1. A method in a host organization, the method comprising: initiating a test sequence against a production database within the host organization, wherein the test sequence specifies: a) new data for insertion into the production database during the test sequence, and b) one or more test queries against the production database during the test sequence; performing a database transaction to insert the new data into the production database without committing the new data to the production database; recording names of one or more objects corresponding to the inserted new data, the one or more objects created as part of the transaction to insert the new data into the production database within a transaction entity object map; modifying the one or more test queries specified by the test sequence to no longer query against the production database by substituting the one or more test queries with references to the names of the one or more objects in operating memory separate from information stored within the production database; and executing the one or more modified test queries.
