Review comment:
1. factor out into a new method and use wherever the same test is made
1. use assertThat(fileNames).hasSize(0) and assertJ will report the full
fileNames contents

Review comment:
should this be a failure?
And it's also replicated in a lot of places. Can you pull it into its own
method

Review comment:
Can we move this to LambdaTestUtils.intercept()...it raises better
exceptions on failures, including the result of fsItr.next().toString() in the
message
