camel-test 0.7.2

//! Integration tests for validator (XSD mode) using the xml-bridge binary.
//!
//! **Requires `integration-tests` feature:** `cargo test -p camel-test --features integration-tests`
//! **Requires the xml-bridge binary.** Build it with:
//!   `cd bridges/xml && ./build-native.sh`
//! Or set `CAMEL_XML_BRIDGE_BINARY_PATH` / `XML_BRIDGE_PATH` to the binary path.
