Open Source Code Coverage Tools

A group of Java-based testing tools and JUnit extensions aimed at increasing quality awareness and ease of introduction of testing tools into the development cycle. Examples are Automated documentation, class hierarchy unit testing, and code coverage.

This project provides a meaningful way to increase code coverage of your jUnit and TestNG tests. Unit testing Java Beans can be a tedious task. The goal of this project is to provide an automated way to unit test the getters and setters of a class.

A code coverage console app for wrapping MsTest executed tests for Visual Studio for Testers. The app extracts coverage data from a binary (*.coverage) file, generated by MsTest into an XML file which can be used in your build process.

Easy Coverage is a tool that can dynamically generate unit tests to perform basic verifications, thus leaving more time for the developers. When writing unit tests, developers often have to write the same elementary verifications over and over for most classes. This is tedious and error-prone, and keeps developers away from writing more meaningful unit tests. Easy Coverage is extensible and highly configurable. It can work as a standalone product, or be used with JUnit, which is highly recommended. Support for TestNG is planned. If you want to get started, you should go to the wiki and the quick start.

JUnitMetrics is a tool that enables to measure basic JUnit and Cactus tests metrics (like number of tests, assertions, number of executed assertions). It is great, complementary solution to code coverage tools and mutation testers.

It is a JavaDoc and comment coverage tool. It check the quality of JavaDoc and comments in Java source files. The output is like the EMMA Java code coverage.

A web-based courseware system for programming courses. Provides support for on-line submission testing, static analysis, code coverage, peer and instructional code reviews and grading. Works with projects in any programming language.

Camlp4 extension to check code coverage of any OCaml code

A Unibasic Code Coverage tool. It produces formatted HTML reports on the statement coverage of selected source files. Designed for UniData but should is being ported to UniVerse (still in development, but compiles and works on demonstration programs).

ZK Unit extends JUnit to test your ZK project: ZUL pages, composers, event handlers, constraints and more. Use ZKUnit for test driven development, to achieve code coverage and integration with a continous build system.

A set of scripts, based around doctest, for performing regression testing & code coverage analysis on Python modules.

Unitils Module - Easy way to test if the object validates all the predefined rules.

xCover is a C/C++ library that uses low-impact syntactic signalling to detect code coverage in a code base at runtime
