I am trying to write some integration tests in rspec/capybara/selenium for my Rails 5 app. I have recently started testing some javascript features in the app with headless Chrome.
I struck a problem where I was unable to choose a select element on the page with capybara despite this working fine when I loaded the site manually in chrome in development environment. After some investigating I figured out that the select element was not currently visible. It is hidden when the page loads but should then be made visible immediately on loading by my javascript.
I disabled headless and paused my test with a quick and dirty sleep 60
. I then looked at the javascript file in Chrome's developer tools and discovered that it has loaded an old version of the file with none of my recent changes. The file it has loaded no longer exists in my app so it must be being cached somewhere. Any ideas how this might be occurring and how I can fix it?
