Yes... I've heard about Spock ;-) and most likely dozens of other testing frameworks which were created after JUnit started to exist. JUnit is old, it's sometimes a bit grumpy, nevertheless it is stil very concise and lightweight library. It is enough to spend 10 minutes with JUnit documentation to understand the basic elements of test, how to write an assertion and how to launch your first test. In a day to day job there are several other JUnit features which might be very handy, there are also a few curosities worth to mention. In this presentation I will try to cover most of them including: parameterized tests, theories (org.junit.experimental.theories), rules (@Rule) and common matchers. As was already said JUnit is not a newbie in a testing framework world, over the years several additional libraries were added, I will show you a few interesting once, including randomized testing, benchmarking and REST interactions testing.
This presentation was developed with the support of Poznań JUG, Tricity JUG and Szczecin JUG who were hosting this lecture in the past. Discussion which we had during and after the meetings was a great aid and influenced heavily current content of this presentation.
