我在一个名为ParserTests.pl的文件中进行了测试.我试图在模块LogParser.pm中测试子程序(解析)

sub parse {
    my ($self) = @_;
    my $rr = $self->getRR;
    while(1) {
        my $result = $self->parseCommitSet();
        if ($result eq 2) {
            last;
        }
        my $printStatus = $self->printOut($result);
        if (!$printStatus) {
            say "Problem occurred with writing to output";
            return 0;
        }
        $self->setRR(ReportRecord->new());
    }
    return 1;
}

我试图模拟printOut,以便它总是返回true.我想要做的是这样的：

#! /usr/bin/perl
use v5.10.0;
use strict;
use warnings;
use Test::More 'no_plan';
use Test::MockObject;
use LogParser;
{other tests…}
my $mock = Test::MockObject->new();
$mock->set_true('LogParser::printOut');
my $test100FH = getTestFH($test100SetsNoPrev);
$logParser = LogParser->new($test100FH);
is($logParser->parse,1,"im ok?");
close $test100FH;

但是这个测试失败了.你能告诉我为什么并指出我正确的道路让我在测试parse()时正常工作吗？我读了一堆文档,但这样的事情仍然有点不清楚.

错误是

Can't use an undefined value as a symbol reference at /Users/achu/Documents/workspace/Perl_Script/LogParser.pm line 241,<$fh> line 8371.
# Looks like your test exited with 25 just after 91.

那一行(第241行)在printOut子程序中,虽然这意味着它没有像我想要的那样模仿那个子程序.我究竟做错了什么？
