The databases/p5-DBD-Mock port
p5-DBD-Mock-1.55p0 – mock database driver for testing
Testing with databases can be tricky. If you are developing a system
married to a single database then you can make some assumptions about
your environment and ask the user to provide relevant connection
information. But if you need to test a framework that uses DBI,
particularly a framework that uses different types of persistence
schemes, then it may be more useful to simply verify what the framework
is trying to do -- ensure the right SQL is generated and that the
correct parameters are bound.
DBD::Mock makes it easy to just modify your configuration (presumably
held outside your code) and just use it instead of DBD::Foo (like
DBD::Pg or DBD::mysql) in your framework.
