Is there a required condition?\n\n100% reproduceable.\n\n### What is the expected behavior? Why is that the expected behavior?\n\ntest runner should end after all planned tests are complete.\n\nOR\n\nit should allow me to explicitly declare my test plan so it knows after the Nth test that no more tests are gonig to be enqueued.\n\n### What do you see instead?\n\ntest runner waits for the \"beforeExit\" event before it terminates.\n\n### Additional information\n\n_No response_","author":{"url":"https://github.com/aecepoglu","@type":"Person","name":"aecepoglu"},"datePublished":"2025-02-28T10:07:35Z","url":"https://github.com/nodejs/node/issues/57234"}
