I have heard/read writing common pre-conditions for a large number of test cases is a bad thing, since this dependency may cause large number of test cases to fail if something changes . What are your thoughts on it ?

If this is so , then what exactly is the purpose of setUp() method in Junit that runs before each test case ? If the same code inside setUp() runs before each test case , why cant it run only once before running all the test cases together ?

I'm working with a new team that has historically not done ANY unit testing. My goal is for the team to eventually employ TDD (Test Driven Development) as their natural process.
