Pc_find_tests script

Pc_find_tests is a script that automates coverage-based regression testing in a ClearCase environment. The script queries ClearCase to find out which files have been changed in the source code, then uses coverage data that you create from your tests using PureCoverage to select and execute the tests that will do the best job of validating the changed code. You can download the script and customize it for your own project using the information in this demo. Pc_find_tests will be included in future releases of PurifyPlus beginning with version 7.0.0.0-012.
