# Backend Mocking The backend _must_ be mocked using fixtures or other methods. You can use ```typescript cy.interceptMultiSearch(...) cy.interceptSearch({extend: 'fixture', fixture: 'fixture', alias: 'alias'}) cy.interceptGet({uid}) ``` For mocking the responses based on a request. Paths in the commands will be relative to those, so `cy.interceptSearch({extend: 'request', fixture: 'response'})` will actually pull the fixtures from `request.search.req.json` and `response.search.res.json` respectively. If `fixture` is omitted, an empty response will be returned.
