测试Mule中的子流程 [英] Testing sub-flows in Mule

问题描述

我已经开始将测试用例写入我的Mule项目了。

I have started writing test cases to my Mule project.

我已经为我的主要流程编写了功能测试用例，如下所示。

I have written the functional test case for my Main Flows as follows.

public void testMainFlow_1() throws Exception{
     MuleClient client = muleContext.getClient();
            MuleMessage result = client.send(helloServiceAddress, fileAsString("SamplePayloads/input_Request.xml"), properties);
    assertNotNull("Null Result", result);           
    assertEquals(result.getPayloadAsString(), fileAsString("SampleResponses/sampleResponse.xml"));   

}

但我如何测试我的子流程。他们没有任何终点。那么我怎样才能将有效载荷传递给它们并对其进行测试。

But how can I test my sub-flows. They don't have any end-points. So how can I pass payload to them and test it.

以下是我的流量配置。

<flow name="main_flow" >
    ....
    ....
    <flow-ref  name="subflow_1" />
    ....
    ....
    <flow-ref  name="subflow_2" />
    ....
    ....
</flow>

<sub-flow name="subflow_1">
    ....
    <some-transformer ... />
    <out-bound call to web-service />
    <some-transformer ... />
    ....
</sub-flow>

<sub-flow name="subflow_2">
    ....
    <some-transformer ... />
    <out-bound call to web-service />
    <some-transformer ... />
    ....
</sub-flow>

推荐答案

使用 FunctionalTestCase 它应该简单如下：

MessageProcessor subFlow = muleContext.getRegistry().lookupObject("subflow_1");
MuleEvent result = subFlow.process(getTestEvent("test_data"));

但它不起作用。

目前，最好的方法是IMO包含一个包含流的测试配置要测试的子流的包装器，并在 FunctionalTestCase 中将主测试配置与此测试配置一起加载。

For now, the best approach IMO consists in having a test config that contains flow wrappers for the sub-flows you want to test and load this test config alongside your main config in the FunctionalTestCase.

@ genjosanzo的方法也有效，但它基于将子流与来自测试代码本身的预先存在的主流相关联。我个人认为创建测试流程会更严格。

@genjosanzo's approach works too but it is based on associating the sub-flow with a pre-existing main-flow from test code itself. I personally think it would be stricter to create test flows instead.
