# normalize-languages/tests
Integration tests for the normalize-languages crate.
- `query_fixtures.rs` — fixture-based tests that parse sample source files, run the six `.scm` query types (tags, calls, complexity, imports, types, decorations), and assert specific captures appear. Tests skip gracefully when grammar `.so` files are not present (`target/grammars/` absent). Build grammars with `cargo xtask build-grammars` to run them with actual grammar execution. For query types that intentionally produce zero captures (e.g. calls on languages where the query is empty), the test binds the result as `let _x = collect_captures(...)` to verify the query executes without panicking. Decoration tests use `assert_decorations_contains` to verify that language-specific decoration syntax (decorators, attributes, annotations, pragmas, doc comments) appears in captures — not just that any capture was returned.
