 Description   

Certain commands, e.g., collMod, can fail with WriteConflict errors, but rarely fail with these errors in testing. A test suite should be added that prompts these errors to ensure they are handled as expected.

Comment by Maria van Keulen [ 28/Aug/19 ]

SERVER-42330 blacklists the WriteConflict-inducing workloads it adds from concurrency_simultaneous*.yml, since they presently fail because of the WriteConflict exception handling (or lack thereof) of various commands. These workloads should be un-blacklisted as part of SERVER-43053.
