 Warum wird meine Ausnahme nicht von junits „assetThrows()“ abgefangen?

Post by Guest »

Ich habe versucht, mit einem JavaFX ChangeListener eine Ausnahme auszulösen, wenn eine JavaFX-Eigenschaft durch eine Bindung auf einen ungültigen Wert gesetzt wird. Das ist vielleicht nicht der richtige Weg, um mein Ziel zu erreichen, aber jetzt bin ich neugierig: Ich konnte dieses Verhalten mit Junit5 nicht testen. Unten finden Sie ein minimales Arbeitsbeispiel meines Versuchs.
class PropertyValueLimiterTest {

@Test
void bind_invalidValue_MWE(){
Set allowedValues = Set.of("foo", "bar");
Property property = new SimpleObjectProperty("foo");
ChangeListener listener = (observable, oldValue, newValue) -> {
if(! allowedValues.contains(newValue)){
throw new IllegalArgumentException();
}
};
property.addListener(listener);
Assertions.assertThrows(IllegalArgumentException.class,
() -> property.setValue("invalid"));
}
}

Wenn ich diesen Code ausführe, passieren zwei Dinge:
  • Der Test schlägt fehl, weil die erwartete Ausnahme nicht ausgelöst wird;
    Junit5 teilt mir mit, dass eine Ausnahme ausgelöst wurde, die der von mir erwarteten entspricht: Ausnahme im Thread „Test worker“ java.lang.IllegalArgumentException (vollständiger Stacktrace unten).
Bearbeiten:
Bei #2 weiß ich, dass meine erwartete Ausnahme ausgelöst wurde. Warum schlägt der Test also fehl?
Vollständiger Stack-Trace (wobei ich die Zeilennummer der drei Zeilen aus meiner Datei bearbeitet habe, um die richtige Zeile anzuzeigen, die sie in dem Beispiel auslöst, in dem ich die Importe weggelassen habe):
