It fixes the impossibility that the
rules
andskip
options specified inspeccy.yaml
config file are used when these options are not override from command line.The
Commander.js
configuration has an empty array as a default/initial value forrules
andskip
. If you execute thelint
command from the command line without specifying those arguments, when the config is loaded those 'supplied' literal config values (empty arrays) overrides the ones defined in aspeccy.yaml
file (because they are notundefined
).There is a test validating the config hierarchy but, as the configuration passed to
init()
is handcrafted, it wasn't simulating the output ofCommander.js
read options.Now, a test simulating this case was added.
