如何单元测试GlassController操作,该操作返回获取模型的视图

glass-mapper sitecore-mvc sitecore8 moq c#

user3034243 · 技术社区 · 8 年前

我是一名sitecore开发者,我想创建一个示例sitecore helix单元测试项目,用于测试我们的“HomeBottomContentController”控制器:

    public class HomeBottomContentController : GlassController
    {
        private readonly ISitecoreContext _iSitecoreContext;
        public HomeBottomContentController(ISitecoreContext iSitecoreContext)
        {
            _iSitecoreContext = iSitecoreContext;
        }

        public override ActionResult Index()
        {
            var model = _iSitecoreContext.GetCurrentItem<Home_Control>();
            return View("~/Views/HomeBottomContent/HomeBottomContent.cshtml", model);
        }
    }

namespace WTW.Feature.HomeBottomContent.Tests
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void Test_ISitecoreContextInsertion()
        {
            var iSitecoreContext = Mock.Of<Glass.Mapper.Sc.ISitecoreContext>();
            HomeBottomContentController controllerUnderTest = new HomeBottomContentController(iSitecoreContext);
            var result = controllerUnderTest.Index() as ViewResult;
            Assert.IsNotNull(result);
        }
    }
}

该测试确实通过,意味着“结果”不为空;然而,问题是,当我进入Index()代码时,我看到“model”变量为空

    var model = _iSitecoreContext.GetCurrentItem<Home_Control>();

我的问题是,我如何准确地更改此代码以确保该行中的“模型”不会变为null?如何在单元测试代码中为iSitecoreContext“模拟”一个项,使其具有一个“Home\u控件”模板,其字段具有合法值?这是正确的方法吗?我发现的大多数在线资源都没有类似的场景,我正在寻找尽可能最短的代码。

我的另一个问题是,如果声明了SitecoreContext,我如何在我的[TestMethod]中测试下面的Index()方法 在…内

public override ActionResult Index()
{
    var context = new SitecoreContext();
    var model = context.GetCurrentItem<Home_Control>();
    return View("~/Views/HomeBottomContent/HomeBottomContent.cshtml", model);
}

在这种情况下,您需要在模拟的依赖项上模拟所需的行为

[TestClass]
public class UnitTest1 {
    [TestMethod]
    public void Test_ISitecoreContextInsertion() {
        //Arrange
        var model = new Home_Control() {
            //...populate as needed
        }
        var iSitecoreContext = new Mock<Glass.Mapper.Sc.ISitecoreContext>();
        //Setup the method to return a model when called.
        iSitecoreContext.Setup(_ => _.GetCurrentItem<Home_Control>()).Returns(model);
        var controllerUnderTest = new HomeBottomContentController(iSitecoreContext.Object);

        //Act
        var result = controllerUnderTest.Index() as ViewResult;

        //Assert
        Assert.IsNotNull(result);
        Assert.IsNotNull(result.Model);
        //...other assertions.
    }
}

在动作中创建语境将其与语境紧密结合,几乎不可能模仿。这就是注入显式依赖项的原因

    public override ActionResult Index()

        var model = this.GetCurrentItem();

    protected virtual Home_Control GetCurrentItem()

        public FakeHomeBottomContentController(ISitecoreContext iSitecoreContext) : base(iSitecoreContext) 
        {
        }

        protected override Home_Control GetCurrentItem()
        {
            // return instance of Home_Control type
            // e.g.         
            return new Home_Control();
        }
    }
