Stop requiring only one assertion per unit test: Multiple assertions are fine

I'm not aware of any related to testing, but perhaps you could use something like this in tandem with some tests to pull it off?

Yup, it's why I built `just-tap` [1] which trys to minimise as much magic that a lot of these frameworks try to "help" you with.

This can be improved, it'd be worth Googling for a better solution than what you have.

https://github.com/skyscreamer/JSONassert seems decent.

but it can be done from scratch in a few hours (I'd recommend this if you have 'standardized' fields which you may want to ignore):

1) Move to a matcher library for assertions (Hamcrest is decent), and abstract `toJSON` into the a matcher, rather on the input.

This would change the assertion from:

`assertEquals(toJson(someObject), giantJsonBlobFromADifferentFile)`

to:

`assertThat(someObject, jsonEqual(giantJsonBlobFromADifferentFile))`

The difference here is subtle: it allows `jsonEqual` to control the formatting of the test failure output, so on a failure you can:

* convert both of the strings back to JSON

* perform a diff, and provide the diff in the test output.
