I have the following class method in my Sequelize model:
getById(id) {
return new Promise((resolve, reject) => {
var Conference = sequelize.models.conference;
Conference.findById(id).then(function(conference) {
if (_.isObject(conference)) {
resolve(conference);
} else {
throw new ResourceNotFound(conference.name, {id: id});
}
}).catch(function(err) {
reject(err);
});
});
}
Now I want to test my method with chai. But now when I do Conference.getById(confereceId) I get the following back:
Promise {
_bitField: 0,
_fulfillmentHandler0: undefined,
_rejectionHandler0: undefined,
_promise0: undefined,
_receiver0: undefined }
Is this right and how do I assert the result of it with chai?
Your Conference.getById(confereceId) call returns a promise, so you should resolve the promise first via then, and assert the result of it with chai like this:
const assert = require('chai').assert;
Conference
.getById(confereceId)
.then(conf => {
assert.isObject(conf);
// ...other assertions
}, err => {
assert.isOk(false, 'conference not found!');
// no conference found, fail assertion when it should be there
});
