This PR does not seem to contain any modification to coverable code. |
Enables support for using ccache when running C++ tests. This allows unchanged compiled object files to be pulled from the cache, speeding up testing when the C++ files have not changed. This results in a 62% reduction in test time when no C++ files have changed

There was a problem hiding this comment.
I'm not entirely understand the mechanism of ccache but the structure overall looks good to me

@bact For an example, since C++ was the longest test suite, the entire runtime of https://github.com/JPEWdev/shacl2code/actions/runs/31742427011 completed in about 8 minutes (down from 12 minutes), and this wasn't even an ideal case since that PR actually modifies C++ code. The C++ and jsonschema tests now take about the same time. |
