explicit arguments

Allows you to explicitly specify the argument values

Scenarios

Given

a file named "stub_explicit_args_spec.rb" with:

describe "stubbed explicit arguments" do
  it "works on stubs" do
    object = Object.new
    object.stub(:foo).with(:this) do |arg|
      "got this"
    end
    object.stub(:foo).with(:that) do |arg|
      "got that"
    end

    object.foo(:this).should eq("got this")
    object.foo(:that).should eq("got that")
  end

  it "works on doubles and expectations" do
    object = double('foo')
    object.should_receive(:bar).with(:foo)

    object.bar(:foo)
  end
end

When

I run rspec stub_explicit_args_spec.rb

Then

the output should contain "2 examples, 0 failures"

explicit arguments with multiple arities

Given

a file named "stub_multiple_explicit_args_spec.rb" with:

describe "stubbed multiple explicit arguments" do
  it "works on stubs" do
    object = Object.new
    object.stub(:foo).with(:this) do |arg|
      "got this"
    end
    object.stub(:foo).with(:this, :that) do |arg1, arg2|
      "got this and that"
    end

    object.foo(:this).should eq("got this")
    object.foo(:this, :that).should eq("got this and that")
  end
  
  it "works on mocks" do
    object = double('foo')
    object.should_receive(:foo).with(:this, :that)

    object.foo(:this, :that)
  end
end

When

I run rspec stub_multiple_explicit_args_spec.rb

Then

the output should contain "2 examples, 0 failures"
