如何使用 RSpec should_receive 期待一些(但不是全部)参数? [英] How to expect some (but not all) arguments with RSpec should_receive?

问题描述

class Foo
  def bar(a, b)
  ...

Foo.should_receive( :bar )

期望使用任何参数调用 bar.

expects bar to be called with any arguments.

Foo.should_receive( :bar ).with( :baz, :qux )

期望 :baz 和 :qux 作为参数传入.

expects :baz and :qux to be passed in as the params.

如何期望第一个参数等于 :baz，而不关心其他参数?

How to expect the first param to equal :baz, and not care about the other params?

推荐答案

使用 anything 匹配器:

Foo.should_receive(:bar).with(:baz, anything)
