+Given a working directory cram test:
+  $ mkdir sometest.t
+  $ cat >sometest.t/run.t <<EOF
+  >   $ echo "foobar"
+  >   foobar
+  > EOF
+
+  $ dune build @sometest
+
+We turn it into a single-file test:
+  $ mv sometest.t sometest.t.bak
+  $ mv sometest.t.bak/run.t sometest.t
+  $ rm -r sometest.t.bak
+
+Dune detects the change:
+  $ dune build @sometest
+
+The other way. Turn the file test into a directory test:
+
+  $ mv sometest.t sometest.t.bak
+  $ mkdir sometest.t
+  $ mv sometest.t.bak sometest.t/run.t
+
+And this works:
+  $ dune build @sometest
