Question

我需要在抽象类中测试CheckWarehouseAvailability私有方法。

public abstract class BaseAPI
{
    private void CheckWarehouseAvailability(Order order)
    {
        //codes here
    }
}

public class Processor : BaseAPI
{

}

这是我的TestMethod

Processor pro = new Processor();
PrivateObject privBase = new PrivateObject(pro, new PrivateType(typeof(BaseAPI)));
var retVal = privBase.Invoke("CheckWarehouseAvailability(order)");
Assert.AreEqual(true, retVal);

当我运行测试方法时，我收到此错误：An exception of type 'System.MissingMethodException' occured in mscorlib.dll but was not handled in user code

Answer 1

您需要实例化Order的{{1}}参数并将其作为参数传递给CheckWarehouseAvailability：

PrivateObject.Invoke()

MSDN：PrivateObject.Invoke(String, Object[])

另外，我不确定你在这里断言：

var order = new Order(); 
var retVal = privBase.Invoke("CheckWarehouseAvailability", order);
// ... Assert

...因为Assert.AreEqual(true, retVal);将其返回类型设置为CheckWarehouseAvailability，而不是void。

Answer 2

首先，您需要通过反射获取方法

MethodInfo methodName = privBase.GetType().GetMethod("ShowGrid",
           BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);

然后用你的参数调用方法

var retVal=methodName .Invoke(privBase, order);
