NAME
Test::BrewBuild - Perl/Berry brew unit testing automation, with remote tester dispatching capabilities.
DESCRIPTION
This module is the backend for the brewbuild script that is accompanied by this module.
For end-user use, see brewbuild. You can also read the documentation for the network dispatcher bbdispatch, the remote test listener bbtester, or browse through the Test::BrewBuild::Tutorial for network testing.
This module provides you the ability to perform your unit tests across all of your Perlbrew (Unix) or Berrybrew (Windows) Perl instances.
For Windows, you'll need to install Berrybrew, and for Unix, you'll need Perlbrew.
It allows you to remove and reinstall on each test run, install random versions of perl, or install specific versions.
All unit tests are run against all installed instances, unless specified otherwise.
SYNOPSIS
use Test::BrewBuild;
my $bb = Test::BrewBuild->new;
my @perls_available = $bb->perls_available;
my @perls_installed = $bb->perls_installed;
# remove all currently installed instances of perl, less the one you're
# using
$bb->instance_remove;
# install four new random versions of perl
$bb->instance_install(4);
# install two specific versions
$bb->instance_install(['5.10.1', '5.20.3']);
# install all instances
$bb->instance_install(-1);
# find and test against all the current module's reverse CPAN dependencies
$bb->revdep;
# run the unit tests of the current module only
$bb->test;METHODS
new(%args)
Returns a new Test::BrewBuild object. See the documentation for the brewbuild script to understand what the arguments are and do.
Many of the options can be saved in a configuration file if you want to set them permanently, or override defaults. Options passed into the various methods will override those in the configuration file. See config file documentation.
brew_info
Returns in string form the full output of *brew available.
perls_available
Returns an array containing all perls available, whether already installed or not.
perls_installed
Returns an array of the names of all perls currently installed under your *brew setup.
instance_install
If an integer is sent in, we'll install that many random versions of perl. If the integer is -1, we'll install all available versions. You can also send in an array reference, where each element is a version of perl, and we'll install those instead.
You can send a second parameter, an integer for a time out. On each install, we'll bail if it takes longer than this time. Default is 300 seconds. If you're on a fast machine, you should probably lower this value.
On Windows, where you want to install specific perls, we'll default to installing 64-bit versions only, if a 64 bit perl is available for the version desired and you haven't added the _64/_32 suffix per berrybrew available.
Simply add the _32 suffix if you want to install it specifically. Note that if you're dispatching to Unix and Windows servers, the Unix systems will remove this invalid portion of the version prior to processing further.
instance_remove
Uninstalls all currently installed perls, less the one you are currently switched or used to.
test
Processes and returns the test results as a string scalar of the distribution located in the current working directory.
revdeps
Returns a list of the reverse dependencies (according to CPAN) that the module you're working on in the current working directory have.
revdep
Loops over all of the current module's reverse dependencies, and executes test() on each one at a time. This helps you confirm whether your new build won't break your downstream users' modules.
legacy
By default, we don't install perl versions less than v5.8.9. Pass in a true value to override this default.
options(\%args)
Takes a hash reference of the command-line argument list, and converts it into a hash of the translated Test::BrewBuild parameters along with their values.
Returns the converted hash for passing back into new().
If an invalid argument is included, we'll set $args{error} = 1;. It is up to the caller to look for and process an error handling routine.
config_file
Returns a string that contains the path/filename of the configuration file, if available.
plugin('Module::Name')
Fetches and installs a custom plugin which contains the code that perlbrew/berrybrew exec will execute. If not used or the module specified can't be located (or it contains errors), we fall back to the default bundled Test::BrewBuild::Plugin::DefaultExec (which is the canonical example for writing new plugins).
Note that you can send in a custom plugin *.pm filename to plugin as opposed to a module name if the module isn't installed. If the file isn't in the current working directory, send in the relative or full path.
is_win
Helper method, returns true if the current OS is Windows, false if not.
log
Returns an instance of the packages log object for creating child log objects.
tempdir
Sets up the object with a temporary directory used for test logs, that will be removed after the run.
workdir
Returns the brewbuild working directory.
setup
Prints out detailed information on setting up a testing environment, on Windows and Unix.
help
Displays the brewbuild command line usage information.
