Running minimized Agg fuzzer and Query fuzzer tests locally

Usage

If there is an agg or query fuzzer-generated test failure, a minimized jstestfuzz test will be generated from the original to reduce test size & complexity. Minimized jstestfuzz tests & minimized data will be available for download in the files section in the Evergreen task page displayed as:

1. Minimized jstestfuzz Test - [Execution #]
   • minimizer-outputs-minimizedtest-[build_id].js
2. Minimizer Outputs - [Execution #]
   • minimizer-outputs-[build_id].json

You can run the minimized test with the following command after setting up a repro environment:

buildscripts/resmoke.py run --suites=generational_fuzzer['', _last_lts, _last_continuous] /local/path/to/minimized/test/minimizer-outputs-minimizedtest-[build_id].js

If the above does not work, you can find the exact resmoke invocation by searching for the string "resmoke.py invocation for local usage" in the "Task Logs" and add the local file path to the minimized test as a positional argument.

Known Limitations

• The minimizer is not run with the timeseries fuzzer due to incompatibility with time series collections.

Notes

For more information on running tests from Evergreen locally, see the Wiki: Running Tests from Evergreen Tasks Locally.

If the minimized output is not available or incorrect for Agg and Query fuzzers please reach out to #server-testing.
