I encountered the following head-scratcher when trying to run the following RSpec test on MacOs:
➜ bundle exec rspec ./spec/features/some_spec.rb:12
Capybara starting Puma…
Version 4.3.8 , codename: Mysterious Traveller
Min threads: 0, max threads: 4
Listening on tcp://127.0.0.1:63422
unexpected response, code=500, content-type="text/html"
Host header or origin header is specified and is not whitelisted or localhost.
After much fruitless poking around in
./spec/rails_helper.rb, I checked my
/etc/hosts file and realised I had mapped 127.0.0.1 to a custom name. I updated
/etc/hosts to include only the following lines:
And hey presto, Selenium would now run the rest of my (still failing) tests.
As an aside, I tried passing the options
'--headless', '--disable-web-security', '-–allow-file-access-from-files', '--allowed-origins=*‘ to Capybara in ./spec/rails_helper.rb, and none seemed to have any effect.
