我在使用PrepareForTest注释和创建 AmazonSQSClient 的新实例时遇到了一些问题。

我正在编写一个 Jenkins 插件，不幸的是需要模拟FormValidation静态类，以确保在我的插件的字段验证时产生警告和错误消息。但是，当创建一个实例时，AmazonSQSClient我得到一个org.apache.http.conn.ssl.SSLInitializationException

我将其抽象为一个非常简单的示例，这是我的测试文件：

package com.test;

import com.amazonaws.services.sqs.AmazonSQS;
import com.amazonaws.services.sqs.AmazonSQSClient;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)  
public class SQSTest {

    // This is for mimicking the mocking of FormValidation
    private static class Foo {}

    @Test
    @PrepareForTest(Foo.class)
    public void buildTest()
    {
        AmazonSQS sqs = new AmazonSQSClient();
    }
}

在运行此代码时，我收到以下错误：

从方法中删除注释@PrepareForTest(Foo.class)后，测试运行良好。

我想知道是否有人可以解释为什么会发生这种情况以及是否有解决方法或避免嘲笑FormValidation课堂的方法？

谢谢。

尝试@PowerMockIgnore("org.apache.http.conn.ssl.*")为您的课程添加注释

正如@Natalie 已经提到的，您可以使用@PowerMockIgnore()注释。也许您需要忽略包javax.net.ssl.*和/或javax.crypto.*：

@PowerMockIgnore({"org.apache.http.conn.ssl.*", "javax.net.ssl.*" , "javax.crypto.*"})

你可以在这里获得一些背景信息：

这很可能是因为 SSLContext 是由引导类加载器加载的，而 PowerMock 无法对这些类进行字节码操作。您必须使用这种方法来模拟该方法。/约翰·黑尔比
