It powers spectral analysis, coordinate transforms, time parsing, and cosmological calculations used by researchers worldwide.</p> <h2> The Problem </h2> <p>Astropy has C and Cython extensions that handle performance-critical operations. These are currently tested only indirectly through the public Python API. A bug in the compiled layer can sit undetected for a long time. My project aims to build a direct, low-level test suite for these extensions.</p> <h2> What I've Done So Far </h2> <p>I've already contributed 12 PRs to Astropy, with 8 merged, including:</p> <ul> <li>Found and fixed a missing <code>goto fail</code> in <code>parse_times.c</code> </li> <li>Added direct tests for the <code>scalar_inv_efuncs</code> Cython extension</li> <li>Fixed bugs in stats, units, table, and time subpackages</li> </ul> <h2> What's Next </h2> <p>During GSoC I'll extend this test suite to cover all major C/Cython extensions across time, stats, cosmology, coordinates, table, and wcs subpackages — making Astropy's compiled layer independently testable for the first time.</p> gsoc opensource python astropy
