Question

我创建了以下测试类：

package Test::DB;

# $Id$
#

use strict;
use warnings;

our $VERSION = '0.01';

use Carp;
use English '-no_match_vars';
use Test::Most;

use base 'Test::Class';

sub startup : Tests(startup) {
    eval {
        require esp_libs_db;

        esp_libs_db->import;

        1;
    } or Carp::croak($EVAL_ERROR);

    return 1;
}

sub connect : Tests(2) {
    can_ok 'esp_libs_db', 'espDbConnect';

    my $schema = 'test_schema';

    throws_ok { espDbConnect($schema) }
      qr/Cannot locate database ($schema) connection file./,
      'dies when connection file does not exist';

    return 1;
}

1;

当我来运行测试时，我得到以下输出：

t/run.t ..
#
# Test::DB->connect
1..2
ok 1 - esp_libs_db->can('espDbConnect')
not ok 2 - dies when connection file does not exist

#   Failed test 'dies when connection file does not exist'

Dubious, test returned 1 (wstat 256, 0x100)

我不明白为什么第二次测试失败的时候应该非常清楚地传递

Answer 1

(和)是正则表达式中的特殊字符，请尝试转义它们：

qr/Cannot locate database \($schema\) connection file./

为什么我的Perl测试失败？
