What can I use for good quality code coverage for

问题:

I wonder what options there are for .NET (or C# specifically) code coverage, especially in the lower priced segment?

I am not looking for recommendations, but for a comparison of products based on facts. I know the following:

• NCover
  • Seems to be very popular and looks quite good
  • Supports statement coverage and branch coverage
  • $480 for \"NCover 3 Complete\"
  • Older beta versions are available for free
• Visual Studio (2008 Pro) | (2005 Team System (Development, Test or Team Suite Editions))
  • Well, it\'s Microsoft so I\'d expect it to work properly
  • Fully integrated into Visual Studio
  • At least $5,469
• PartCover - no further development (moved to OpenCover)
  • Open source
  • Supports statement coverage
• OpenCover - successor to PartCover
  • OpenSource
  • Supports branch and statement coverage
  • 32 and 64 bit support
  • Silverlight support
  • Background
  • Tutorial on The Code Project by the primary developer
  • No .NET Core support yet
• SD Test Coverage

  • $250 for single user license
• JetBrains dotCover
  • $100 for Personal License. Free for user groups, open source projects, students and teachers.
  • Supports statement coverage
  • Silverlight support

• NCrunch

  • $159 for personal license
  • $289 for commercial seat license * Free during beta, to become commercial, pricing unknown future unknown.
  • Code coverage indicators in Visual Studio
  • Continuous (near real time) testing
  • Visual per-test code coverage
  • Performance metrics, parallel multi-core test execution

• NDepend

  • $410 for developer license
  • NDepend can import coverage data from NCover, DotCover, Visual Studio 2017; 2015, 2013, 2012, 2010 and 2008 Code Coverage files.
  • Dependency graph

I use the version of NCover that comes with TestDriven.NET. It will allow you to easily right-click on your unit test class library, and hit \"Test With -> Coverage\", and it will pull up the report.

回答2:

An alternative to NCover can be PartCover, is an open source code coverage tool for .NET very similar to NCover, it includes a console application, a GUI coverage browser, and XSL transforms for use in CC.Net.

Very interesting product.

UPDATE: OpenCover has replaced partcover.

回答3:

JetBrains(of ReSharper fame) has been working on a coverage tool for a little while called dotCover It\'s showing a great deal of promise.

回答4:

I just tested out NCrunch and have to say I am very impressed. It is a continuous testing tool that will add code coverage to your code in Visual Studio at almost real time. At the time as I write this NCrunch is free. It is a little unclear if it going to be free, cost money or be opened source in the future though.

TestCocoon is also pretty nice: http://www.testcocoon.org/index.html with active development and user community:

• Open source (GPL3)
• Supports C/C++/C# cross platform (Linux/Windows/Mac)
• CoverageScanner - Instrumentation during the Generation
• CoverageBrowser - View, Analysis and Management of Code Coverage Result

EDIT:Test cocoon is no longer developed and its creators are now producing a commercial software for C/C++

回答6:

There are pre-release (beta) versions of NCover available for free. They work fine for most cases, especially when combined with NCoverExplorer.

回答7:

Not sure what the difference with the retail NCover, but there is also an NCover project on sourceforge that is of course open source and free.

回答8:

TestMatrix is a unit test runner and Code Coverage tool.

回答9:

See the C# Test Coverage tool from my company, Semantic Designs:

http://www.semanticdesigns.com/Products/TestCoverage/CSharpTestCoverage.html

Very low overhead, handles huge systems of files, intuitive GUI showing coverage on specific files, and generated report with coverage breakdown at method, class and package levels.

Code coverage features, as well as programmable API\'s, come with Visual Studio 2010. Sadly, the only two editions that include the full Code Coverage capabilities are Premium and Ultimate. However, I do believe the API\'s will be available with any edition, so creating code coverage files and writing a viewer for the coverage info would likely be possible.

We\'ve release EAP to dotCover (http://www.jetbrains.com/dotcover) and will be releasing the Beta soon.
