Presentation: Designing for Testability

Bookmarks

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.

Watch Designing for Testability (53 minutes).

    TDD leads to testable code by thinking tests first. That way you dont mess up code with static couplings, variables etc but Cedric instead talks against TDD and recommends write code first and and then change it to be testable when you start writing your test.

    I find TESTNG useful for functional testing tools like tests in the ui level using tools like Selenium where Dependent methods might be useful. But I dont think it is a very bad practice to have dependent tests in isolated focused unit tests.

    Yes, something wrong? I can't see it.
