How to fix 'Too many open files' error in RSpec & Capybara?
Errno::EMFILE: Failed to open TCP connection to 127.0.0.1:9515 (Too many open files - socket(2) for "127.0.0.1" port 9515)
ulimit -Sn 10240 in bash, the underlying error becomes visible. For me, this was:
Failure/Error: expect(page).to have_content 'Some text' expected to find text "Some text" in "Some other text"
