Uninitialized constant in integration test

Rails
1

I am seeing weird issues when trying to create integration tests. Here
is a very simple example of something that is failing. The
assert_redirected_to, and other methods, fail with this or similar
exceptions.

I have tried requiring both ‘application’ and ‘listings_controller’, but
neither solves this problem, although the exception changes.

Anybody know what’s going on here?

Thanks.

require “#{File.dirname(FILE)}/…/test_helper”

class FooTest < ActionController::IntegrationTest
def test_redirect
get “/”
assert_redirected_to “/”
end
end

with this exception:

Slight correction. In the above case, require ‘listings_controller’
allows it to work. However if I add a second test as in this:

require “#{File.dirname(FILE)}/…/test_helper”
require ‘listings_controller’

class FooTest < ActionController::IntegrationTest

def test_redirect
get “/”
assert_redirected_to “/”
end

def test_foo
get “/”
assert_redirected_to “/”
end
end

Then I get exceptions like this:

ArgumentError (A copy of ApplicationController has been removed from the
module tree but is still active!):
