Function ui_test::run_tests_generic

pub fn run_tests_generic(
    configs: Vec<Config>,
    file_filter: impl Fn(&Path, &Config) -> Option<bool> + Sync,
    per_file_config: impl Fn(&mut Config, &Path, &[u8]) + Sync,
    status_emitter: impl StatusEmitter + Send
) -> Result<()>

A version of run_tests that allows more fine-grained control over running tests.

All configs are being run in parallel. If multiple configs are provided, the Config::threads value of the first one is used; the thread count of all other configs is ignored. The file filter is supposed to return None if it was filtered because of file extensions and Some(false) if the file was rejected out of other reasons like the file path not matching a user defined filter.
