# The subcommand used is 'show history' but it is implemented
# as a subclass of Lister and it formats the results as such.
# Both tests use regex to keep only lines starting with UUID[1].
# As every validation run has UUID assigned and the 'value' output format
# places it's octal form in the first column, it is possible to use it to
# match only records about validation runs, and remove the rest.
