Estoy probando pruebas unitarias usando Loopback Mocha. Tengo una API POST /admin/url/createShortUrl que requiere realUrl como formdata. También algunos encabezados. Pero los encabezados parecen funcionar bien. Probé varias respuestas de stackoverflow pero ninguna funcionó. Estoy tratando de establecer el tipo de contenido como application/json , así como multipart/form-data . Pero nada de eso está funcionando.

 require('dotenv').config(); import {Client, expect} from '@loopback/testlab'; import {BrickAdminPanelApplication} from '../../application'; import upload from 'multer'; import {setupApplication} from './test-helper';

admin-panel.fuente de datos'; token const = 'eyJ0eXAiOiJKV1QiLCJhbGci';

 describe('ShortenedUrlController', () => { let app: BrickAdminPanelApplication; let client: Client; before('setupApplication', async () => { ({app, client} = await setupApplication()); }); after(async () => { await app.stop(); }); it('invokes POST /admin/url/createShortUrl', async () => { await client .post('/admin/url/createShortUrl') .set({Authorization: `Bearer ${token}`}) .set('emailId', 'myemail@gmail.com') .set('Content-Type', 'multipart/form-data') //Not working .set('Content-Type', 'application/json') //Not working .field('Content-Type', 'multipart/form-data') //Not working .field( 'actualUrl', 'https%3A%2F%2Fadminss.papers.com%2Fddqwderss1ssdadsdassatsddqposissdcsuy', ) .expect(400); }); });

ERROR
