: (which isn't really CodeCoverage, but it's related)
for .NET (DotNet):
- JesTer @ http://jester.sourceforge.net/ - changes your code, and then runs your tests. (If arbitrary changes to the code don't break the tests, then is your code sufficiently tested?)
- OpenCover @ https://github.com/sawilde/opencover - OpenSource (MIT licence) A code coverage tool for .NET 2 and above, support for 32 and 64 processes with both branch and sequence points
- Clover.NET @ http://www.cenqua.com/clover.net/ - ClosedSource (but free for use on OpenSource projects), C# and VB.NET, statement, method and branch coverage, from command line, Visual Studio, and NAnt (preliminary mono support)
- NCover @ http://ncover.sourceforge.net/ - OpenSource, path coverage, NUnit, NAnt
- CoverageEye?.NET @ http://www.gotdotnet.com/Community/UserSamples/Details.aspx?SampleGuid=881a36c6-6f45-4485-a94e-060130687151 - uses a COM component to leverage the .NET profiling API
- "DevPartner? Studio Professional Edition" @ http://www.compuware.com/products/devpartner/1563_ENG_HTML.htm - $$$
- "Perform Code Coverage Analysis with .NET to Ensure Thorough Application Testing", an MSDN article on building "A custom code coverage tool" @ http://msdn.microsoft.com/msdnmag/issues/04/04/CodeCoverageAnalysis/default.aspx

- "dotCover" http://www.jetbrains.com/dotcover/ Closed source, free license for OSS projects
I have started to use Hansel, http://hansel.sourceforge.net/
, an open source CodeCoverage
tool which integrates seamlessly with JavaUnit
. Hansel is a TestDecorator?
. I add test classes incrementally to a coverage test suite with Hansel. We were already quite thorough on unit testing, but actually measuring coverage enabled us to remove more production code, add some tests, and ReFactor
code. -- WillemVanDenEnde
I have started using jcoverage, http://www.jcoverage.com/
, which is also an open-source CodeCoverage
tool. It integrates with Ant using its own custom tasks and can report on both line and branch coverage. I have been quite impressed with it so far. -- CraigPardey?
I have started using Clover, http://www.thecortex.net/clover/
, which isn't open source, but is free for open source developers and not that expensive for commercial use. Unlike Hansel, you don't need any magic in your test-suites to make it work, ItJustWorks
. Clover can generate HTML/PDF/XML reports and it integrates with EclipseIde
. After just couple of days, I'm very impressed. -- JuhaKomulainen
"The Clover tool's integration with IntelliJ makes it *very* easy to click on modules with low coverage and see what was covered and what was not." -- a comment by RobertMartin
Just came across a slew of tools/utilities from the GroboUtils
project @ sourceforge. The intentions are certainly impressive. Anybody had a chance to check it out? http://groboutils.sourceforge.net/
A good comparison on CodeCoverage
tools integrating with Ant can be found at http://www.javaranch.com/newsletter/200401/IntroToCodeCoverage.html
A list of java open source coverage tools can be found at: http://java-source.net/open-source/code-coverage
A good evaluation of about ten different CodeCoverage
Tools is at http://europetravelogue.com/blog/pivot/entry.php?id=41
. The reviewer found Emma and Clover to be the best for his needs.
Common Lisp has Waters' COVER package: http://www-cgi.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/lang/lisp/code/testing/cover/0.html
It's rather compact compared to some of the other tools described on this Wiki page. -- PaulDietz
