test_callable_metadata_is_sane in Cocoa bindings is very slow #535

Closed ronaldoussoren closed 1 year ago

ronaldoussoren commented 1 year ago

The test_callable_metadata_is_sane method in test_cocoa.py of the Cocoa bindings is very slow.

I expect that this cannot be fixed, this explicitly introspects every class and method in the Objective-C runtime which is known to be slow. That said, I haven't tried using a profiler with this yet to see if there's something we can do about this.

The test it still useful and at times finds problems, so won't be removed.

One thing that might be a problem: the test causes the lazy loader to load all symbols, being smarter about which symbols get loaded could help (but requires accessing internals of the lazy loader)...
