Added a simple test script

acme-copy-certs/tests/test.py

+#!/usr/bin/env python3
+
+import time
+import cert_updater
+import file_watcher
+
+if __name__ == "__main__":
+    u = cert_updater.CertUpdater('./acme.json', '.')
+
+    f = file_watcher.FileWatcher('./acme.json', u.update)
+
+    u.add('pica01-test.picasoft.net')
+
+    f.start()
+    
+    try:
+        while True:
+           time.sleep(1) 
+    except KeyboardInterrupt:
+        f.stop()
