[develop 2.0] consider removing scala as test dependency

[fehguy]

The tests are much easier to write with scala + scalatest, but it may be friendlier to developers to remove that and move to a pure java test framework.

[adrianbk]

Have you guys considered spock? It's an awesome testing framework.

Will definitely take a look. I get dizzy just thinking about going back to pure junit assertions.

[webron]

Umm, definitely not junit. If anything TestNG. Spock is probably worth looking at.

[fehguy]

I'm not going to do this for M1, will push to M2 and reconsider then.

+1 for spock - a great tool for writing simple yet expressive tests

Spoc is nice, but it requires Groovy, which is also fine, but poses the same downside as scalatest requiring Scala.

I recently stumbled over assertj and started to use it in some of my projects. It makes writing very good assertions really easy. IMHO, using this makes a bigger difference than using TestNG of JUnit.

[webron]

Well, we decided to go with TestNG for now.

TestNG is great, and assertj augments it nicely :-)
