您在单元测试中检查 HttpVerbs 吗？

发布于 07-25 06:06 字数 155 浏览 18 评论 0原文

在查看标准 ASP.MVC Web 项目模板附带的单元测试时，我注意到这些测试不会测试每个操作方法上是否设置了正确的 HttpVerbs 属性。

通过反射来测试这一点非常容易，但问题是它是否值得付出努力。您是否在单元测试中检查 HttpVerbs，还是将其留给集成测试？

您还可以使用 MvcContrib.TestHelper 通过操作来测试路由。

    [TestMethod]
    public void ShouldConfirmRouteForNewObjectWithPost()
    {
        "~/Object/New".WithMethod(HttpVerbs.Post).ShouldMapTo<ObjectController>(x => x.New());
    }

You could also use the MvcContrib.TestHelper to test the route with actions.

    [TestMethod]
    public void ShouldConfirmRouteForNewObjectWithPost()
    {
        "~/Object/New".WithMethod(HttpVerbs.Post).ShouldMapTo<ObjectController>(x => x.New());
    }

如果其他人发现这个问题：我已经开始在单元测试中检查所有操作方法接受属性。稍微反思一下就可以解决问题。如果您也想这样做，这里有一些代码：

protected void CheckAcceptVerbs<TControllerType>(string methodName, HttpVerbs verbs)
{              
    CheckAcceptVerbs(methodName, typeof(TControllerType).GetMethod(methodName, BindingFlags.Public|BindingFlags.Instance,null,new Type[]{},null), verbs);
}

protected void CheckAcceptVerbs<TControllerType>(string methodName, Type[] ActionMethodParameterTypes, HttpVerbs verbs)
{
    CheckAcceptVerbs(methodName, typeof(TControllerType).GetMethod(methodName, BindingFlags.Public | BindingFlags.Instance, null, ActionMethodParameterTypes, null), verbs);
}

private void CheckAcceptVerbs<TControllerType>(string methodName, MethodInfo actionMethod, HttpVerbs verbs)
{
    Assert.IsNotNull(actionMethod, "Could not find action method " + methodName);
    var attribute =
        (AcceptVerbsAttribute)
        actionMethod.GetCustomAttributes(false).FirstOrDefault(
            c => c.GetType() == typeof(AcceptVerbsAttribute));


    if (attribute == null)
    {
        Assert.AreEqual(HttpVerbs.Get, verbs);
        return;
    }

    Assert.IsTrue(HttpVerbsEnumToArray(verbs).IsEqualTo(attribute.Verbs));
}

第一个方法适用于不带参数的操作方法，第二个方法适用于带参数的操作方法。您也可以直接使用第三种方法，但我将前两个重载编写为便利函数。

In case someone else finds this question: I've started checking all of my action method accept attributes in my unit tests. A bit of reflection does the trick just fine. Here's some code if you'd like to do this as well:

protected void CheckAcceptVerbs<TControllerType>(string methodName, HttpVerbs verbs)
{              
    CheckAcceptVerbs(methodName, typeof(TControllerType).GetMethod(methodName, BindingFlags.Public|BindingFlags.Instance,null,new Type[]{},null), verbs);
}

protected void CheckAcceptVerbs<TControllerType>(string methodName, Type[] ActionMethodParameterTypes, HttpVerbs verbs)
{
    CheckAcceptVerbs(methodName, typeof(TControllerType).GetMethod(methodName, BindingFlags.Public | BindingFlags.Instance, null, ActionMethodParameterTypes, null), verbs);
}

private void CheckAcceptVerbs<TControllerType>(string methodName, MethodInfo actionMethod, HttpVerbs verbs)
{
    Assert.IsNotNull(actionMethod, "Could not find action method " + methodName);
    var attribute =
        (AcceptVerbsAttribute)
        actionMethod.GetCustomAttributes(false).FirstOrDefault(
            c => c.GetType() == typeof(AcceptVerbsAttribute));


    if (attribute == null)
    {
        Assert.AreEqual(HttpVerbs.Get, verbs);
        return;
    }

    Assert.IsTrue(HttpVerbsEnumToArray(verbs).IsEqualTo(attribute.Verbs));
}

The first method is for action methods without parameters, the second is for those with parameters. You can also just use the third method directly, but I wrote the first two overloads as convenience functions.
