mongo-java-driver Validation Report

Generated 2026-05-10 — SecantusDB 0.5.0b2 vs mongo-java-driver cb45be6bb147 (vendor/mongo-java-driver/).

Run uv run python -m invoke validate-java to refresh. The pass rate is the analogue of the pymongo / mongo-go-driver / mongo-node-driver gauges for the official Java driver — the language enterprise MongoDB consumers most often use.

How this is generated

mongo-java-driver’s tests are run unmodified, against a standalone SecantusDB daemon. The submodule at vendor/mongo-java-driver/ is checked out at the pinned upstream tag with zero local edits. java_validation/runner.py does a two-phase spawn: phase 1 boots python -m secantus --port 27018 --storage-path <tempdir> --standalone without --auth and uses pymongo to createUser root-user (root role); phase 2 stops that daemon and restarts on the same tempdir with --auth, so the user record persists and the server now enforces auth. Gradle then runs the driver’s bundled wrapper (./gradlew --no-daemon -Dorg.mongodb.test.uri=mongodb://root-user:password@127.0.0.1:27018/?authSource=admin) for the in-scope modules in java_validation/include_modules.py. The system property is the seam Java’s ClusterFixture test infrastructure reads; Gradle forwards it to the test JVM. Standalone topology is critical: without --standalone the driver’s getSecondary() is an unbounded sleep loop on non-RS deployments.

These are integration specs under driver-sync/src/test/functional/ — every test opens a real TCP connection to the SecantusDB daemon, SCRAM-authenticates, and exchanges wire commands end-to-end. The pass rate is therefore a true measure of SecantusDB’s compatibility with the Java driver, not of the driver’s own pure-code logic.

The include set is currently narrow on purpose — MongoCollectionTest, MongoClientTest, ExplainTest, ReadConcernTest, MongoWriteConcernWithResponseExceptionTest — added one at a time as each is proven to terminate against SecantusDB. The driver writes JUnit XML to <module>/build/test-results/test/TEST-*.xml; we copy those out of the vendored tree (so the submodule stays untouched) and parse them here. Widen include_modules.py to add more test classes.
