Testing a Dancer2 app with locally installed modules

GertMT has asked for the wisdom of the Perl Monks concerning the following question:

Just decided to get more into testing (i've read it is almost guaranteed my code will improve..). I created a new Dancer2 app. The modules I use are installed locally via a cpanfile and a `carton install` command. Everything works though I cannot get the testing to work as I get warnings like:

Can't locate Dancer2/Plugin/Database.pm in @INC (you may need to insta
+ll the Dancer2::Plugin::Database module)
[download]

bin/app.psgi looks like:

#!/usr/bin/env perl

use strict;
use warnings;

use File::Basename;
use File::Spec;
use lib File::Spec->catdir( File::Basename::dirname( File::Spec->rel2a
+bs($0) ),
    '..', 'local/lib/perl5' );
use lib File::Spec->catdir( File::Basename::dirname( File::Spec->rel2a
+bs($0) ),
    '..', 'lib' );

use jwsDancer;

jwsDancer->to_app;
[download]

lib/jwsDancer.pm

package jwsDancer;
use Dancer2;
use Dancer2::Plugin::Database;
use Dancer2::FileUtils qw/path read_file_content/;

use Cwd qw(abs_path);
use lib dirname( dirname abs_path $0) . '/../../lib';

get '/' => sub {
    template 'index' => { 'title' => 'a web page' };

true;

For now I'm just trying to use the test that is generated by scaffolding a Dancer2 app via

prove -lv t/002_index_route.t

Can anyone give a hint what I should do to have the locally installed modules (in local/lib/perl5) work as well in the testing environment?

Why aren't you using boilerplate? hardcode `$ perldoc prove \|grep include -I Library paths to include.` [download]	[reply] [d/l]

Thank you Anonymous Monk! Apparently the code in lib/jwsDancer.pm contained an error. With the script as you suggested in bin/myprove.pl I got it to work changing the path slightly (erroneously it went up one directory too far). `use FindBin; chdir "$FindBin::Bin/.."; # jwsDancer/bin/.. system $^X, '-S', 'prove', "-I$FindBin::Bin/../lib", # jwsDancer/bin/../lib "-I$FindBin::Bin/../local/lib/perl5", # jwsDancer/bin/../local/lib/perl5 @ARGV;` [download] All tests run smoothly with modules locally installed and a command like: `perl bin/myprove.pl -lv t/*` Gert	[reply] [d/l] [select]

If I may ask, what actually would have been considered using boilerplate?	[reply]
