J'ai le code suivant pour mes tests avec Sinon et Mocha. Chaque fois que je lance ces tests, je reçois le texte suivant RetourTests Mocha et Sinon avec Promesses Timeout
0 passing (747ms) 8 pending 1 failing 1) Customer displays order Given that the order is empty "before each" hook for "will show no order items": Error: Timeout of 500ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
Les tests ont été passent jusqu'à ce que je commencé à intégrer les promesses dans l'image et de faire des tests plus réalistes, par exemple, mis en place pour traiter asynchrone appels. Qu'est-ce que je fais de mal et comment puis-je faire passer les tests?
