Another instance of the NoSuchMethodError for the JUnit & Hamcrest combination. Offending code:
NoSuchMethodError
assertThat(dirReader.document(0).getFields()
If you are using Eclipse: For me, in eclipse-> project properties->Java build Path moving mockito-all-1.9.5.jar to the bottom of the 'Order and Export' list did the trick. Just above that I have junit-4.11.jar and above that hamcrest-core-1.3.jar
