I was looking at the spec and it mentions that "unittest" is a special 
method in classes.

Can you have more than one unittest method in a class?

Unittests are actually not methods inside classes, but more statement blocks that are executed when you compile & execute unittests. So, they work as if you provide a void main () {} in every file/class/whatever scope you put them in. And yes, IIRC, you can have multiple unittest blocks per file, too. Though, they are all executed then. You could workaround that with version() { } blocks.

Thanks.  Another quick question.  Is "assert" legal syntax outside of 
contacts and unit tests?  For instance, can I do this:

unittest {
     someMethod();
}

void someMethod() {
     assert 0 == 1
}

assert(0 == 1);, but otherwise yes. -- Lars Ivar Igesund blog at http://larsivi.net DSource & #D: larsivi Dancing the Tango

Yes. Asserts are always evaluated if you provided -debug to the compiler. Of course for asserts in unittests to work you also have to provider -unittest to the compiler.

asserts are active unless you give the -release flag, even without the -debug flag
