I want to view output from a Heroku CI (continuous integration) test run.
CI results are visible via the Heroku Dashboard in the "Tests" tab. For this to work you need to make your tests use the TAP output format, printing to

When using the CLI, test results are available via the
heroku ci commands https://devcenter.heroku.com/articles/heroku-cli-commands#ci
