I've searched a lot and just cannot figure this out although it seems basic. Here's a way simplified example of what I want to do.
Create a simple method that does something but doesn't return anything, such as:
class Test
def test_method(param)
puts param
end
test_method("hello")
end
But in my rspec test I need to pass a different parameter, such as "goodbye" instead of "hello." I know this has to do with stubs and mocks, and I've looking over the documentation but can't figure it out: https://relishapp.com/rspec/rspec-mocks/v/3-0/docs/method-stubs
If I do:
@test = Test.new
allow(@test).to_receive(:test_method).with("goodbye")
it tells me to stub out a default value but I can't figure out how to do it correctly.
Error message:
received :test_method with unexpected arguments
expected: ("hello")
got: ("goodbye")
Please stub a default value first if message might be received with other args as well.
I am using rspec 3.0, and calling something like
@test.stub(:test_method)
is not allowed.
How to set a default value that is explained at
and_call_original
can configure a default response that can be overriden for specific args
require 'calculator'
RSpec.describe "and_call_original" do
it "can be overriden for specific arguments using #with" do
allow(Calculator).to receive(:add).and_call_original
allow(Calculator).to receive(:add).with(2, 3).and_return(-5)
expect(Calculator.add(2, 2)).to eq(4)
expect(Calculator.add(2, 3)).to eq(-5)
end
end
