EfficiencyGuardian extracts callgrind efficiency measures from individual CppUnit test cases to detect efficiency regresion. It includes a data mining web tool to browse historic results and TestFarm integration for unattended execution on commit.
Auto Proxy Filter Test (APFT) automates the testing of safe and unsafe URLs against a content filtering proxy (such as Dansguardian) and helps prevent regressions. APFT is useful to people who are designing filter rules.
Simloc is the tool intended for finding similar chunks (blocks) of code. It could be used in reverse software engineering. It is faster than SimScan, find better blocks than PMD/CPD (not just exact blocks also similar) and could be runed at GRID.
