"xtest" target for Makefile

[karenetheridge]

'make xtest' should be available through standard use of Makefile.PL.

IMO it's sufficient to just have it target "xt/*", but if we wanted to get fancy we could glob-expand that and then:

• trim xt/author/ if not $ENV{AUTHOR_TESTING}
• trim xt/release/ if not $ENV{RELEASE_TESTING}
• trim xt/smoke/ if not $ENV{AUTOMATED_TESTING}

I would do that subtly different, but that's mostly bike-shedding:

• run xt/*.t && xt/author/ if $ENV{AUTHOR_TESTING}
• run xt/release/ if $ENV{RELEASE_TESTING}
• run xt/smoke/ if $ENV{AUTOMATED_TESTING}

A far more interesting question: should make xtest also run t/. To me, it'd be fairly useless without that.

Actually, given the semantics I just proposed, a separate xtest target wouldn't be necessary. A make test that takes those variables into account would be enough.

Not that either behavior is particularly trivial to implement in a portable makefile :-/

I think 'make xtest' should always run xt/* (minus the special sub-directories) regardless of the environment, just as Dist::Zilla::Plugin::RunExtraTests does... just as mauve is a good colour for that bikeshed. :)
