Testing

First, make sure docker compose is running (from main posthog repo), and test database exists:

docker compose -f ../docker-compose.dev.yml up -d

TEST=1 python manage.py setup_test_environment --only-postgres

We only need to run the above once, when the test database is created.

TODO: Would be nice to make the above automatic.

Then, run the tests:

cargo test --package feature-flags

To watch changes

brew install cargo-watch

and then run:

cargo watch -x test --package feature-flags

To run a specific test:

cargo watch -x "test --package feature-flags --lib -- property_matching::tests::test_match_properties_math_operators --exact --show-output"

Running

RUST_LOG=debug cargo run --bin feature-flags

Format code

cargo fmt --package feature-flags
