c# - C#中的单元测试工厂类

Question

我有需要使用用户名密码进行身份验证的第三方 api 包装器类，所以我将初始化设置放在 Factory 类中，例如

public class ApiClientFactory
{
    private ApiClient apiClient;


    publi ApiClient GetApiClient()
    {
        try
        {
            String apiURL = ConfigurationManager.AppSettings["API_URL"];
            apiClient = new ApiClient(apiURL);

            // Auth to the API to get our JWT token for subsequent requests.
            AuthResponse response = apiClient.Authenticate(new AuthRequest()
            {
                Type = UserType.Staff,
                Username = ConfigurationManager.AppSettings["API_UserName"],
                Password = ConfigurationManager.AppSettings["API_Password"]
            });

            if (response != null)
            {
                //save the token for all subsequent requests
                apiClient.JwtToken = response.Token;
                response = null;
            }
            else
            {
                log.Error("APIClient Could not authenticate.");
            }

            return apiClient;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
}

public static void Main()
{
    try
    {
        ApiClientFactory clientFactory = new ApiClientFactory();
        apiClient = clientFactory.GetApiClient();

    }
    catch (Exception ex)
    {
        log.Error(ex.Message);
        return;
    }

    // use apiClient to call api method 

}

如何对 ApiClientFactory 类的 GetApiClient 进行单元测试。

由于工厂直接实例化了一个ApiClient，所以你无法用模拟替换ApiClient，所以你不能在没有实际发出请求的情况下测试工厂到服务器。您的工厂不应该执行身份验证，它应该只创建对象并返回它。
