Subject: [PATCH] fixed playTests.sh for minGW

On Windows, the equivalent of `/dev/null` is `NUL`.
When tests are run under msys2/minGW,
the environment identifies itself as Windows,
hence the script uses `NUL` instead of `/dev/null`
but the environment will consider `NUL` to be a regular file name.
Consequently, `NUL` will be overwritten during tests,
triggering an error.

This patch uses flag `-f` to force such overwrite
passing the test.
