Summary of necessary driver changes The prose tests for Client Side Operations Timeout GridFS and endSessions have been increased from 10/15ms to 150/200ms to permit drivers with slower testing frameworks or setup times to get the expected assertions. A recommendation was added to the GridFS tests, when testing on a sharded cluster drivers may apply logic similar to the unified test format's useMultipleMongoses=false to ensure the mongos that has the fail point set is hit by the test run.
