If the answer is "run the tests yourself", that's perfectly acceptable. But if, for example, you run them before merging to default/master (and therefore default/master can be considered "blessed") then maybe I don't need to bother.

For default/master I (and occasionally some other users) also run 
Nightly builds:
http://manao.inria.fr/CDash/index.php?project=Eigen (also for C++03 and 
C++11 only. Eventually, I'm planning to make running with newer 
standards more easy. See http://eigen.tuxfamily.org/bz/show_bug.cgi?id=1655)

Gaël also runs builds which are triggered by any incoming commit (I 
think also with C++14 or C++17, but I'm not sure).
"Usually" any changes are tested before they are pushed, but accidents 
can happen, of course. And naturally, there can also be errors which are 
not (yet) covered by any unit test.

On the other hand, nothing (implicitly) happens due to failed tests (in 
fact some failing tests are known issues ...), unless someone looks at 
the dashboard and takes care of them (I usually do, but there is no 
guarantee for that).

If you want to be sure, pull some version, run the test-suite yourself 
and only update occasionally (e.g., if you need a newly added feature or 
bug-fix). And please report any issues you get!


Cheers,
Christoph
