How can I handle errors in Supertest?

How can I handle errors in Supertest?

You can handle errors in Supertest by using the .expect() method to check for specific status codes or response bodies.

Can you give me an example of how to check for a 404 error?

Sure! You can use the following code: request(app).get('/non-existent-route').expect(404); This checks if the response status is 404.

What if I want to check the error message in the response?

You can chain another .expect() to check the response body, like this: .expect(res => { if (res.body.message !== 'Not Found') throw new Error('Unexpected message'); }).

Is there a way to handle multiple error scenarios in one test?

Yes, you can use a loop or an array of test cases to handle multiple scenarios, checking each one in the same test.
