After installation, error in test

16 failed and 3946 passed.

how to pass the failed tests?

These failing tests are related to k3d (a way to display 3d visualisations).

As we don't know how you installed Ubermag and on which operating system, it is hard to say what the problem is.

However, as long as you are happy not to use k3d visualisations (which are not essential), you are good to use ubermag.
