Emma – Code Coverage Tool

EMMA measures and reports Java code method, block and line coverage. EMMA distinguishes itself from other tools by providing support for large-scale enterprise software development while it simultaneously keeps individual developers‘ work fast and iterative. Every developer can now get code coverage for free — and they can get it fast. EMMA is so lightweight developers can use it during the process of writing tests instead of waiting for a „test build“. Roubtsov, who developed this code on his own, apart from his Trilogy duties, said this puts code coverage where it belongs: in design and implementation, before the code is checked in.
