Multithreaded tests? The Conductor class?

[KajMagnus]

Hi,

Is there any Specs functionality for testing thread safe objects?

In Specs2 ?

***

Would you recommend that I use ScalaTest instead of Specs to test
thread safety?

***

A while ago there was a class
svn/trunk/src/main/scala/org/specs/matcher/concurrent/
Conductor.scala
in the SVN repo.

but it was removed (in SVN r1155). Do you know why?

SVN r1155 log message:
"removed the concurrent package" (okay, hmm, but why? :-) )

( http://code.google.com/p/specs/source/detail?r=1155 )


Kind regards, Magnus

Hi Magnus,

That code was originally provided by Josh Cough as a Scala port from the Java version. I tried to integrate it with specs at the time but that didn't work (specs design was not adapted to multi-threading). Bill Venners put in extra effort to make this work for ScalaTest and you can definitely use it with ScalaTest.

That being said, if you find this really useful for multi-thread testing and if I get the permission from Josh and Bill, I can try to integrate it to specs2.

Before that, maybe you could elaborate a bit on the kind of test you'd like to specify? Is the Conductor way of doing things exactly what you want?

Eric.

Hi Eric,

Thank you very much for your reply :-)

I don't know, actually.

I intended to do some load testing of my Data Access Object,
and thought perhaps there was some multithreading module in Specs I could use,
and started looking for some multi-thread testing module.
But I don't know how the multi-thread tests could work.
(I'm fairly new to Specs... and somewhat new to Scala too :-) )

(Right now I might as well create 100 threads and have them attack the DAO.
Later on, I will probably do more elaborate multithreaded testing of my app.)

Kind regards, Magnus

Don't hesitate to come back with anything that you'd find interesting for a specs2 addition,

Thanks,

Eric.
