### Question:
TypeSimplifier { static String packageNameOf(TypeElement type) { return MoreElements.getPackage(type).getQualifiedName().toString(); } TypeSimplifier(
      Elements elementUtils,
      Types typeUtils,
      String packageName,
      Set<TypeMirror> types,
      TypeMirror base);   }### Answer:
@Test public void testPackageNameOfString() { assertThat(TypeSimplifier.packageNameOf(typeElementOf(java.lang.String.class))) .isEqualTo("java.lang"); }
@Test public void testPackageNameOfMapEntry() { assertThat(TypeSimplifier.packageNameOf(typeElementOf(java.util.Map.Entry.class))) .isEqualTo("java.util"); }
