TARGETED REGRESSION TESTING

A software testing method. In particular implementations, a method includes accessing a first database of one or more bug entries, wherein each bug entry comprises information characterizing a bug, an associated code component, and a test script; and a mapping between the component and one or more scripts that test the code component; for one or more bug entries in the first database, determining if the bug is a new bug; if the bug is not a new bug, determining if the test script is new relative to the bug; and if the bug is a new bug or if the test script is new relative to the bug, accessing a second database of the script-to-component mappings to add a mapping between the test script and the associated code component of a respective bug entry.
