With these basic tests, it's often a good idea to add --strict-whitespace and --match-full-lines to show that the formatting is as desired.

The previous version of this test had non zero values for the fields. I think it's important we do the same, because a 0 value could indicate an unset value in the tool code, rather than a value that has been read.

There should probably be a special case for 0 for some fields, where 0 has a special meaning (I'm looking at the TimeStamp specifically).

Set non-zero values for all fields (except for the aux file header which is not yet supported).
