这是我正在测试的类,包含在Foo.rb中:

class Foo
    def bar
        return 2
    end
end

这是我在Foo_spec.rb中包含的测试:

require "./Foo.rb"

describe "Foo" do
    before(:all) do
        puts "#{Foo == nil}"
        Foo.any_instance.stub(:bar).and_return(1)
    end

    it "should pass this" do
        f = Foo.new
        f.bar.should eq 1
    end
end

我得到以下输出:

false
F
