The document outlines testing protocols for changes made to the RPR6320 Assurant transmission program. It describes testing at various levels, from unit testing using small test data to full regression testing against all production data. Key tests include: comparing output files from the new and current versions line by line; comparing system logs and comment table entries; and superc comparisons of source code and output files. Any differences found must be justified based on the intended program changes. The goal is to ensure the transmission accuracy is maintained before the new version is moved to production.
