Hi Francis,
Thanks for choosing to try Firedrake. Those three tests failing are a known
issue. It's a very subtle bug that we have yet to fully hunt down. It's
actually some tests interfering with each other. If you run the tests
independently (e.g. by running python
tests/regression/test_assembly_cache.py) then the tests should pass.
Since you only have those three test fails, your Firedrake install is
working correctly.
Regards,
David
