Test/MockDBI version 0.70 ========================= Test::MockDBI lets you test DBI interfaces by mocking-up the DBI interface with Test::MockObject in any way you choose. Standard output of the resulting program can then be examined as to whether your program correctly uses the DBI. Mock DBI interfaces like Test::MockDBI improve upon DBI tracing facilities like DBI::trace() and DBD::Mock, as you can modify the behavior of the DBI at the interface in (nearly) any way you choose. There are 3 basic ways to change DBI behavior with Test::MockDBI: bad_method Force a DBI method to fail when the current SQL matches the supplied pattern. bad_param Force a DBI method to fail when the current input parameters match the supplied pattern. set retval Force specific return values when the current SQL matches the supplied pattern. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install Makefile.PL will ask you for DBI configuration parameters, placing them into ./DBI.cfg. This DBI.cfg is not removed even by "make distclean", which should make repeated testing a little easier. DEPENDENCIES This module requires these other modules and libraries: DBI Test::MockObject Scalar::Util Carp Test::Warn Test::More Test::MockDBI has been tested with Test::MockObject v0.14 on Linux. WHY CHOOSE Test::MockDBI OVER DBI::trace() OR DBD::Mock? Test::MockDBI has a major advantage over DBI::trace() or DBD::Mock -- Test::MockDBI lets you change how the mocked DBI functions behave, along with modifying what data is returned by the mocked DBI functions. These changes and modifications can be made specific to particular SQL statement patterns. This ability to modify DBI function behavior and DBI-returned data makes it easier to test code that has different branches for different DBI behaviors -- you can test that a failure within DBI or returned DB data that is different than normal is processed correctly by your module or program. If you are taking over a large code base, Test::MockDBI will help in understanding the code by allowing you to safely check how the code behaves under different database conditions without modifying any databases (production or otherwise).
