Does Visual Studio have code coverage for unit tests

Question

I am using Visual nbsp Studio nbsp 2015 Community edition  and I know that it has the option to create unit tests to test the code  but I don t see the option to test the code coverage  so I would like to know if Visual Studio has this option or if I have to use a third-party plugin   If I have to use a third-party solution  would that be a good option

Only Visual Studio 2015 Enterprise has code coverage built-in. See the feature matrix for details.

You can use the OpenCover.UI extension for code coverage check inside Visual Studio. It supports MSTest, nUnit, and xUnit.

The new version can be downloaded from here (release notes).

For anyone that is looking for an easy solution in Visual Studio Community 2019  Fine Code Coverage is simple but it works well  It cannot give accurate numbers on the precise coverage  but it will tell which lines are being covered with green red gutters

As already mentioned you can use Fine Code Coverage that visualize coverlet output  If you create a xunit test project  dotnet new xunit  you ll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every  NET Core and  gt    NET 5 applications  Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet  OpenCover  dotCover  Visual Studio  NCover  Cobertura  JaCoCo  Clover  gcov or lcov into human readable reports in various formats  Example report   While the article focuses on C  and xUnit as the test framework  both MSTest and NUnit would also work  Guide  https   docs microsoft com en-us dotnet core testing unit-testing-code-coverage tabs windows generate-reports If you want code coverage in  xml files you can run any of these commands  dotnet test --collect  quot XPlat Code Coverage quot   dotnet test  p CollectCoverage true  p CoverletOutputFormat cobertura

Toni s answer is very useful  but I thought a quick start for total beginners to test coverage assessment  like I am    As already mentioned  Visual Studio Professional and Community Editions do not have built-in test coverage support  However  it can be obtained quite easily  I will write step-by-step configuration for use with NUnit tests within Visual Studion 2015 Professional    Install OpenCover NUGet component using NuGet interface Get OpenCoverUI extension  This can be installed directly from Visual Studio by using Tools -  Extensions and Updates Configure OpenCoverUI to use the appropriate executables  by accessing Tools -  Options -  OpenCover UI Options -  General   NUnit Path  must point to the  nunit-console exe file  This can be found only within NUnit 2 xx version  which can be downloaded from here   OpenCover Path  this should point to the installed package  usually  lt solution path gt  packages OpenCover 4 6 519 tools OpenCover Console exe   Install ReportGenerator NUGet package Access OpenCover Test Explorer from OpenCover menu  Try discovering tests from there  If it fails  check Output windows for more details  Check OpenCover Results  within OpenCover menu  for more details  It will output details such as Code Coverage in a tree based view  You can also highlight code that is or is not covered  small icon in the top-left     NOTE  as mentioned  OpenCoverUI does not support latest major version of NUnit  3 xx   However  if nothing specific to this version is used within tests  it will work with no problems  regardless of having installed NUnit 3 xx version   This covers the quick start  As already mentioned in the comments  for more advanced configuration and automation check this article
