Test::More and XML::Simple

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

I have been trying to write tests for a module that use's XML::Simple. However, Test::More and Test::Simple as well do not play well with XML::Simple.

There is a call to the built in function "lock" deep inside XML::Simple that conflicts with the thread-safe version of "lock" that is used by Test::More.

For some reason, Test::More imports itself into all the neighboring namespaces and packages. How do I work around this behavior?

Are you by chance running an incredibly old version of XML::Simple? The lock() function was added to allow XML::Simple to be thread safe under the 5.005 threading model while still working with older Perls. That threading model was replaced with a new model in Perl 5.6 and the lock function was removed from XML Simple in October 2002. Given that XML::Simple uses Test::More extensively in its own test suite, I'm pretty sure they get along OK :-)	[reply]

My version of XML::Simple came with the Active State Perl. It is version 1.06 and I see the current version of XML::Simple is 2.12. However, now I can't seem to recreate the errors I was getting. :I Thanks	[reply]

Test::More exports plenty of stuff by default but you can control this by doing something like `use Test::More (tests => 27, import => ['is' 'like']);` [download] the stuff in the `[]` tells it what symbols to export. Test::More uses the standard Exporter.pm to export symbols, it just takes the list of things to export in a slightly different way. Test::More does not export anything into a package unless that package asks for it with a `use`. That said, Test::More doesn't define a subroutine lock() so your problem is something else.

Test::Builder does have `lock()` and `share()`, but they should be sufficiently encapsulated. Perhaps the OP's Perl configuration supports ithreads.	[reply] [d/l] [select]

Can you provide a little more details? it's best to show how you're using XML::Simple and the test code. I'm using Test:More to test my application which uses XML::Simple, haven't seen any problems yet, but I probably don't have your locking issue. Anyhow, it's pretty hard to tell from what you wrote.
