A Cypress.io test suite with Istanbul-instrumented code took 30 minutes to run instead of 10. For context, we were using https://github.com/cypress-io/code-coverage.
Some overhead is expected with each spec. Collecting coverage will increase the overall run time, surely. But in debug runs (setting DEBUG=code-coverage), we saw an unexpected 31 second overhead running just one spec:
