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

Another option available now is to use the Cirneco extension for Hamcrest. It has hasSameKeySet() (as well as other matchers for Guava "collections"). According to your example, it will be:

assertThat(affA, hasSameKeySet(affB));

You can use the following dependency for a JDK7-based project:

  it.ozimov
  java7-hamcrest-matchers
  0.7.0

or the following if you are using JDK8 or superior:

  it.ozimov
  java8-hamcrest-matchers
  0.7.0
