下面,我有一个要测试的对象的代码。我在测试中使用了部分mock,并希望在测试GenerateReport方法时模拟对InsertData的调用。出于某种原因,我的测试继续进行到InsertData到DoSomeStuff,但在Path.Combine行失败。我错过了什么?
public class MyClass : IMyClass
{
private readonly IMyClassDataProvider _myClassDataProvider;
public virtual string WorkingDirectory { get; set; }
public MyClass(IMyClassDataProvider myClassDataProvider)
{
_myClassDataProvider = myClassDataProvider;
}
internal virtual void ValidateWorkingDirectory()
{
if (string.IsNullOrEmpty(WorkingDirectory))
{
throw new ApplicationException("Must set Working Directory before any method calls.");
}
}
public virtual void GenerateReport(vars)
{
ValidateWorkingDirectory();
InsertData(_myClassDataProvider.GetData(vars), "ReportName");
//want to mock the call above
}
internal virtual void InsertData(DataSet analysis, string fileName)
{
DoSomeStuff();
}
private static void DoSomeStuff()
{
string fileName = FileNameProvider.Get();
Path.Combine(WorkingDirectory, fileName); //fails here!
}
}
[TestFixture]
public class MyClassTests : TestFixtureBase
{
private MockRepository _mocks;
private IMyClassDataProvider _myClassDataProvider;
private MyClass _myClass;
private var _vars;
[SetUp]
protected void Init()
{
_mocks = new MockRepository();
_myClassDataProvider = _mocks.StrictMock<IMyClassDataProvider >();
_myClass = _mocks.PartialMock<MyClass>(_myClassDataProvider);
_vars = "who cares";
}
[Test]
public virtual void ShouldGenerateReport()
{
DataSet dataSetToReturn = new DataSet();
using (_mocks.Ordered())
{
Expect.Call(() => _myClass.ValidateWorkingDirectory());
Expect.Call(_myClassDataProvider.GetData(vars)).Return(dataSetToReturn);
Expect.Call(() => _myClass.InsertData(dataSetToReturn, "ReportName"));
}
_mocks.ReplayAll();
_myClass.GenerateReport(vars);
_mocks.VerifyAll();
}
}
将InsertData从内部更改为公共将解决此问题。我假设Rhino mock需要公开一个方法才能模拟出方法调用。
关于在预期之后添加IgnoreArguments,我不太确定它是如何通过的,因为当我尝试运行此代码时,它仍然调用了original方法。
希望这能帮助
