console.log inside QUnit.done does not work in terminal

[lolmaus]

Tell us about your runtime:

• QUnit version: 2.4.1
• What environment are you running QUnit in? (e.g., browser, Node): browser (Chrome headless)
• How are you running QUnit? (e.g., script, testem, Grunt): Ember CLI 2.18, which is using Testem

What are you trying to do?

Code that reproduces the problem:

QUnit.done(() => console.log("foo"));

This code is executed in the browser environment. I have no access to Node features from there.

What did you expect to happen?

The log message is visible when I run tests with the terminal output (via ember test --serve, which is using Chrome headless).

What actually happened?

The log message is only visible when I run tests in browser (ember test --serve). When I run tests in the terminal (ember test), the log message is not visible. It does not appear in the CI.

console.logs made during test execution do appear in the terminal. But my goal is to collect some stats about tests and spit them out after all tests complete.

This isn't an issue with QUnit but with the testing setup provided by Ember-CLI.

In particular, Testem requires you use an adapter to bridge the browser-node communication gap. By default it provides a QUnit adapter that sends the necessary reporting info for tests. You might need to extend that adapter or define your own as mentioned here.
