Snapshot tests are written using the .toMatchSnapshot() matcher:
import { test, expect } from "bun:test";
test("snap", () => {
expect("foo").toMatchSnapshot();
});
The first time this test is run, the argument to expect will be serialized and written to a special snapshot file in a __snapshots__ directory alongside the test file. On future runs, the argument is compared against the snapshot on disk. Snapshots can be re-generated with the following command:
$ bun test --update-snapshots
