# Description of Changes HTTP handlers already have smoketest coverage, but in order to add to `module-test`s all languages had to have parity as `module-test` has a check to ensure schemas match. The existing integration tests using `module-test` load SpacetimeDB in memory, expanding these tests would require significant and potentially ugly work to handle hosting for HTTP handlers. Instead, this PR adds compile-only for each `module-test` with a matching handler + route. # API and ABI breaking changes N/A # Expected complexity level and risk 1 - tiny addition to `module-test` for all languages # Testing - [x] `cargo test -p spacetimedb-schema module_test` - [x] `cargo test -p spacetimedb-testing`
