【问题描述】：

我正在对 RSpec 中的控制器方法进行存根，并且存根工作正常，但我如何确保使用特定输入调用该方法，即我传递给调用此存根方法的方法的哈希？

【解决方案1】：

您可以使用 expect_to_receive_with_arguments：

expect(double).to receive(:msg).with(no_args)
expect(double).to receive(:msg).with(any_args)
expect(double).to receive(:msg).with(1, any_args) # any args acts like an arg splat and can go anywhere
expect(double).to receive(:msg).with(1, kind_of(Numeric), "b") #2nd argument can be any kind of Numeric
expect(double).to receive(:msg).with(1, boolean(), "b") #2nd argument can be true or false
expect(double).to receive(:msg).with(1, /abc/, "b") #2nd argument can be any String matching the submitted Regexp
expect(double).to receive(:msg).with(1, anything(), "b") #2nd argument can be anything at all
expect(double).to receive(:msg).with(1, duck_type(:abs, :div), "b") #2nd argument can be object that responds to #abs and #div
expect(double).to receive(:msg).with(hash_including(:a => 5)) # first arg is a hash with a: 5 as one of the key-values
expect(double).to receive(:msg).with(array_including(5)) # first arg is an array with 5 as one of the key-values
expect(double).to receive(:msg).with(hash_excluding(:a => 5)) # first arg is a hash without a: 5 as one of the key-values

【解决方案2】：

#with 方法正是您想要的。
跟随例子here:
expect(double).to receive(:stubbed_method).with(hash_argument)
