[英]Mock Apache Camel out location in JUnit testing
我試圖嘲弄in
和out
駱駝路線的路徑,但我不知道如何進出path.Please幫我解決this.Thanks提前提供模擬。
application.properties
inputFilePath = src/main/resources/in
outputFilePath = src/main/resources/out
application-test.properties
inputFilePath = src/test/java/in
outputFilePath = src/test/java/out
路由器和處理器:
@Component
public class FileLineByLineRouter extends RouteBuilder {
@Value("${inputFilePath}")
private String inputFilePath;
@Value("${outputFilePath}")
private String outputFilePath;
@Override
public void configure() throws Exception {
from("file://" + inputFilePath + "?delete=true").routeId("FileLineByLineRoute").marshal().string("UTF-8")
.split(body().tokenize("\n")).streaming().process(getFileParsingProcessor())
.to("file://" + outputFilePath + "?fileExist=Append").end();
}
@Bean
public Processor getFileParsingProcessor() {
return new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
String order = exchange.getIn().getBody(String.class);
order = order + ": " + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss S").format(new Date()) + "\n";
exchange.getIn().setBody(order);
}
};
}
}
Junit測試代碼:
@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class })
@SpringBootTest(classes = FileLineByLineRouter.class)
@ActiveProfiles("test")
@EnableAutoConfiguration
public class FileLineByLineRouterTest2 extends CamelTestSupport {
@Autowired
protected CamelContext camelContext;
@Test
public void test() throws Exception {
camelContext.start();
Thread.sleep(2000);
File outDir = new File("src/test/java/out");
System.out.println(outDir.getAbsolutePath());
assertTrue(outDir.isDirectory());
assertTrue(outDir.listFiles().length != 0);
}
}

似乎您將Camel與Spring結合使用。 我在這里使用的一般設置通常是下面的內容,下面我將對其進行評論以解釋所使用的概念有什么用處。
請注意,我還添加了一個作為Spring bean公開的通用服務,該服務實際上定義為Mockito模擬,以展示如何在測試中利用此類模擬。
// These 2 annotation allow the injection of Spring beans into this test class as
// well, ideally if you want to mock certain services defined as Spring bean
// with i.e. Mockito
@RunWith(CamelSpringRunner.class)
@BootstrapWith(CamelTestContextBootstrapper.class)
// we are going to slightly modify the route to test in order to simplify
// things a bit, hence we use @UseAdviceWith
@UseAdviceWith
@ContextConfiguration(loader = AnnotationConfigContextLoader.class,
classes = { FileLineByLineRouterTest2.ContextConfig.class })
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
public class FileLineByLineRouterTest2 {
// Spring bean setup needed to setup the beans required while testing your route
@Configuration
@PropertySource({"classpath:application-test.properties"})
public static class ContextConfig extends CamelConfiguration {
@Override
public List<RouteBuilder> routes() {
final List<RouteBuilder> routes = new ArrayList<>();
routes.add(routeToTest());
return routes;
}
// This bean is required to access the property files using @Value("${...}")
@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
@Bean
public FileLineByLineRouter routeToTest() {
return new FileLineByLineRouter();
}
@Bean
public SomeService mockService() {
return mock(SomeService.class);
}
}
@Autowired
private CamelContext camelContext;
@Autowired
private ProducerTemplate template;
@Autowired
private SomeService someService;
// @MockEndpoints("mock:result")
// private MockEndpoint resultEndpoint
@Test
public void test() throws Exception {
// ARRANGE
// modify the route to test to simplify testing
camelContext.getRouteDefinition("FileLineByLineRoute")
.adviceWith((ModelCamelContext) camelContext,
new AdviceWithRouteBuilder() {
@Override
public void configure() throws Exception {
// replace the file endpoint used in the from RouteBuilder
// method with a direct endpoint for easier testing
this.replaceFromWith("direct:start");
// redirect the output which should be written to a file
// to a mock endpoint
this.interceptSendToEndpoint("file:*")
.skipSendToOriginalEndpoint()
.to("mock:result");
}
});
// create a mock endpoint to redirect output and define some basic assertions
// on either the number of processed outputs or the format of the body
// received by that mock endpoint. You can also use the commented out
// annotation approach from above instead
// More information available at: http://camel.apache.org/mock.html
MockEndpoint resultEndpoint = camelContext.getEndpoint("mock:result", MockEndpoint.class);
resultEndpoint.expectedMessageCount(1);
// other assertions on the mock endpoint possible as well here
// define behavior of mocks
when(someService.doSomething()).thenReturn("something");
// ACT
// use the producer template to send a body (and headers) to the route
// to test. This can litteraly be anything. A byte array, a simple string,
// a complex object, ...
