+Test that dune doesn't allow the "with-test" solver variable to be set by the
+user.

+Add a workspace that attempts to set the "with-test" variable:
+  $ cat >dune-workspace <<EOF
+  > (lang dune 3.8)
+  > (lock_dir
+  >  (path dune.lock)
+  >  (solver_env

+  5 |   (with-test false)))
+        ^^^^^^^^^^^^^^^^^
+  Error: Setting the "with-test" solver variable is not permitted as it would
+  conflict with dune's internal use of "with-test" while solving opam packages.
