Back in the days of
karma-browserify, a result with zero tests was an occasional transitional condition and wasn't flagged as a fatal error. See #16851 and #24957.Now, with
karma-esbuild, transformation errors can result in zero tests, and it must be flagged as a fatal error. This PR surfaces silent failures like the one in #33418 (comment).A more correct fix would be to get
karma-esbuildto throw an error when it encounters errors like the ones in #34020 (comment).
