Testing Express multer Datei-Array mit Supertest laden

Question

ich einen Beitrag Endpunkt haben, die multer verwendet und nimmt eine Reihe von Dateien:

router.post('/api/projects/:id/sessions', upload.array('files', 4), function(req, res, next) { 
    ... 
} 

In Test, ich brauche eine Reihe von 4-Dateien zu senden, kann ich nicht Finde heraus, wie du das mit Supertest machst. Hier ist mein Abschaltbetriebsart Test unter Verwendung eines Verfahrens sah ich an anderer Stelle vorgeschlagen:

it('Add a session', function(done) { 
     api.post('/api/projects/' + projectId + '/sessions') 
      .set('X-Auth', tokenA) 
      .attach('files[0]', './test/files/d.zip') 
      .attach('files[1]', './test/files/m.csv') 
      .attach('files[2]', './test/files/o.15o.txt') 
      .attach('files[3]', './test/files/e.n') 
      .end(function(err, res) { 
       expect(res.status).to.equal(201) 
       done(err) 
      }) 
    }) 

Dies gibt eine ziemlich lange Fehler:

Kann mir jemand helfen, in einen Arbeits Test für diese POST Endpunkt zu schreiben? Vielen Dank.

Answer 1

So stellt sich heraus, wenn Sie nur attach Dateien auf den gleichen Namen, werden sie als solche zu einem Array und geschickt angehängt werden, so dass der Test unter funktionierte gut:

it('Add a session', function(done) { 
    api.post('/api/projects/' + projectId + '/sessions') 
     .set('X-Auth', tokenA) 
     .attach('files', './test/files/d.zip') 
     .attach('files', './test/files/m.csv') 
     .attach('files', './test/files/o.15o.txt') 
     .attach('files', './test/files/e.n') 
     .end(function(err, res) { 
      expect(res.status).to.equal(201) 
      done(err) 
     }) 
})
