You should compare the test output without using a temporary file and without
hashing, e.g.,
```
assertTrue(Files.asByteSource(fileToUpload).contentEquals(ByteSources.asByteSource(read.getPayload())));
```
This will read better when you convert `fileToUpload` into a pure `ByteSource`
instead of a `File`. Note that assertj has an `assertEquals(InputStream,
InputStream)` if we bring in that dependency.
