@einzigsue can you take a look at the failing test as well?

[einzigsue]

In order to get all current unit tests passing, I’ll need to update at lease three of them, namely,

• test_artifacts_integration.py
• test_artifacts.py
• test_evaluator_timeout.py

Would you like me to include these test updates in the same PR?

According to my current understanding, the failing unit tests for config files/examples are caused by a mismatch with the new Evaluator API interface in the PR. Specifically, the updated Evaluator now needs to be aware of the file extension of the initial program to create the temporary file with the same extension. To address this, I will need to pass the file suffix into the Evaluator in all the affected unit test so it can initiate the evaluator correctly. For example, modify code here https://github.com/codelion/openevolve/blob/ddf42e265fb10917f251c8609f3cb3ebef3759c0/tests/test_artifacts.py#L157

to match the new API.

@einzigsue can we fall back to the default py extension if it is not specified this should help ensure existing examples all run as is.
