While working on https://github.com/js-reporters/js-reporters/tree/update-spec, I noticed that the test name property is called testName, I think it is not necessary to be called this way, if it is already attached to a test object, as also it was not in sync with the suite object who's name property is called name. I hope you agree.

EDIT: I am thinking to fix multiple things in this pr, that's why the questions below:

1. Should we add an Assertion class ?
2. What is the toJSON method about defined on the Suite prototype?

Changing to name makes sense. Can land this immediately.

As for toJSON, I can't remember. It was introduced here, which doesn't help: 1a54b8e#diff-0198054f2bb34911d00c2e884ea25e01R60

Let's try to the defineProperties call and see what happens.

It was introduced here

Yeah, it doesn't help so much, I see that there was also an Error class that was removed. So is a good idea to create an Assertion class ?

Please review @jzaefferer.
