Function run_tests_with_session 

pub fn run_tests_with_session<'a>(
    path: &'a Path,
    options: &'a RunOptions,
    session: &'a TestRunSession,
) -> Pin<Box<dyn Future<Output = TestSummary> + 'a>>

Run tests while retaining immutable prepared-module artifacts in session.

Callers that execute only once should use run_tests_with_options. Watch mode and long-lived hosts should retain one session for their desired cache lifetime and inspect TestRunSession::stats for reuse receipts.
