FluentAssertions Skill

FluentAssertions provides a fluent API for expressing test assertions in C#. In VanDaemon, it's used alongside xUnit and Moq for testing services, controllers, plugins, and the JsonFileStore persistence layer. The library produces clear failure messages that explain exactly what went wrong.

// From VanDaemon test patterns
result.Should().NotBeNull();
result.Should().Be(expectedValue);
tank.CurrentLevel.Should().BeInRange(0, 100);
tank.IsActive.Should().BeTrue();

Collection Assertions
