Jest testing with Node - Timeout - Async callback was not invoked within the 5000ms timeout specified by...

I'm starting to test my code with Jest, and I can't make a seemingly simple test to pass. I am simply trying to check if what I receive from a Maogoose database request is an object.
The function fetchPosts() is working because I hooked it up with a React frontend and it is displaying the data correctly.
This is my function fetchPosts():
module.exports = {
fetchPosts() {
return new Promise((resolve, reject) => {
Posts.find({}).then(posts => {
if (posts) {
resolve(posts)
} else {
reject()
}
})
})
}
}
And my test:
it('should get a list of posts', function() {
return posts.fetchPosts().then(result => {
expect(typeof result).toBe('object')
})
})
This makes the test fail, and Jest says
'Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.'
QUESTION: How can I make this test pass?

You can expect asynchronous results using resolves, as shown in the Jest documentation.
In your case:
it('should get a list of posts', function() {
const result = posts.fetchPosts();
expect(result).resolves.toEqual(expect.any(Object));
})
…although I have a suspicion your list of posts is actually an array, so you probably want this:
it('should get a list of posts', function() {
const result = posts.fetchPosts();
expect(result).resolves.toEqual(expect.any(Array));
})
Another tip: You don't need to wrap the body of your fetchPost in an additional promise, you can simply return the promise you get from Posts.find and add a then to it, like this:
module.exports = {
fetchPosts() {
return Posts.find({}).then(posts => {
if (posts) {
return posts;
}
throw new Error('no posts'); // this will cause a promise rejection
})
}
}

Also if you are simply looking to increase the timeout, then you can do that by setting
jest.setTimeout(10000);You can use this statement in beforeEach if you want to change the timeout for all your tests in that describe block or in the test/it/spec block if you want it for a single test.
