Feature Flag consistency tests

Overview

These tests aim to ensure that a different feature flag configuration produces the same results.

Getting started

To launch the tests using mzcompose, run

bin/mzcompose --find feature-flag-consistency down -v && bin/mzcompose --find feature-flag-consistency run default

To start the tests from a shell, use

bin/feature-flag-consistency --max-runtime-in-sec 60

Test explain plans

This can be done using the --output-query-mode parameter. Refer to the version-consistency test for more details.

Query generation

Queries are generated using the output consistency test framework, which is also used to ensure consistency between data-flow rendering and constant folding evaluations. See this README for more details on query generation.

To ignore known inconsistencies, extend the FeatureFlagConsistencyIgnoreFilter.
