 was ich so sehe ...
 
 ✅ Slack-Notifikation: statt Parsing-mechanismus eines Strings --> JSON in der INI schreiben
+
 ✅ `--ini=<FILE>` bei relativem Pfad ist relativ zum Binary --> nicht ins eigene Verzeichnis wechseln
+
 ⬜ Dokumentation
+
 ⬜ Code aufräumen
 
 ## Tests schreiben
 
 ✅ Test auf gesetzte Metadaten
+
 ⬜ für alle Checks einen Test schreiben
 
     ⬜ ApacheProcesses
-    ✅ Cert
-    ✅ Diskfree
+    ✅ Cert --> Hostname bei Wildcard-Zertifikat wird nicht erkannt
+    ✅ Diskfree --> preg_replace hat den Integer Wert noch geholt
     ✅ Exec
-    ⬜ File --> "exists": false meldet bei Test einer nicht existierenden Datei fälschlicherweise einen Fehler
+    ✅ File --> "exists": false meldet bei Test einer nicht existierenden Datei fälschlicherweise einen Fehler
     ✅ Hello
     ✅ HttpContent
     ✅ Loadmeter
-    ⬜ MysqlConnect
-    ⬜ PdoConnect

+⬜ parent Option testen

+⬜ group testen
+
 ## Done
 
 ✅ PHP compiliert zum Binary
+
 ✅ Binary startet in einem fremden Verzichnis
+
 ✅ Binary startet auf einen Nicht-PHP-System
