To find lines of code that require test coverage, click on the Line coverage heading and sort it by least coverage. The simplest way to improve your test coverage with the Fine Code Coverage Visual Studio 2022 extension is to identify lines of code that are not covered with tests. Using Fine Code Coverage Visual Studio 2022 Reports Adding Missing Line Coverage Start by setting this value to 10 and increase it if required (or refactor to simplify your code). Code with a value greater than this will appear in the Risk Hotspots tab in the Fine Code Coverage window. Microsoft recommends that a cyclomatic complexity of 10 to 15 is reasonable. Code that makes too many decisions becomes difficult to test and may be susceptible to errors or cognitive complexity that make it difficult to maintain over time.įinal Code Coverage defaults the Microsoft Code Coverage cyclomatic complexity warning to 30. Details of this topic will be explored further in another blog post.Īll a goal-oriented Code Sloth must understand in using Fine Code Coverage in Visual Studio 2022 is that a large cyclomatic complexity number indicates that your code is making many decisions. These decision points can be visualised using a control flow graph. Configuring Cyclomatic ComplexityĬyclomatic complexity is a metric derived from the number of decision points within a given piece of code. This setting can be found in the Fine Code Coverage options, as above. The noisy output from above can be excluded by setting the following in the ModulePathsExclude option. Excluding Noisy Output from Microsoft Code Coverage Note that in doing so, you will see additional assemblies in the Fine Code Coverage window. However, Microsoft have released a free code coverage solution that this tool has integrated with, so navigate to RunMsCodeCoverage in the FineCodeCoverage sections of the Options dialog and set it to yes. The default configuration of Fine Code Coverage is to use the ‘old coverage’ tools. Run your tests again and the test project will disappear. Select the Tools menu -> Options -> Type fine code in the filter -> Select Fine Code Coverage -> set IncludeTestAssembly to false. This is unnecessary, as we won’t be analyzing our tests! In the screenshot above, we can see that the unit testing project itself was included in code coverage.
