Ant Builds, aber alle Junit-Tests schlagen fehl

Ich bin neu in der Verwendung von Ameise und Junit. Ich habe folgendes Problem. Meine ant build.xml wird erfolgreich erstellt, aber während der Ausführung der Junit-Tests wird die folgende Meldung angezeigt.

[echo] Running JUnit tests....
[mkdir] Created dir: /Users/george_ashiotis/Desktop/Coursework files-20180731/commons-validator-1.4.0/target/test-result

Hinweis: Dies geschieht für alle meine Testdateien.

Dies ist meine build.xml-Datei
