如何使用 rspec 测试 controller 方法？

Question

I'm trying to learn rspec. I can't seem to test a rails controller method. When I call the method in the test, rspec just returns an undefined method error. Here is my test example

it 'should return 99 if large' do
  GamesController.testme(1000).should == 99
end

and here is the error:

 Failure/Error: GamesController.testme(1000).should == 99
 NoMethodError:
   undefined method `testme' for GamesController:Class

I do have a testme method in the GamesController. I don't understand why the test code cannot see my methods.

Any help is appreciated.

Answer 1

I think the correct way is this:

describe GamesController do
  it 'should return 99 if large' do
    controller.testme(1000).should == 99
  end
end

In a rails controller spec, when you put the controller class in describe , you can use controller method to get an instance:P
Obviously, if testme method is private, you still have to use controller.send:testme

Answer 2

You try to test class method, but controller has instance method

You need GamesController.new.testme(1000).should == 99

Or even GamesController.new.send(:testme, 1000).should == 99 , because, as I think, this is not action method, but private or protected.

Action methods are tested this way
