48 | * This rule compares GUI event tasks (i.e. it is more concrete, than the |
---|
49 | * {@link EventTaskComparisonRule}). Two GUI event tasks are only equal if their event type and |
---|
50 | * target are equal. The returned equality is even more fine-grained for events whose type is |
---|
51 | * {@link TextInput} and {@link ValueSelection}. For text inputs, lexical equality is returned if |
---|
52 | * the same text is entered using the same key interactions. Syntactical equality is returned if |
---|
53 | * the same text is entered using different key interactions. Semantical equality is returned if |
---|
54 | * different text is entered, but into the same event target. Value selections are syntactically |
---|
55 | * equal, if the same value is selected. Otherwise they are semantically equal. |
