测试布局：
Citrus -> SUT
SUT <-> MockServerOne
SUT <-> MockServerTwo
Citrus <- SUT
应用上面帖子中的建议，我现在看到随机发生的异常。
测试代码：
@Test
@CitrusTest
public void testRequestNok() throws Exception {
setDefaultTestVariables();
http(builder -> builder
.client("fooClient")
.send()
.post("/foo/bar")
.payload(new ClassPathResource("foo/foo-sample-request.xml"))
.messageType(MessageType.XML)
.contentType("application/xml")
.accept("application/xml")
.fork(true));
applyBehavior(new MockOneServerBehavior());
applyBehavior(new MockTwoServerBehavior("bar/bar-error-response.xml"));
http(builder -> builder.client("fooClient").receive().response(HttpStatus.BAD_GATEWAY));
}
行为看起来像这样
public class MockOneServerBehavior extends AbstractTestBehavior {
public void apply() {
http(builder -> builder.server("mockServerOne")
.receive()
.post());
http(builder -> builder.server("mockServerOne")
.send()
.response()
.payload(new ClasspathResource("foo/bar.xml"));
}
}
测试失败（大约占所有情况的 5%），到目前为止，我已经看到了两种不同的异常：
一个ConcurrentModificationException：

在XMLParseException的情况下，我已经在 HTTP 级别验证了响应与测试实际通过时的响应相同。
这两个例外对我来说都像是线程问题。
对于我可能尝试的任何反馈或替代方法，我将不胜感激。
