- Steelreed reports QueryFence checked 75 statements in a dogfood test, finding 15 real leaks and four false alarms.
Field notes
Cronbell's example alert records the missed 02:00 run, the previous successful run at 02:00 the day before, and its 38-second duration. QueryFence is listed as a Spring test library under the Maven coordinate com.steelreed:queryfence-spring-test; the reported leak and false-alarm counts come from Steelreed's own dogfood test.
