stub with argument constraints

You can further specify the behavior by constraining the type,
format and/or number of arguments with the #with() method
chained off of #stub()

Scenarios

an_instance_of argument matcher

Given

a file named "stub_an_instance_of_args_spec.rb" with:

describe "stubbed an_instance_of() args spec" do
  it "works" do
    object = Object.new
    object.stub(:foo).with(an_instance_of(Symbol)) do
      "symbol"
    end
    object.stub(:foo).with(an_instance_of(String)) do
      "string"
    end

    object.foo("bar").should eq("string")
    object.foo(:that).should eq("symbol")
  end
end

When

I run rspec stub_an_instance_of_args_spec.rb

Then

the output should contain "1 example, 0 failures"
