Question

我正在尝试为骡流编写集成测试，该测试从JMS队列中检索文件并将其插入到数据库中。当DB不可用时，一个测试场景正在运行异常流程（连接错误）。对于这个测试，我想模拟DB连接器并让它抛出异常。

我试图像这样模仿连接器：

@Test
public void testDBOutageException() throws Exception {
    MuleEvent event = testEvent(INPUT_VALID_XML);

    java.net.ConnectException connectException = new java.net.ConnectException("Could not connect to DB!");     
    MessageProcessorMocker dbMocker = whenMessageProcessor("insert").ofNamespace("db");     
    dbMocker.thenThrow(connectException);

    event = runFlow("thomson-reuters-processFlow", event);
}

当运行上面的测试用例时，将成功调用流，但不会模拟DB连接器。它只是调用DB并插入数据。这不是我想要实现的目标。

我的流程如下：

任何使这项工作成功的想法？

MUnit 1.1.0中有一个错误，其中DB Mock无法运行。它已在最近发布的MUnit 1.2.0版本中修复，尝试1.2.0。您使用的是什么版本的MUnit？

Munit模拟数据库连接器
