NoMethodError: undefined method `stub' for ModuleX:Module

Using Mocha, I am trying to mock a controller method that calls a module method. This is for an integration test.

Example:

class Controller < ApplicationController
  def method1
    response = Module1.method2(...

My steps so far:

Is it possible to stub method2?

EDIT: So the main fix is that the method is 'stubs' not 'stub'. I'm still having trouble mocking this dang Module though.

EDIT: Rails and MiniTest just call the module method even after I've stubbed it. Is it possible that Rails is overwriting my stub?

class Test < ActionDispatch::IntegrationTest

test "test do

Module1.stubs(:method2).returns(:true)
post "controller/method1"

This test leads to error inside method2 bc no parameters were passed in. The test is behaving as if the method was not stubbed.

for me this was caused by not adding require 'minitest/mock' to my test_helper.rb

regarding your test you may want a

Module1.expects(:method2)

but the stub should work anyway. Rails would not overrite your stub, maybe you test_helper does, but i'm quite sure it is more a syntax thing.

Paste your real code and test because here right know it's kind of difficult and can be anything... a callback preveting the method to be called, the test syntax, ...

try .stubs with an s.

The stubnotation is to build a stub you'lle use later on. Add an s when you stub a method directly on something.
