A quick way to test a perl module with a new method is to use a command like the following:
$ perl -MeTechTips::IssueTracking::ClearQuest -we '$tr = eTechtips::IssueTracking::ClearQuest->new();'
This will test the new and ensure that you have the correct syntax if you do not have an easy test environment for your code, for example as I do not have a ClearQuest instance to test with.
