[JAVA] Einschlussbeziehungen der Testliste zu AssertJ

Aufführen

Listen

Das Ergebnis ist der erwartete Wert ...	`assertThat(actual).xxx(expected)`
Gleich wie (in keiner bestimmten Reihenfolge)	`containsOnlyElementsOf` `containsExactlyInAnyOrderElementsOf`
Einschließlich aller	`containsAll`
Alles enthalten in	`isSubsetOf`
Einschließlich sogar einer	`containsAnyElementsOf`
Enthält keine	`doesNotContainAnyElementsOf`

Listen und Elemente

Das Ergebnis ist der erwartete Wert ...	`assertThat(actual).xxx(expected)`
einschließen	`isIn`
Nicht enthalten in	`isNotIn`
Einschließlich (alle)	`contains`
Beinhaltet nicht (niemand)	`doesNotContain`

Beispielcode

Alle letzten Behauptungen schlagen fehl.
