Non-deterministic test failure in cluster_algebra_quiver #22482
Description
When running sage -t -a -p 0 in the develop Docker container (off a current version of the develop branch) I'm getting:
sage -t /opt/sage/src/sage/combinat/cluster_algebra_quiver/mutation_class.py
[54 tests, 0.34 s]
sage -t /opt/sage/src/sage/combinat/cluster_algebra_quiver/mutation_type.py
[71 tests, 0.88 s]
sage -t /opt/sage/src/sage/combinat/cluster_algebra_quiver/quiver.py
**********************************************************************
File "/opt/sage/src/sage/combinat/cluster_algebra_quiver/quiver.py", line 880, in sage.combinat.cluster_algebra_quiver.quiver.ClusterQuiver.mutation_type
Failed example:
Q.mutation_type()
Expected:
['G', 2]
Got:
'undetermined finite mutation type'
**********************************************************************
1 item had failures:
1 of 37 in sage.combinat.cluster_algebra_quiver.quiver.ClusterQuiver.mutation_type
[272 tests, 1 failure, 5.57 s]
but only sometimes. Seems like maybe a test ordering issue.
