🃏 Valimock

Generate mock data for Valibot schemas using Faker

---

📦 Installation

npm install --save-dev valimock @faker-js/faker

yarn add -D valimock @faker-js/faker

🔧 Usage

Import and optionally configure a new instance of the Valimock class, then pass along your valibot schema to mock(), that's it!

import { parse, array, union, string, url, number, maxValue } from "valibot";
import { Valimock } from "valimock";

describe(`example test`, () => {
  it(`should generate valid mock data`, () => {
    const schema = array(union([string([url()]), number([maxValue(20)])]));
    const result = new Valimock().mock(schema);
    expect(parse(schema, result)).toStrictEqual(result);
  });
});

Note

For async schemas, you will need to use parseAsync(). Be aware that async schemas generate a Promise and may need to be await'ed depending on usage.

Please see the __tests__ folder for more usage examples of different schema types.

API Coverage

Warning

At present, not all of valibot's API is fully covered by valimock, however, any unimplemented schema type can be handled by a user-supplied map via the customMocks configuration option. The schema's type proerty is used as the property key for this map.
