Truth ignore field

For Truth, we decided not to provide reflection-based APIs, so there’s no built-in equivalent.

Our general approach to custom comparisons is Fuzzy Truth. In your case, that would look something like this (Java, untested):

Correspondence<CalendarEntity, CalendarEntity> ignoreId =
        (a, b) ->,
        "fields other than ID");

If you anticipate wanting this a lot (and you want to stick with Truth rather than AssertJ), then you could generalize the ignoreId code to work with arbitrary field names.

(Also: In this specific example, your CalendarEntity has only one field that you do want to compare. In that case, you can construct the Correspondence in a slightly simpler way: Correspondence.transforming(CalendarEntity::name, "name").)
