Regression Tests

There are currently 26 tests which are run as part of every PR. The CI tests use cmake and are based on the version of AMReX in the ERF submodule.

In addition there are nightly tests that use GNUMake and use the current development branch of AMReX.

Results from the nightly CPU tests can be found here: CPU tests

Results from the nightly GPU tests can be found here: GPU tests
