This prevents that behavior in cases where a public method is available via method_missing in the parent class.
