Class: RR::Injections::DoubleInjection
- Defined in:
- lib/rr/injections/double_injection.rb
Overview
RR::DoubleInjection is the binding of an subject and a method. A double_injection has 0 to many Double objects. Each Double has Argument Expectations and Times called Expectations.
Defined Under Namespace
Classes: MethodArguments
