Currently, you cannot run tests in non-debug mode and turn on debug logging from Puppeteer that relies on https://www.npmjs.com/package/debug. Running `DEBUG=puppeteer.* ...` would also start the test runner in a debug and non headless mode. This CL renames the DEBUG variable that DevTools test runner relies on so that debug logging is independent from the debug mode we have for tests.
