Expect method not to be called by default

Let's say there's a method report defined on ErrorReporter module. In my RSpec test suite I'd like to somehow globally stub this method so that test fails if it's not explicitly expected to receive this message.

For instance, this test

expect "responds with HTTP 200 OK" do
  perform_request # calls ErrorReporter.report somewhere

  expect(response).to have_http_status(:ok)
end

should fail if perform_request invokes ErrorReporter.report.

And this test

expect "responds with HTTP 200 OK" do
  perform_request # calls ErrorReporter.report somewhere

  expect(response).to have_http_status(:ok)
  expect(ErrorReporter).to have_received(:report).with(...).once # explicit expectation
end

does not fail because we defined explicit have_received expectation.

I want something like this:

# spec_helper.rb

config.before(:each) do
  allow(ErrorReporter).to receive(:report).and_return(true)
end

config.after(:each) do
  expect(ErrorReporter).not_to have_received(:report) # disallow by default
end

but it fails with error "ErrorReporter expected to have received report, but that method has been mocked instead of stubbed or spied."
