Prettify assert actual and expected values

[zeegin]

When unit tests raise assert error we shuld pass actual and expected values.
But this values can be non primitive.
It include some references or collections.
To better marge-view in JUnit panel is shuld be full printed values, including types, collection items or structure properties.
Open question is how prettify nested collections? Maybe we must convert it to json.

Maybe like in java?

I found only one example

But I don't understand how this properties contains in junit json.
