我开始玩 xUnit 和 Moq 并且想知道我是否做得对。

我应该这样写测试：

[Fact]
public void ForWebShouldReturnDev()
{
    // Arrange
    var server = new Mock<HttpServerUtilityBase>();
    server.SetupSequence(s => s.MachineName).Returns("t11466").Returns("localhost").Returns("webdev");

    var context = new Mock<HttpContextBase>();
    context.SetupGet(c => c.Server).Returns(server.Object);

    var service = new EnvironmentService(context.Object, null);

    // Act / Assert
    service.GetApplicationEnvironment().Should().Be(ApplicationEnvironment.Dev);
    service.GetApplicationEnvironment().Should().Be(ApplicationEnvironment.Dev);
    service.GetApplicationEnvironment().Should().Be(ApplicationEnvironment.Dev);
}

或者更像这样：

[Fact]
public void ForWebShouldReturnDev()
{
    // Arrange
    var server = new Mock<HttpServerUtilityBase>();

    var context = new Mock<HttpContextBase>();
    context.SetupGet(c => c.Server).Returns(server.Object);

    var service = new EnvironmentService(context.Object, null);

    // Act / Assert
    foreach (var name in new string[] { "t11466", "localhost", "webdev" })
    {
        server.Setup(s => s.MachineName).Returns(name);
        service.GetApplicationEnvironment().Should().Be(ApplicationEnvironment.Dev);
    }
}

我知道您应该每次测试只测试一个代码单元，但是当测试中有变量时，循环断言是否可以？

我无法找出测试这些类型事物的最佳方法。

作为记录，下面是被测的实际代码：

// The constructor for the application environment
public EnvironmentService(HttpContextBase httpContext, IEnvironment environment)
{
    this.environment = environment;
    this.httpContext = httpContext;
}

private readonly Dictionary<ApplicationEnvironment, string> applicationEnvironments = new Dictionary<ApplicationEnvironment, string>() {
    { ApplicationEnvironment.Dev, "DEV" },
    { ApplicationEnvironment.Test, "TEST" },
    { ApplicationEnvironment.QA, "QA" },
    { ApplicationEnvironment.Prod, "PROD" }
};

public ApplicationEnvironment GetApplicationEnvironment()
{
    var machine = IsWeb ? httpContext.Server.MachineName : environment.GetCommandLineArgs().First();

    return applicationEnvironments.FirstOrDefault(x => machine.ToUpper().Contains(x.Value)).Key;
}

关于起订量的更多细节，我还有另一个问题。

Moq 有什么好的资源吗，他们的文档很薄。

如果使用 NUnit，我会亲自使用该[TestCase]属性，这样您仍在测试一件事，但要测试一组案例。

xUnit 中存在类似的东西， 在这篇 SO 帖子中的这篇文章中进行了解释
