Testing is too hard.
Testing isn’t fun.
Testing is so sloow.
Testing sucks!

Unit Tests Integration Tests System Tests
Complexity
Functional
Test Code

You can’t fix what you can’t run.

You can’t fix what you can’t debug.

You can’t fix what you can’t test.

You can’t develop what you can’t test.

Not testing needs to be more painful
And time consuming than using testing.

What is touched
by testing?

An Innovative Testing Platform for the JVM

Guiding Principles
 Tests should be portable to any supported container
 Tests should be executable from IDE and build tool
 Should extend or integrate existing test frameworks
