NAME

brewbuild - Automate module and reverse-dependency testing, on Windows and Unix

SYNOPSIS

You must be in the root directory of the distribution you want to test.

Run all unit tests against all installed instances with no other action. Upon a FAIL, a log file will be generated in the current working directory named bblog/version.bblog

    brewbuild

    # output

    5.8.9 :: PASS
    5.20.3 :: FAIL
    5.22.1 :: PASS

Run tests on the local working copy of the current module, then run all tests of all reverse dependencies of this module (as reported by CPAN), to ensure the down river modules will work with your new build. In this case, FAILs are stored in bblog/revdep-module-name.version.bblog

    brewbuild -R

    # output, in my Mock::Sub repo directory

    reverse dependencies: Test-BrewBuild, File-Edit-Portable,
      Devel-Examine-Subs, Devel-Trace-Subs

    Test::BrewBuild
    5.18.4 :: FAIL
    5.22.1 :: PASS

    File::Edit::Portable
    5.18.4 :: PASS
    5.22.1 :: PASS

    Devel::Examine::Subs
    5.18.4 :: PASS
    5.22.1 :: PASS

    Devel::Trace::Subs
    5.18.4 :: PASS
    5.22.1 :: PASS

DESCRIPTION

This brewbuild script installed by the Test::Brewbuild module allows you to perform your unit tests seamlessly across all of your Perlbrew (Unix) or Berrybrew (Windows) Perl instances, as well as test all of your down-river CPAN modules that rely on your module against the locally updated version, with support for ExtUtils::MakeMaker, Module::Build and Dist::Zilla distributions.

For Windows, you'll need to install Berrybrew (see "SEE ALSO" for details). For Unix, you'll need Perlbrew.

It allows you to remove and reinstall on each test run, install random versions of perl and install specific versions.

All unit tests are run against all installed perl instances, unless otherwise specified.

USAGE

-o, --on

Perl version number to run against (can be supplied multiple times). Can not be used on Windows at this time.

-R, --revdep

Run tests, install, then run tests on all CPAN reverse dependency modules.

-d, --debug

0-7, sets logging verbosity, default is 0.

-n, --new

How many random versions of perl to install (-1 to install all).

-r, --remove

Remove all installed perls (less the currently used one).

-i, --install

Number portion of an available perl version according to *brew available. Multiple versions can be sent in at once.

-N, --notest

Do not run tests. Allows you to --remove and --install without testing.

-S, --save

By default, we save logs of FAIL result logs into the bblog directory. With this flag, we'll save both the FAIL logs along with all the PASS logs as well.

-l, --legacy

Operate on perls less than 5.8.x. The default plugins won't work with this flag set if a lower version is installed.

-p, --plugin

Optional module name of the exec command plugin to use. You can also specify a file name if the module is not installed.

-a, --args

List of args to pass into the plugin (one arg per loop).

-T, --selftest

Test::BrewBuild development testing only. Prevents recursive test loops.

-s, --setup

Display test platform setup instructions.

-h, --help

Print out the command line usage information.

TEST PLATFORM CONFIGURATION

Test::BrewBuild test platform configuration guide

UNIX

Install perlbrew and related requirements:

    cpanm App::perlbrew
    perlbrew install-patchperl
    perlbrew install-cpanm

Install and switch to your base perl instance, and install Test::BrewBuild:

    perlbrew install 5.22.1
    perlbrew switch 5.22.1
    cpanm Test::BrewBuild

WINDOWS

Note that the key is that your %PATH% must be free and clear of anything Perl. That means that if you're using an existing box with Strawberry or ActiveState installed, you *must* remove all traces of them in the PATH environment variable for ``brewbuild'' to work correctly.

Easiest way to guarantee a working environment is using a clean-slate Windows server with nothing on it. For a Windows test platform, I mainly used an Amazon AWS t2.small server.

Download/install git for Windows:

    https://git-scm.com/download/win

Create a repository directory, and enter it:

    mkdir c:\repos
    cd c:\repos

Clone and configure berrybrew

    git clone https://github.com/dnmfarrell/berrybrew
    cd berrybrew
    bin\berrybrew.exe config (type 'y' when asked to install in PATH)

Note: I have forked and hacked berrybrew with a few changes which makes it play nicer with brewbuild (and adds the --with feature for exec) if you're interested. My changes haven't been merged yet, so you can fetch it from here.

Close the current CMD window and open a new one to update env vars

Check available perls, and install one that'll become your core base install

    berrybrew available
    berrybrew install 5.22.1_64
    berrybrew switch 5.22.1_64
    close CMD window, and open new one

Make sure it took

    perl -v

Install Test::BrewBuild

    cpanm Test::BrewBuild
