This is an update to an earlier post I wrote about the adventures I had in creating and using a mock
LWP::UserAgent for testing purposes. The ever-vigilant mst overheard a conversation on the same topic, and jumped in. He pointed out that
Test::MockObject (and everything using it) overrides
UNIVERSAL::isa in a way that hides bugs. Because it can hide bugs, it is definitely not safe to use in a test suite, where you’re trying to uncover bugs.
The bottom line
Instead of following my earlier advice, use
Test::LWP::UserAgent, a new module which avoids
Test::MockObject and offers a better interface (in particular, the nonsense with subtypes is no longer needed) for creating and using mock
