* brute force testing of format function

* idea for testing formatted output using git-testtools arguments

* fix formatting

* updates to use external file w/ regex in it

* trying standard path separator to see if windows ci passes

* updates to regex that make it easier to read

* test coverage of serializer using json

* fix formatting

* better assert logic for bare repo and pretty assert to debug CI failure in json

* fixing git version in json serializarion

* obtains 100% code coverage by manipulating git repo and files parsed

* more code coverage, trying to get those last few lines

* making use of snapshot name in testing

* changing verification to string based test

* switching to using inst snapshots

* adding snap file needed for previous commit

* refactor default into Config object to allow Default construction

* better naming on function

* removing snap file from ignore

* using object serialization in test
