all test suites that run on a standalone, except for:
- Unittests
*non-mongod/s C++ test suites like libfuzzer, snmp - all test suites that run on a replica set, except ones explicitly listed below
- all test suites that run on a sharded cluster, except ones explicitly listed below
- has requires_fast_memory tag (–excludeWithAnyTags=requires_fast_memory)
Â
We will make the following effort to run the above tests with undo. If the following approaches combined don't ensure the suite can run undo, we will modify the scope to exclude the failing test suites
- blacklist problematic tests, up to once time per suite (i.e. all failing tests in one patch build)
- Audit tags of failing tests or tags for performance requirements and exclude those tests
- increase the election timeout
- increase the test and task timeout
- reduce the WT cache size
- reduce the size of the cluster
- turn off continueOnFailure
- reduce the number of clients
- adjust the data size
- run on larger instances, including adding new EC2 8x instance
