This has been integrated into https://github.com/georust/geo/tree/main/jts-test-runner
A tool used to compare the behavior of GeoRust/geo to the venerable JTS.
In particular, the contents of ./resources/testxml were copied from JTS's test files.
# Run only the centroid tests
let mut runner = TestRunner::new().matching_filename_glob("*Centroid.xml");
runner.run().expect("test cases failed");
# Run all tests
let mut runner = TestRunner::new();
runner.run().expect("test cases failed");
Not all tests are handled, in part because JTS supports a lot of things GeoRust/geo doesn't support (yet!).
For some things which are supported, GeoRust/geo might diverge. This is probably a bug, and should be investigated - precisely what this test runner is built to find!
Parsing test case input happens in OperationInput.
Each type of test (Centroid, ConcaveHull, etc.) has different inputs, so will need to be handled slightly differently.
Evaluating GeoRust/geo behavior against the expectations in the test case input happens in TestRunner#run
