我正在寻找ac#generator,它可以生成随机单词,句子,由多个单词/段落给出的段落以及某些语法,如地址,数字,邮政编码/邮政编码,国家,电话号码,电子邮件地址.

我的目标是能够对一些自定义HtmlHelper扩展进行单元测试 - 这些扩展在内部使用RenderPartial.

我尝试使用上面的方法来模拟HtmlHelper.但是,我遇到了Null值异常."参数名称:视图"

任何人都有任何想法？谢谢.

以下是代码的想法:

    [TestMethod]
    public void TestMethod1()
    {
        var helper = CreateHtmlHelper(new ViewDataDictionary());
        helper.RenderPartial("Test");  // supposingly this line is within a method to be tested
        Assert.AreEqual("test", helper.ViewContext.Writer.ToString());
    }


    public static HtmlHelper CreateHtmlHelper(ViewDataDictionary vd)
    {
        Mock<ViewContext> mockViewContext = new Mock<ViewContext>(
            new ControllerContext(
                new Mock<HttpContextBase>().Object,
                new RouteData(),
                new Mock<ControllerBase>().Object),
            new Mock<IView>().Object,
            vd,
            new TempDataDictionary(),
            new StringWriter());
        var mockViewDataContainer = new Mock<IViewDataContainer>();
        mockViewDataContainer.Setup(v => v.ViewData)
            .Returns(vd);
        return new HtmlHelper(mockViewContext.Object,
                                mockViewDataContainer.Object);
    }

public class Parent
{
    public virtual Parent me()
    {
        return this;
    }
}

public class Child : Parent
{
}

new Child().me()返回一个Parent对象.我需要让它返回Child对象本身(不使用扩展和泛型)？
