dotCover: Code Coverage for .NET

Testing code for coverage with dotCover
Similar to dotTrace, dotCover works with ReSharper. When you install dotCover, you see several options appear in the ReSharper menu options as well as the Test Runner window. First of all, under ReSharper | Unit Tests menu option, there is a new option to run coverage reports, either for specific tests or for the entire solution. Similarly, the Test Runner Window offers us the same options. You get a new icon to run tests under coverage, as well as a new tab that will display the output of the coverage report. Based on the information you want to obtain, you can run coverage reports on the entire solution or only certain tests. Running on the entire solution will give you a measurement of how much of yout entire code base is covered. In order to do so, you can select Cover All Tests from Solution. You can assign whatever keyboard shortcut you want to this action by selecting the ReSharper_UnitTest_CoverSolution command. Executing the command will run the unit tests and once completed will then proceed to run a coverage report. You can also run coverage on individual tests or classes, by selecting them and choosing to Cover with dotCover. The window groups coverage reports based on the option selected in the drop-down list. dotCover provides you with two measurements: percentage of code covered and number of statements.
