Map equality using Hamcrest

Question

I\'d like to use hamcrest to assert that two maps are equal, i.e. they have the same set of keys pointing to the same values.

My current best guess is:

a         


        

Answer 1

Hamcrest now has a Matcher for size collection.

org.hamcrest.collection.IsCollectionWithSize

Answer 2

A quite simple way is to use a utility method from Guava's com.google.common.collect.Maps class.

assertThat(Maps.difference(map1,map2).areEqual(),is(true));
