具有指定参数的RSpec测试方法

Question

I am try testing a method call that receive a named argument, like this:

expect(@fake_task_search).to receive(:search).with({:query=>"a"})
        @repo.all({query:  "a"})

And the SUT

def all(params)
  @search_task.search(query: params[:query]).load
end

When I ran this I receive this:w rong number of arguments (0 for 1).

Any help will be great.

Thanks

Answer 1

Call matcher the same way you call method .with(query: "a")

class Repo
  def initialize(search_task)
    @search_task = search_task
  end

  def all(params)
    @search_task.search(query: params[:query])
  end
end

it "calls" do
  @search_task = SearchTask.new
  @repo = Repo.new(@search_task)

  expect(@search_task).to receive(:search).with(query: "a")

  @repo.all({query:  "a"})
end
