tests-integration — Agent & Contributor Guide

Integration test modules are registered in tests/main.rs (autotests = false). Shared instance and storage helpers live in src/instance.rs and src/test_util.rs. See README.md for external-service setup.

Import/export portability

Import/export and COPY tests must work on Windows as well as Linux/macOS. #9227 records export tests failing because native Windows paths were compared with /-separated COPY locations.

• Keep native filesystem paths (Path/PathBuf), file URIs, and /-separated object-store keys distinct. Compare filesystem paths as paths; for COPY location assertions, normalize both sides to the defined location format. Do not compare native PathBuf::join().display() strings directly with /-separated export locations.
• Build filesystem fixtures with temporary directories and convert absolute paths to file URIs with Url::from_file_path; do not hard-code /tmp or concatenate file:// with native paths. Close file handles before rename or cleanup, including import-state writes.

Validation

Run focused cases from the repository root:

cargo nextest run -p tests-integration --test main -E 'test(<test-name>)'

For import/export changes, run affected tests on Windows. The reference job is test-on-windows in Nightly CI (cargo nextest run -F dashboard). Linux/macOS success does not establish Windows compatibility. If Windows execution is unavailable, explicitly report that gap and inspect platform-specific paths and file operations.
