JUnit confusion: use 'extends TestCase' or '@Test'?
...
The distinction is rather easy:

Unit testing code with a file system dependency
...othing wrong with this, it's just a question of whether you call it a unit test or an integration test. You just have to make sure that if you do interact with the file system, there are no unintended side effects. Specifically, make sure that you clean up after youself -- delete any temporary fil...

Using arrays or std::vectors in C++, what's the performance gap?
...cies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%".
