{ expect({ foo: "bar" }).toMatchSnapshot(); }); The first time this test is executed, Bun will write a snapshot file to disk in a directory called __snapshots__ that lives alongside the test file. File TreeCopytest ├── __snapshots__ │   └── snap.test.ts.snap └── snap.test.ts To regenerate snapshots, use the --update-snapshots flag. terminalCopybun test --update-snapshots Copytest/snap.test.ts: ✓ snapshot [0.86ms] 1 pass 0 fail snapshots: +1 added # the snapshot was regenerated 1 expect() calls Ran 1 tests across 1 files. [102.00ms] See Docs > Test Runner > Snapshots for complete documentation on snapshots with the Bun test runner.
