I'm using JSON schema file for form creation and validation. When I'm going to test that component, in jest testing environment all imported *.json files getting undefined.
E.g. import schema from "./schema.json" in test environment schema is undefined. Please let me know if anyone getting fixed this issue.
Thanks.
In order to import a JSON file in a Jest test, you will need to use the jest.mock function. This function allows you to mock the return value of an imported module.
Here is an example of how you can mock the ./schema.json file in your test:
jest.mock('./schema.json', () => ({ // return value for the mock }), { virtual: true }); // in your testimport schema from './schema.json'; test('my test', () => { expect(schema).toEqual({ // expected value for the mock }); });
Note that the virtual: true option is important in this case because it tells Jest to treat the file as a virtual module, rather than trying to search for it on the filesystem. This is necessary because JSON files cannot be imported directly in JavaScript and need to be handled as a special case.
