+# Don't create a ctx for every test.
+# Problem is, that if for every test we create a workflow that contains just one standard
+# lifecycle operation, then by the time we try to run the second test, the workflow failes since
+# the execution tries to go from 'terminated' to 'pending'.
+# And if we write a workflow that contains all the lifecycle operations, then first we need to
+# change the api of `mock.models.create_interface`, which a lot of other tests use, and second how
+# do we check all the state transition during the workflow execution in a convenient way.
