Hello,

can someone give me a complete example please how to do 
unittests? I tried this with the example from german wikipedia, 
but the flag -unittest didn't make any difference.

Example file with loads of unittests: 
https://github.com/rikkimax/alphaPhobos/blob/master/source/std/experimental/uri.d

If you were to compile it e.g. dmd uri.d it won't be much use (unittest 
wise). You will need to dmd -unittest uri.d to compile them in. Don't 
forget to do the same for your main function. When you run the final 
executable the tests will execute before your main function does.

can't I do unittest in the main?

D unit tests are like a stack of free functions. You put them 
separatly.


when there's a main: dmd -unittest a.d
--
module a;
void main(){}

unittest{}
--


when there is no main: (like std.uri): dmd -main -unittest a.d
--
module a;
unittest{}
--

the -main switch adds a dummy main function so that the output 
can be executed.

But most of the time you'll think that nothing happens because 
the tests succeed...

So do I understand it right that it stops after the first failed 
test? Is it possible to continue and get a list of all failed 
tests?

Once a unittest block within a module has a failure in it, then no more
unittest blocks within that module are run. However, unittest blocks in
other modules will still be run. So, if you have failures across multiple
modules, then you'll see multiple failures, but if it's just one module,
then you'll only see the first one, because any further tests within the
module won't even have been run.
