Agenda
Why I like Spock?
Less know, but cool Spock features
New and noteworthy in Spock 1.0
Spock tricks

View Slide

Why idea for this presentation?
JUnit/TestNG + Mockito + AssertJ work...
... but Spock brings testing to another level
Integrates seamlessly with production Java code
Since version 1.0 provides even more useful features

Encourage more people to using Spock
In even more effective way

Why I like Spock?
Consist and readable test code
Tests as specification by default
All Groovy magic available to help
Embedded mocking framework
Although Mockito can be used if preferred
Highly extensible
Compatible with tools supporting JUnit
