+dir /b Makefile test_builtins.cmd
+dir /b Makefile
+dir /b test_builtins.cmd
+dir /b "Makefile"
+dir /b "test_builtins.cmd"
+"dir /b Makefile"
+"dir /b test_builtins.cmd"

You can't assume that these files are present when running the test. If you need additional files for test, you have to create them in runtime. In this particular case it looks like you could choose other builtin command for test that doesn't require any additional file.
