如何使用test::WWW::Mechanical::PSGI测试Dancer应用程序

Question

我不确定为www mechanize设置脚本应用程序的正确方法。我确实尝试了至少一种可行的替代方案，但我正在尝试通过测试进行配置，以便使用测试套件使日志记录更安静。

#!/usr/bin/perl
use strict;
use warnings;
use Dancer qw(:syntax);
use MyApp;
use Test::More;
use Test::WWW::Mechanize::PSGI;
set apphandler => 'PSGI';
set log => 'warning';
set logger => 'note';
my $mech = Test::WWW::Mechanize::PSGI->new(
    app => dance, # app => do('bin/app.pl'), #
);
$mech->get_ok('/login') or diag $mech->content;
done_testing;

在脚本上运行do似乎可以运行测试，但日志变量设置不正确，同时似乎还有更好的方法。

更新

我想我可能离解决方案越来越近了。。。

#!/usr/bin/perl
use strict;
use warnings;
use FindBin;
use Cwd qw( realpath );
use Dancer qw(:syntax);
use MyApp;
use Test::More;
use Test::WWW::Mechanize::PSGI;
set apphandler => 'PSGI';
my $appdir = realpath( "$FindBin::Bin/.." );
my $mech = Test::WWW::Mechanize::PSGI->new(
    app => sub {
        my $env = shift;
        setting(
            appname => 'MyApp',
            appdir => $appdir,
        );
        load_app 'MyApp';
        config->{environment} = 'test'; # setting test env specific in test.yml detected ok
        Dancer::Config->load;
        my $request = Dancer::Request->new( env => $env );
        Dancer->dance( $request );
    }
);
$mech->get_ok('/login') or diag $mech->content;

done_testing;

我从Dancer:：Plack PSGI的部署文档中得到了这个。然而，我在测试中得到了500的错误。

DBI错误在这里并不相关，但它们是我得到的错误输出的一部分。我不明白为什么它找不到/login/default.tt。我猜问题是它不知道我的视图文件夹在哪里，因为有问题的模板在views/login/default.tt。即使在plackup上运行，此视图在浏览器中也能正常工作。我被难住了。

Answer 1

这是在我将t/views符号链接到views的情况下工作的。我目前认为这可能是错误的结果，所以我在这里提交了一个，并创建了这个测试用例存储库。

#!/usr/bin/perl
use strict;
use warnings;
BEGIN {
    use Test::More;
    use namespace::clean qw( pass );
}
use FindBin;
use Cwd qw( realpath );
use Dancer qw( :syntax );
#use MyApp;
use Test::WWW::Mechanize::PSGI;
set apphandler => 'PSGI';
my $appdir = realpath( "$FindBin::Bin/.." );
my $mech = Test::WWW::Mechanize::PSGI->new(
    app => sub {
        my $env = shift;
        setting(
            appname => 'MyApp',
            appdir => $appdir,
        );
        load_app 'MyApp';
        config->{environment} = 'test';
        Dancer::Config->load;
        my $request = Dancer::Request->new( env => $env );
        Dancer->dance( $request );
    }
);
$mech->get_ok('/') or diag $mech->content;
done_testing;

我设置了记录器并登录到environments/test.yml。

我仍然会遇到这些错误，我希望看到它们得到修复，但不确定是什么原因造成的。

希望有人能给我一个比我所能给出的更好的答案。
