--------------------------------
Summary: Fail benchmark junit tests if their numbers deviate too
far from a baseline
Key: GEODE-6147
URL: https://issues.apache.org/jira/browse/GEODE-6147
Project: Geode
Issue Type: Improvement
Components: benchmarks
Reporter: Dan Smith
We want to fail tests if performance gets worse. We also want a signal to
create a new baseline if performance gets better, so perhaps we should fail
tests in that case as well.
One way to do this would be to add a new system property to the
TestRunners.defaultRunner() that takes in a baseline directory. The test itself
could compare it's results with the baseline after running and fail if it
deviates too far from the baseline.
Using that, we could a new flag to the benchmark task to pass in that baseline
and cause tests that deviate to fail.
Eg
./gradlew benchmark -Pbaseline=/some/dir
Acceptance:
run_against_baseline.sh generates a failure report if benchmarks deviate too
far from the baseline.
