  • Aristotle commented on Test2/Test::Builder Update from the QAH
    The 'explicit opt-in' approach works only until people start porting existing extensions on CPAN, which a number of Test:: authors have expressed an interest in, and then users would see far, far weirder breakages than what we're currently doing is likely to cause

    Just so this statement is not left unchallenged, let me be on record that in verbatim form this argument is nonsense; although it may be meant as a shorthand summary of a longer argument which does make sense.

  • Aristotle commented on Test2/Test::Builder Update from the QAH
    For TCM to work with Test2, every single module you use to output tests must also use Test2.

    This, however, I will call unqualified nonsense. Let me demonstrate to you why:

    1. Test::More will not be changing at all. Yet it will be able to coöperate with Test2-based modules just fine, by using a Test::Builder whose guts have been swapped for a Test2 wrapper.
    2. If it were true, that would mean that Test2 could not be released as part of Test::Builder without a simultaneous re-release every single test module on CPAN, ported to Test2. Otherwise CPAN …

    Aristotle said:

    Thus the claim that Test modules would have to be written specifically against Test2, in order to be able to work with other Test2-based modules, is simply factually incorrect.

    That wasn't what I was trying to claim. Maybe I don't understand what you and Leon wanted to happen.

    My point was simply that Test2-using tools will not cooperate with code that uses the existing pre-Test2 Test::Builder. Of course, if Test::Builder is using Test2 under the hood, then tools using Test::Builder do not also have to change (but AFAICT no one is say…

    Yes, sorry, I’ll be publishing a long-form, detailed version of the proposal very soon. I’ve realised the proposal is (either largely or entirely) non-understood – the abridged version I presented on the fly at that table was insufficient. (I had hoped but failed to have it out there sufficiently early before the QAH that people could digest it in detail.)

    My point was simply that Test2-using tools will not cooperate with code that uses the existing pre-Test2 Test::Builder.
  • Chad 'Exodist' Granum commented on Test2/Test::Builder Update from the QAH

    One of the initial options discussed as early as last year was this:

    Test2 and Test::Builder remain separate. Tools pick one a build with it. To use both together you load a shim such as Test2::Legacy, which replaces Test::Builder with the alternative guts.

    This was the alternative being discussed in the Test2 meeting on day 1 of the 2016 hackathon. We decided it was not the right plan. My main reason for opposing this plan is that nothing stops people from updating old modules to use Test2, and also auto-loading the shim to insure they do not break things that depend on them…
