Hi all,

order to test our rx handlers. Does exist such component in

We don't have a USRP2 simulator, but it would certainly be a good thing
to have.

I have seen you use as unit test framework CppUnit, lately
I have switched from CppUnit to gtest, is not hard to convert
the old CppUnit tests, I converted myself around 250 test
cases in a single day, having at the end more features like:
disable some tests, run a single one, repeat some tests
multiple time and other features you can read about it on
gtest documentation.

We'll have to take a look at gtest. Is cppunit no longer developed?

The last release is early 2008, but I see checkin's in their svn in the past month.


Running our application under valgrind (3.5.0) no usrp2 is found,
anyone has an idea why?
