Unit testing .NET MAUI ViewModels involves isolating the logic using xUnit and mocking dependencies like INavigationService. This allows you to validate ViewModel behavior deterministically without running the actual UI layer.

Mocking MAUI services like IConnectivity in xUnit is done using the Moq library. You simulate service dependencies to test how your ViewModels react to different connectivity states within your test project.

Setting up a .NET MAUI test project requires adding xUnit and Moq dependencies, configuring target frameworks like net9.0, and handling conditional OutputType. You then run tests using dotnet test in the dedicated project.

Yes, you can use Moq and xUnit for MAUI testing on net10.0. The testing patterns support both net9.0 and net10.0 target frameworks, ensuring your test project aligns with your MAUI application's configuration.

Isolating MAUI services during ViewModel unit testing prevents external dependencies from causing flaky tests. By mocking services like navigation, you ensure reproducible and deterministic execution for your logic validation.

MAUI unit testing supports code coverage analysis to measure test effectiveness and on-device test runners for execution. These features help validate application logic across different testing environments and scenarios.
