Test::DBIx::Class::SchemaManager - Manages a DBIx::Class::SchemaManager for Testing


This class is a helper for Test::DBIx::Class. Basically it is a type of wrapper or adaptor for your schema so we can more easily and quickly deploy it and cleanup it for the purposes of automated testing.

You shouldn't need to use anything here. However, we do define %ENV variables that you might be interested in using (although its probably best to define inline configuration or use a configuration file).


Set to a true value will force dropping tables in the deploy phase. This will generate warnings in a database (like sqlite) that can't detect if a table exists before attempting to drop it. Safe for Mysql though.


Usually at the end of tests we cleanup your database and remove all the tables created, etc. Sometimes you might want to preserve the database after testing so that you can 'poke around'. Personally I think it's better to write tests for the poking, but sometimes you just need a quick look.

Please Note that KEEP_DB is not intended for use as a way to preserve deployed databases across tests or test runs. I realize you may wish to try this as a way to reduce testing time, since starting and deploying databases can be time consuming, however it negates the goal we have to properly isolate the test cases.

If there is tremendous need for this type of feature, we may in the future try to develop a good working system. For now I recomment using the reset_schema (see "reset_schema" in Test::DBIx::Class for more) and subtests if you want to try this for a given test run..
