+# This test makes sure workspace mode's handling of the module graph
+# is compatible with module pruning. The graph we load from either of
+# the workspace modules should be the same, even if their graphs
+# don't overlap.
+#
+# This is the module graph in the test:
+#
+#  example.com/a -> example.com/b v1.0.0 -> example.com/q v1.1.0
+#  example.com/p -> example.com/q v1.0.0
+#
+# If we didn't load the whole graph and didn't load the dependencies of b
+# when loading p, we would end up loading q v1.0.0, rather than v1.1.0,
+# which is selected by MVS.
+# TODO(#48331): We currently load the wrong version of q. Fix this.
+
+go list -m -f '{{.Version}}' example.com/q
+stdout '^v1.0.0$' # TODO(#48331): This should be 1.1.0. Fix this.
