TL;DR: CircleCI now tells you exactly which tests failed in our web UI, email notifications, and chat integrations.
CircleCI was founded on the promise of making testing less of a pain for developers, and today we’re announcing a big step forward in delivering on that promise. Most of us are used to learning of a failure on CI being the beginning of a little hunting session. We get an email or a chat message that says a build failed, and then the spelunking begins to track down the root cause. CircleCI now mitigates or removes this nuisance by displaying detailed information about which exact test cases failed in our web UI, build emails, and chat integrations.
