kotest equivalent to usingElementComparatorIgnoringFields from assertJ

Question

assertJ allows you to check for element-wise list equality while ignoring user specified fields like so

assertThat(listOfObjects)
    .usingElementComparatorIgnoringFields("field1", "field2", ...)
    .containsExactly(object1, object2, ...)

I have not been able to find any equivalent function in kotest. Is there an equivalent?

Answer 1

There is no such assertion at collection level, though you can perform similar assertion at individual object using shouldBeEqualToIgnoringFields matcher.
