Presentation: Designing for Testability
In this presentation from QCon San Francisco 2007, Cedric Beust and Alexandru Popescu discuss interesting features of TestNG such as grouping of tests, data providers for tests and dependency handling in tests, tips for designing easily testable code such as eliminating statics, extreme encapsulation and TDD, the importance of functional versus unit testing, and migrating from JUnit to TestNG.

Test Driven Development or Test Driven Requirements?
Where does one start when practicing test driven development? With the requirements or with the design? Or, put another way, top-down or bottom-up? When one starts to write a test first, without any code, what does that test represent? Both approaches are practiced in the Agile community, but there is little consensus on which provides more value.

What Makes a Tool Agile?
Individuals and interactions over processes and tools is the very first of the values of the Agile Manifesto. Tools, however, seem to be a big part of development on most Agile teams. When does a tool help and when does it hinder (Agile) software development?

ObjectMother - a Forgotten Testing Tool
One of the earliest techniques for writing tests using TDD did not use mocks and stubs, but used the actual business objects instead. By creating a set of factories that instantiated, composed, and executed methods on business objects, real objects, in a non-initial-state of their lifecycle, could be created for testing purposes. The name coined for this pattern was ObjectMother.

Presentation: System Integration Testing with Spring
Spring provides a holistic solution that makes your application's use cases and subsystems easier to test. The emphasis is on testing outside a JEE server or container, thus greatly improving productivity. In this presentation, Spring Creator Rod Johnson discusses integration testing and the support that Spring provides for it.

Testing and Quality Control the only Certification Needed?
A new certification for software developers that is neither about in depth knowledge of programming languages, nor any modelling and design techniques, was suggested by Reginald Braithwaite. Only one subject would be on the examination list - "Testing and quality control". Safety has to be the prerequisite to any software development job. For the rest marketplace will decide.

100% Test Coverage?
How much testing is enough? The answer varies depending on whom you ask. On one end of the spectrum, some say you should strive to achieve 100% test coverage. Others say it doesn't matter, that you should just rely on the quality of the tests, and that measuring test coverage does not tell you anything about the quality of the tests and the code being tested.
