PowerMock PrepareForTest annotation causing problems with AmazonSQSClient constructor
提问by Sarah Tattersall
I'm having some trouble with the PrepareForTestannotation and creating a new instance of an AmazonSQSClient.
我在使用PrepareForTest注释和创建 AmazonSQSClient 的新实例时遇到了一些问题。
I'm writing a Jenkins plugin and unfortunately need to mock the FormValidationstatic class in order to ensure that warning and error messages are produced on field validation of my plugin. However when creating an instance of AmazonSQSClientI get an org.apache.http.conn.ssl.SSLInitializationException
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生成警告和错误消息。但是，当创建一个实例时，AmazonSQSClient我得到一个org.apache.http.conn.ssl.SSLInitializationException
I've abstracted it down to a very simple example, here's my test file:
我把它抽象成一个非常简单的例子，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();
}
}
On running this code I get the following error:
在运行此代码时，我收到以下错误：

When the annotation @PrepareForTest(Foo.class)is removed from the method the test runs fine.
@PrepareForTest(Foo.class)从方法中删除注释后，测试运行良好。
I was wondering if someone could explain why this is happening and if there is a work around for it or a way to avoid mocking the FormValidationclass?
我想知道是否有人可以解释为什么会发生这种情况，是否有解决方法或避免嘲笑FormValidation课程的方法？
Thanks.
谢谢。

Try to add @PowerMockIgnore("org.apache.http.conn.ssl.*")annotation to your class
尝试@PowerMockIgnore("org.apache.http.conn.ssl.*")为您的课程添加注释
回答by Marc
As @Natalie already mentioned, you can work with the @PowerMockIgnore()annotation. Maybe you need to ignore the packages javax.net.ssl.*and / or javax.crypto.*:
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.*"})

This is most likely because SSLContext is loaded by the bootstrap classloader and PowerMock cannot byte-code manipulate these classes. You have to use this approach to mock that method. /Johan Haleby
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·哈勒比
