My first comment would be why are you testing GridapPETSc.jl, instead of GridapSolvers.jl?

Otherwise, the error seems to be related to MPI.

• Where are you running your tests? Are you using custom binaries, or artifacts?
• When using MPI you have to build your project, not only instantiate. Most weird errors go away after building, which is crucial to link all the binaries together.

You are right, I did start by testing GridapSolvers, but the errors below seemed to implicate GridapPETSc. I may be wrong, of course.
This is from the failed test of GridapSolvers:

It's an MPI issue, I think. The serial tests are running fine on both cases, but it fails to load the environment when doing the MPI tests.
Try building the packages first, then run the tests. Instantiating is not enough. I.e

using Pkg
Pkg.build()

If you follow the README.md, everything is there.

[PetrKryslUCSD]

I did what the README suggested. Activ/inst + build.

I think MPI.jl might have disabled some mpiexec flags we were using (namely --allow-run-as-root), I've pushed a couple changes to main.

Could you please try this:

using Pkg
Pkg.add(;name="GridapSolvers",rev="main");
Pkg.build()

then exit and re-start julia, which allows the links created by build to take effect. I think this was what was causing the issue on your end. If you don't restart, the changes don't take effect. Once this is done, try testing it.

I just tested this on our linux cluster, and it seems to run.

[PetrKryslUCSD]

Fantastic, all tests pass.

[JordiManyer]

Great, I'll do a new minor release and modify our README to make all of this more clear.
