    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.
