I've used both, but I have to agree with Justin Standard that you shouldn't really consider rewriting your existing tests to any new format. Regardless of the decision, it is pretty trivial to run both. TestNG strives to be much more configurable than JUnit, but in the end they both work equally well.

You don't mention what the target project is; having a process per-tab does not necessarily mean more "robust" code at all. You should aim to write solid code with tests regardless of portability - just read about writing good C++ code :)

The output of the explain tells you how long each step has taken. The first thing is to find the steps that have taken a long time and understand what they mean. Things like a sequential scan tell you that you need better indexes - it is mostly a matter of research into your particular database and experience. |
From the dinosaur OS book ("Applied operating System Concepts"):
**Time sharing,** or **multitasking**, is a logical extension of multiprogramming. The CPU executes multiple jobs by switching among them, but the switches occur so frequently that the users can interact with each program while it is running. |
One "Oh no, that's not right" is often in the form of a **table scan**. Table scans don't utilize any special indexes and can contribute to purging of every useful in memory caches. In postgreSQL, for example, you will find it looks like this.

This depends on what you mean by 'good' and 'bad'.

They can be useful for unit testing so that when writing tests you know what to expect the function to throw when it fails, but there is no enforcement surrounding them in the compiler.
