使用NUnit对动作进行单元测试

本文关键字:单元测试 NUnit 使用 | 更新日期: 2023-09-27 18:24:54

我想用NUnit和Rhino Mocks对以下函数进行单元测试。该函数使用给定的参数创建RestSharp.RestRequest并向dataAccessApi:发出请求

public void CopyToUserSession(string uri, string sourcePath)
{
    RestRequest request = new RestRequest(uri, Method.POST);
    request.AddParameter("source-path", sourcePath);
    dataAccessApi.Request<object>(request, restExecution.Get);
}

这是测试类别:

public void CopyToUserSession_ValidUriAndParameter_CallDataAccessRequest()
{
    // Arrange
    var dataAccessApi = MockRepository.GenerateMock<IDataAccessApi>();
    var restExecution = MockRepository.GenerateMock<IRestExecution>();
    var sinkNodeResource = new SinkNodeResource(dataAccessApi, restExecution);
    string uri = "http://SomeUri.com";
    string sourcePath = "Some Source Path";
    RestRequest request = new RestRequest(uri, Method.POST);
    request.AddParameter("source-path", sourcePath);
    // Act
    sinkNodeResource.CopyToUserSession(uri, sourcePath);
    // Assert
    dataAccessApi.AssertWasCalled(x => x.Request<object>(request, restExecution.Get));
}

IDataAccessApi…:

public interface IDataAccessApi
{
    void Request<T>(RestRequest request, Action<T> callbackAction) where T : new();
} 

以及IRestExecution:

public interface IRestExecution
{
    void Get(object o);
    void Put(object o);
    void Post(object o);
    void Delete(object o);
}

该测试使用了更容易调用的函数(如x.Test("Some String")),但不使用Action new RestExecution().Get——我如何对这些调用进行单元测试?

提前感谢您的帮助!

使用NUnit对动作进行单元测试

尝试以下操作:

// arrange
var dataAccessApi = MockRepository.GenerateMock<IDataAccessApi>();
var restExecution = MockRepository.GenerateMock<IRestExecution>();
var sinkNodeResource = new SinkNodeResource(dataAccessApi, restExecution);
string uri = "http://SomeUri.com";
string sourcePath = "Some Source Path";
// act
sinkNodeResource.CopyToUserSession(uri, sourcePath);
// assert
dataAccessApi.AssertWasCalled(
    x => x.Request<object>(
        Arg<RestRequest>.Matches(
            y => y.Method == Method.POST && 
                 y.Resource == uri &&
                 y.Parameters.Count == 1 &&
                 y.Parameters[0].Value as string == sourcePath
        ),
        Arg<Action<object>>.Is.Equal((Action<object>)restExecution.Get)
    )
);
