Enable code coverage in Visual Studio

  • Artykuł

For some reason, every time that I want to enable code coverage for a library that I’m unit testing, I found hard to remember how to enable this fabulous feature.

Here are the steps (that work for me):

  1. Double click the [Local].testsettings file in the Solutions Items folder in the Solution Explorer window.
  2. In the "Test Settings" dialog, choose the "Data and Diagnostics" item.
  3. In the list of roles, select "Code Coverage" [Figure 1] and immediately click the '"Configure" button.
  4. In the "Code Coverage Detail" [Figure 2] dialog select the assemblies to instrument for code coverage.
  5. Run your test scenario and in the "Test Tools" toolbar, click the icon "Code Coverage Results".
  6. Done.

    @aractnido thanks for the nice summary, short and useful! @rupesh not all versions of Visual Studion include this feature. I had to get the Ultimate Edition to use the code coverage feature

    Thanks for circling everything.  That didn't even look like a button, so my eyes never went there!  I'm getting coverage info now!
