3/3 With JSON Schema, this demo deliberately changes quantity 9 to 0. Mimlet checks for exactly one observed minimum issue at /quantity, and rejects mismatched results.

2/3 With Valibot, build() produces the input fixture: age "42". buildValidated() runs native parsing and returns numeric age 42, with the transform applied once.

7/7 A checkout bug, a smaller failing case, a fix, then a regression test.

This demo uses fast-check for generation and shrinking. Mimlet keeps declared fixture relationships together as cases are rebuilt.

6/7 Using Hey API? The separate hey-api-builders v3 alpha integration adds fluent overrides to generated model fixtures.

This demo covers model definitions and an explicit admin override.

5/7 Generate a typed builder from a factory. Use a fluent override for the admin case, then check whether the generated file has drifted.

The demo keeps source generation separate from building fixtures. Check mode does not rewrite files.

4/7 Build a mock request from an operation: path params, JSON body, method and headers.

This demo validates the runtime envelope and serializes a PATCH request locally. It does not send it.

3/7 One fixture recipe can feed a preview loader and an HTTP response resolver. Matching fresh seeded sessions produce matching values in independent objects.

This demo builds the response locally; it makes no network request.

2/7 Found a failing property? Save its replay record.

fast-check supplies seed/path replay. Mimlet checks the recipe context you provide before running it again. Keep the original source and predicate too.

1/7 From a Zod schema to a test fixture, then an admin variant. The original recipe stays unchanged.

Use buildValidated() when you want native Zod validation. Explicit invalid overrides are rejected, not repaired.
