Code Coverage for C#/.net

Question

I wonder what options there are for .net (or C# specifically) Code Coverage, especially in the Lower Priced segment?

• NCover
  • Seems to be very popular and looks quite good.
  • Supports statement coverage and branch coverage.
  • $299 for the 64-Bit Version.
  • Older Beta-Versions 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
  • Open Source
  • Supports statement coverage.
• SD Test Coverage
  • Works with 32 and 64 bits, full C# 4.0
  • Handles both small and very large code bases
  • $250.00 for single user license
• JetBrains dotCover
  • "dotCover 1.0 is scheduled for release in late Summer 2010"

Answer 1

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

Answer 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.

Answer 3

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.

Answer 4

See the C# Test Coverage tool from Semantic Designs:

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.

Answer 5

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.

Answer 6

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.

Answer 7

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.

Answer 8

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

Answer 9

TestMatrix is a unit test runner and Code Coverage tool.
