我有一个依赖于外部模块的失败测试用例。 我想使用Rhino Mock生成一个被调用函数的报告。
我创建了一个最小的示例来说明我的问题:
using NUnit.Framework;
using Rhino.Mocks;
using System;
namespace StackOverflow_namespace
{
public interface IUsefulService
{
object HiddenAmongManyCalls();
}
public class ThirdPartyBase
{
private int a = 42;
public ThirdPartyBase(IUsefulService service)
{
object liveFastDieYoung = service.HiddenAmongManyCalls();
liveFastDieYoung.Equals(a);
}
}
public class MyParty : ThirdPartyBase
{
public MyParty(IUsefulService service) : base(service)
{
}
}
[TestFixture]
class StackOverflow
{
[Test]
public void Hypothetical()
{
IUsefulService service = MockRepository.GenerateMock<IUsefulService>();
try
{
var party = new MyParty(service);
}
catch(Exception e)
{
string[] calls = MagicallyGetTheCallsThatWereMadeToTheMock();
foreach(var call in calls)
{
//with my visual studio testrunner for nunit 3 I can investigate stored console output
Console.WriteLine(call);
}
Assert.Fail("Excpexted no exception but was '" + e.GetType().Name + "': " + e.Message);
}
}
private string[] MagicallyGetTheCallsThatWereMadeToTheMock()
{
return new[]
{
"This is where I am lost, I do not know how to get the calls from the repository."
};
}
}
}
我尝试在网上找到一些信息但没有成功。
Rhino Mocks是否记录所有调用并且我可以访问该列表?
编辑:
由于我正在寻找我没有期望的调用,因此尝试验证期望未能成功。
我可以使用
GetArgumentsForCallsMadeOn
构建一个调用列表。我可以反射接口。我已经开始为此编写一个方法,但我目前无法看到如何将MethodInfo
转换为Action<T>
。private IEnumerable<string> GetCallsList<Interface>(Interface rhinomock)
{
Type interfaceType = typeof(Interface);
List<MethodInfo> interfaceMethodInfos = new List<MethodInfo>();
List<string> returnInfos = new List<string>();
StringBuilder callbuilder = new StringBuilder();
foreach (var property in interfaceType.GetProperties())
{
interfaceMethodInfos.Add(property.GetGetMethod());
interfaceMethodInfos.Add(property.GetSetMethod());
}
foreach (var method in interfaceType.GetMethods())
{
interfaceMethodInfos.Add(method);
}
foreach (var methodinfo in interfaceMethodInfos)
{
Action<Interface> magic = null; //convert methodinfo into action - still missing
var calls = rhinomock.GetArgumentsForCallsMadeOn(magic); //magic is currently null, here be crash
foreach (var call in calls)
{
bool more = false;
callbuilder.Clear().Append(interfaceType.Name).Append('.').Append(methodinfo.Name).Append('(');
foreach (var parameter in call)
{
if (more){ callbuilder.Append(", "); }
if (null == parameter) { callbuilder.Append("<null>"); }
else { callbuilder.Append(parameter.ToString()); }
more = true;
}
callbuilder.Append(')');
string callInfo = callbuilder.ToString();
returnInfos.Add(callInfo);
}
}
return returnInfos;
}
VerifyAllExpectations
并不能解决你的问题。当你不希望允许出现意外调用时,你需要使用严格模拟(目前使用这种模拟被视为一种不好的做法...)。如果你仍然想要访问记录:可以使用反射或下载Rhinomocks源代码并进行一些修改... - Old Fox
