... extends TestCase {
public void myMethodTest() {
assertEquals("foo", "bar");
}
}

def spam(foo=None):
if foo is not N...

How does password salt help against a rainbow table attack?
...random, this is very unlikely. I'll probably have things like "hello" and "foobar" and "qwerty" in my list of commonly-used, pre-hashed passwords (the rainbow table), but I'm not going to have things like "jX95psDZhello" or "LPgB0sdgxfoobar" or "dZVUABJtqwerty" pre-computed. That would make the rain...
