Supertest shows passing when it should fail

Question

Here is the output from morgan

::ffff:127.0.0.1 - - [01/Dec/2016:23:44:19 +0000] "GET /temp HTTP/1.1" 404 17 "-" "node-superagent/2.3.0"

And the tests that i have written are

var chai    = require("chai");
var request = require('supertest');
var server  = require("../app");

describe("Basic tests", function() {
  describe("Check if server is running", function() {
    it("Root endpoint returns 200", function() {
      request(server)
        .get('/temp')
        .expect(200)
        .end();
    });
  });
});

The morgan is showing 404 code that i can also confirm by passing a function in end() but the test are running fine in mocha with no errors. Where am i going wrong ?

Answer 1

The problem is that the test is async and mocha assumes that, if you don't return a promise from your test or specify a callback function, your test is synchronous (more info here).

So, add a callback function.

it("Root endpoint returns 200", function(done) {
  request(server)
    .get('/temp')
    .expect(200)
    .end(done);
});
