Description

This might be a duplicate --- I searched but there were a lot of issues, hard to narrow it down effectively and quickly.

So, it's possible to work around this with multiple karma configurations, but it would be really nice if you could say "load file X if the browser is not Y or Z, otherwise load browser Ε".

Use case: loading sinon-ie as well as sinon, so that when IE runs would load the appropriate version, and non-IE runs would also load the appropriate version. This would be a kind of filtering behaviour, I guess.

I'm not really expecting this to be implemented, but it would be nice, and a lot more elegant than having per-browser karma configurations.

Research direction
Investigate how karma currently serves files to browsers. Look at the 'karma/lib/file list.js' and 'karma/lib/serve file.js' to understand the file filtering process. Check if any existing plugins (e.g., 'karma ie files') address this. Engage with maintainers to clarify if this feature aligns with the project's roadmap.
