如何对发送 SOAP Web 服务请求的代码进行单元测试？

发布于 2024-09-18 18:17:18 字数 384 浏览 3 评论 0原文

我想为一些代码编写一个单元测试，生成带有附件的 SOAP 消息并发送它：

SOAPConnectionFactory factory = SOAPConnectionFactory.newInstance();
conn = factory.createConnection();
conn.call(message, endpoint);

其中工厂是 javax.xml.soap.SOAPConnectionFactory

我不关心任何响应返回，但我希望能够验证发送的消息。代码将被重构，我想确保它之后发送与以前相同的消息。

是否有一个框架可以用来创建模拟端点，让我可以在测试中分析请求？如果是这样，一些示例代码将非常有用。

I want to write a unit test for some code that generates a SOAP message with an attachment and sends it:

SOAPConnectionFactory factory = SOAPConnectionFactory.newInstance();
conn = factory.createConnection();
conn.call(message, endpoint);

where the factory is a javax.xml.soap.SOAPConnectionFactory

I don't care about any response coming back but I want to be able to verify the message that gets sent. The code is going to be refactored and I want to make sure it sends that same messages afterwards as before.

Is there a framework i can use to create a mock endpoint that will let me analyse the request in my test? If so, some sample code would be very useful.

有一个名为 WSUnit 的 java.net 项目应该会有所帮助。它基本上是一个侦听消息的侦听器 servlet。您可以向其发送消息并使用 XMLUnit 验证消息的内容。

使用 JMock。 JMock 允许您测试行为而不是状态更改。为此，您需要将 SOAPCOnnectionFactory.newInstance() 方法封装在不同的对象中：

public class MySOAPConnectionFactory {

    public SOAPConnectionFactory getConnection() {
        return SOAPConnectionFactory.newInstance();
}

在代码中使用新类的对象。

conn = mySOAPConnectionFactory.getConnection();
conn.call( message, endpoint );

然后，在您的测试中，用模拟对象替换工厂，它将返回模拟连接。对模拟连接设置期望，以期待您正在寻找的呼叫。

final SOAPConnectionFactory mockConnection = mockery.mock(SOAPConnectionFactory.class);
final SOAPConnection mockSoapConnection = mockery.mock(SOAPConnection.class);
foo.setMySOAPConnectionFactory( mockConnectionFactory );
try {
        mockery.checking( new Expectations() {

        {
            atLeast( 1 ).of( mockConnectionFactory ).getConnection();
            will( returnValue( mockSoapConnection ) );
            atLeast( 1 ).of( mockConnection ).call(SOME_MESSAGE, ENDPOINT);
        }
        } );

Use JMock. JMock allows you to test for behavior rather than state changes. To do this, you'll need to encapsulate the SOAPCOnnectionFactory.newInstance() method in a diffent object:

public class MySOAPConnectionFactory {

    public SOAPConnectionFactory getConnection() {
        return SOAPConnectionFactory.newInstance();
}

Use an object of the new class in your code.

conn = mySOAPConnectionFactory.getConnection();
conn.call( message, endpoint );

Then, in your test, substitute a Mock object for the Factory, which will return a Mock Connection. Set expectations on the Mock Connection expecting the call you're looking for.

final SOAPConnectionFactory mockConnection = mockery.mock(SOAPConnectionFactory.class);
final SOAPConnection mockSoapConnection = mockery.mock(SOAPConnection.class);
foo.setMySOAPConnectionFactory( mockConnectionFactory );
try {
        mockery.checking( new Expectations() {

        {
            atLeast( 1 ).of( mockConnectionFactory ).getConnection();
            will( returnValue( mockSoapConnection ) );
            atLeast( 1 ).of( mockConnection ).call(SOME_MESSAGE, ENDPOINT);
        }
        } );
