Question

I have a remote form, which disables the submit button while the AJAX request is in progress. I’d like to check that if I stress click the button, no other AJAX requests will be done. How could I check this in an integration test?

Answer 1

you can check active ajax calls with jquery

$.active

If you use capybara for integration tests

page.evaluate_script('$.active').should be <= 1

might be a solution.

As you probably don’t know when calls occur
a helper function might do the trick

def test_until(seconds=5)
  start_time = Time.now
  while (Time.now - start_time) <= seconds do
    yield
    sleep 0.05
  end
end

wich can be called like this

test_until do
  page.evaluate_script('$.active').should be <= 1
end

Thus you test for 5 seconds if there are ever more than one active ajax call
