我正在编写一个对象(Sample)的规范,它会多次调用另一个对象的方法(IO#delete)。
我想隔离这种方法的测试,但是当我这样做时:
class Sample
def delete_them
io.delete "file1"
io.delete "folder1"
end
end
describe Sample do
let(:io) { stub.as_null_object }
subject { Sample.new.tap { |s| s.stub(:io).and_return(io) }}
it "deletes file1" do
io.should_receive(:delete).with("file1")
subject.delete_them
end
it "deletes folder1" do
io.should_receive(:delete).with("folder1")
subject.delete_them
end
end
如果我调用多个方法,那不是问题,因为我使用的是空对象模式。但是,在这种情况下,当我执行第二次测试时,它会抱怨:
1) Sample instance methods#delete_them deletes folder1
Failure/Error: io.should_receive(:delete).with("folder1")
Stub received :delete with unexpected arguments
expected: ("folder1")
got: ("file1")
有没有办法表明所有的电话都必须被忽略除了我想要确定的那个?

此代码编译良好。这是造成我问题的另一个问题。
