test.cb does not timeout

[gajus]

Description

I am using test.cb callback to define an asynchronous test. My test is failing (the expected callback is not called).

Current behaviour

This leaves the entire test suite hanging indefinitely.

Expected behaviour

Expect the test to fail after some X time.

Test Source

test.cb.only('togglePushdown', (t) => {
  console.log('A 0');

  const div = document.createElement('div');

  console.log('A 1');

  div.id = 'pushdown';

  document.body.appendChild(div);

  console.log('A 2');

  const origAnimate = minidom.animate;

  minidom.animate = (...args) => {
    console.log('A 5');

    t.deepEqual(args[1], {
      height: 250
    });

    minidom.animate = origAnimate;

    t.end();
  };

  console.log('A 3');

  AdsManager.togglePushdown();

  console.log('A 4');
});

This produces:

A 0
A 1
A 2
A 3
A 4

Error Message & Stack Trace

None. The test is just hanging.

Config

Copy the relevant section from package.json:

{
  "ava": {
    "require": [
      "babel-register"
    ],
    "babel": "inherit"
  }
}

Command-Line Arguments

Copy your npm build scripts or the ava command used:

ava --verbose --serial --fail-fast --watch ./test/AdsManager.js

Environment

Tell us which operating system you are using, as well as which versions of Node.js, npm, and AVA. Run the following to get it quickly:

$ node -e "var os=require('os');console.log('Node.js ' + process.version + '\n' + os.platform() + ' ' + os.release())"
$ ava --version
$ npm --version
Node.js v7.1.0
darwin 16.1.0
0.17.0
4.0.2

Side note

It would be a useful addition if the DEBUG=* logged which tests it is entering/ leaving to help debug issues such as this one. Now if the test is set to only I am not getting any output unless there is a console.log in the script itself.

$ DEBUG=* ava --verbose --serial --fail-fast --watch ./test/AdsManager.js
ava ipc stats:
{ testCount: 1, hasExclusive: true, file: 'test/AdsManager.js' } +0ms
A 0
A 1
A 2
A 3
A 4

[sindresorhus]

You need to use the --timeout CLI flag.

[gajus]

Right. I apologize. I was under impression that there is a default global timeout.

[sindresorhus]

@gajus We considered having a global default, but we realized there's no good default that works for everyone. Instead, we plan to show when we think a test is hanging: #583 (Help welcome btw)

[QuotableWater7]

@sindresorhus I'd be happy to help look into a solution for #583. To speed along the process, do you know which file(s) I should be taking a look at?
