Я пытался следовать этому как руководство для проверки реестра: http://www.rhyous.com/2011/11/04/unit-testing-registry-access-with-rhinomocks-and-systemwrapper/
Когда я пытаюсь смоделировать это, я всегда получаю нулевое возвращение для "reg" в моем классе, когда он пытается выполнить вызов OpenSubKey, в моем тесте _Real () он работает нормально.
Тесты:
private RegistryService CreateMockedRegistryService()
{
var registryService = new RegistryService(MockRepository.GenerateMock<ILoggerFacadeExtended>(), MockRepository.GenerateMock<IConnectivityService>());
// Mock the Base Key so we can throw errors and manipulate it
registryService.ChangeBaseKey(MockRepository.GenerateMock<IRegistryKey>());
return registryService;
}
private IRegistryKey CreateMockedHKLM()
{
IRegistryKey hklmMock = MockRepository.GenerateMock<IRegistryKey>();
hklmMock.Stub(x => x.Name).Return("HKEY_LOCAL_MACHINE");
return hklmMock;
}
[TestMethod()]
public void GetRegistryKeyTest_Mocked()
{
IRegistryService target = CreateMockedRegistryService();
string machineName = "localhost";
RegistryHive hive = RegistryHive.LocalMachine;
string path = @"SOFTWARE\Microsoft\Windows NT\CurrentVersion";
string valueName = "SystemRoot";
object defaultValue = @"C:\Windows";
IRegistryKey keyMock = CreateMockedHKLM();
keyMock.Stub(x => x.OpenRemoteBaseKey(hive, machineName)).Return(CreateMockedHKLM());
var subKeyMock = MockRepository.GenerateMock<IRegistryKey>();
subKeyMock.Stub(x => x.Name).Return(keyMock.Name + @"\" + path);
subKeyMock.Stub(x => x.GetValueNames()).Return(new string[] { valueName });
subKeyMock.Stub(x => x.GetValue(valueName)).Return(defaultValue);
keyMock.Stub(x => x.OpenSubKey(path)).Return(subKeyMock);
keyMock.Stub(x => x.GetValue(valueName)).Return(defaultValue);
target.ChangeBaseKey(keyMock);
IResult<object> expected = new Result<object>() { Results = defaultValue };
IResult<object> actual;
actual = target.GetRegistryKey(machineName, hive, path, valueName, defaultValue);
Assert.AreEqual(expected.Results, actual.Results);
}
[TestMethod()]
public void GetRegistryKeyTest_Real()
{
IRegistryService target = CreateMockedRegistryService();
string machineName = "localhost";
RegistryHive hive = RegistryHive.LocalMachine;
string path = @"SOFTWARE\Microsoft\Windows NT\CurrentVersion";
string valueName = "SystemRoot";
object defaultValue = @"C:\Windows";
// We don't want to use the regular Mocked version but actually hit the registry so it works
IRegistryKey baseKey = new RegistryWrap().LocalMachine;
target.ChangeBaseKey(baseKey);
IResult<object> expected = new Result<object>() { Results = defaultValue };
IResult<object> actual;
actual = target.GetRegistryKey(machineName, hive, path, valueName, defaultValue);
Assert.AreEqual(expected.Results, actual.Results);
}
Фактический класс:
private IRegistryKey _BaseKey;
public IRegistryKey BaseKey
{
get
{
if (_BaseKey == null)
{
_BaseKey = new RegistryWrap().LocalMachine;
}
return _BaseKey;
}
}
public void ChangeBaseKey(IRegistryKey inBaseKey)
{
_BaseKey = inBaseKey;
}
public IResult<object> GetRegistryKey(string machineName, RegistryHive hive, string path, string valueName, object defaultValue)
{
return GetRegistryKey(BaseKey.OpenRemoteBaseKey(hive, machineName), path, valueName, defaultValue);
}
}
public IResult<object> GetRegistryKey(IRegistryKey baseKey, string path, string valueName, object defaultValue)
{
IResult<object> result = new Result<object>();
try
{
if (baseKey == null) throw new ArgumentNullException("baseKey");
if (string.IsNullOrWhiteSpace(path)) throw new ArgumentException("path");
if (string.IsNullOrWhiteSpace(valueName)) throw new ArgumentException("valueName");
var reg = baseKey.OpenSubKey(path);
result.Results = reg.GetValue(valueName); // reg is null when I try to Mock it
.....
}
