title: AssertJ on list of Optionals
body: <p>I have a List of Optionals, like <code>List&lt;Optional&lt;String&gt;&gt; optionals</code> and I like to use <code>assertj</code> on it to assert several things.</p>
  
  <p>But I fail to do this properly - I only find examples on a single Optional.</p>
  
  <p>Of course I can do all checks by myself like</p>
  
  <p><code>Assertions.assertThat(s).allMatch(s1 -&gt; s1.isPresent() &amp;&amp; s1.get().equals("foo"));</code></p>
  
  <p>and chain those, but I still have the feeling, that there is a more smart way via the api.</p>
  
  <p>Do I miss something here or is there no support for <code>List&lt;Optional&lt;T&gt;&gt;</code>in assertj ?</p>
