Hi everyone,Strk pointed me at the XML test suite as a good source of test data. So using Ruby, I now load the xml test cases and can run them through the SWIG bindings which use the c api.
To do this, however, requires adding 2 methods to the C API.The first method is Geometry::normalize which converts a geometry to its cannonincal form. Without this method, the results from performing operations (like buffer) will be in some undetermined order and thus the test fails since the actual result does not match the expected result. Since this seems to be a generally useful method I'd like to add in to the C API.
The second method is one I mentioned the other day, equalsExact. The XMLTestRunner uses this method to verify that the expected and actual results match. Unfortunately, using equals does not work since it returns false in some cases where equalsExact returns true (you can set a tolerance with equalsExact). Once again, this seems like a generally useful method so I'd also like to add in to the C API.
On my local box I have added both of these methods to the C API, and the SWIG bindings now generate the same results as the C++ API (i've only done some of the tests so far).
Note that a number of the XML test cases fail using either API. For example, in buffer.xml roughly half the tests fail. Is this a problem?
