Running regression tests

To run regression tests you need to execute the class PDQ.java, which lies in the regression project, as an application. The command line parameters should be:

 >  PdqRegression -m [mode] -i [folder]

Folder: either a folder with a schema.xml and query.xml file in it, or a root directory containing many of such subfolders.

If you are running PDQ, rather than running an existing regression test, then in a new folder create schema and query XML files, add case.properties and run this folder as above.

Available modes:

• planner: creates the expected plan XML file. If it is already exists compares the result with it.
• runtime: executes the expected plan XML file.
• full: first two in sequence.