String testContent = "...";
template.sendBody("direct:start", testContent);
// ASSERT
// check that the mock endpoint has received the actual number of bodies specified
// before invoking the template above
resultEndpoint.assertIsSatisfied();
// retrieve the final body and/or headers from the processed exchanges
// and perform your assertion against them
List<Exchange> exchanges = resultEndpoint.getExchanges();
assertThat(exchanges.size(), is(equalTo(1));
Object retBody = exchanges.get(1).getOut().getBody();
assertThat(retBody, is(equalTo(...));
}
}
如果您確實希望在測試過程中保持文件使用者和生產者的身份,那么我將使用JUnits TemporaryFolder
規則,該規則看起來可能像這樣:
private MockEndpoint result;
@Rule
public TemporaryFolder sourceFolder = new TemporaryFolder();
@Before
public void init() throws Exception {
result = context.getEndpoint("mock:result", MockEndpoint.class);
context.getRouteDefinition("route-to-test")
.adviceWith((ModelCamelContext) context,
new AdviceWithRouteBuilder() {
@Override
public void configure() throws Exception {
replaceFromWith("file://" + sourceFolder.getRoot().toString()
+"?fileExist=Move"
+ "&moveExisting=${file:name.noext}-${date:now:yyyyMMddHHmmssSSS}.${file:ext}"
+ "&tempFileName=${file:name}.tmp");
interceptSendToEndpoint("file:*").skipSendToOriginalEndpoint().to(result);
}
});
writeFileContent("sample1.xml", "/filesystem/outbound/sample1.xml");
writeFileContent("sample2.xml", "/filesystem/outbound/sample2.xml");
writeFileContent("sample3.xml", "/filesystem/outbound/sample3.xml");
writeFileContent("sample4.xml", "/filesystem/outbound/sample4.xml");
context.start();
}
其中writeFileContent
簡單地將文件內容復制到用於測試的臨時文件夾中
private void writeFileContent(String name, String source) throws Exception {
File sample = sourceFolder.newFile(name);
byte[] bytes = IOUtils.toByteArray(getClass().getResourceAsStream(source));
FileUtils.writeByteArrayToFile(sample, bytes);
}
實際上,也可以將輸出寫入臨時測試目錄,而不用通過模擬端點對其進行處理。 然后,此方法類似於定義用於將文件發送到路由的臨時測試目錄。 因此,我將這種方法留給您。
好的,在重新閱讀您的評論和更新的問題之后,我想我現在已經明白了您的意思了……您的測試還無法進行。
嘗試這個:
extends CamelTestSupport
。 這是基於注釋的測試支持的替代方法。 camelContext.start()
。 我可能將我的建議示例弄糊塗了。 使用@UseAdviceWith
注釋類時,僅需要自己啟動上下文。 Thread.sleep(10000)
,以使文件有時間進行處理。 您可以使用Camel NotifyBuilder( http://camel.apache.org/notifybuilder.html )來代替固定睡眠。
您可以提取到application-dev.properties(或yml)的in
和out
路徑。
path.in=src/main/resources/in
path.out=src/main/resources/out
然后configure()
方法應更改為類似的內容
@Override
public void configure() throws Exception {
from("file://{{path.in}}?delete=true")
.routeId("FileLineByLineRoute")
.marshal().string("UTF-8")
.split(body().tokenize("\n")).streaming()
.process(getFileParsingProcessor())
.to("file://{{path.out}}?fileExist=Append")
.end();
}
然后在測試中,您可以模擬屬性,也可以加載其他屬性文件
我認為您可能會在這里找到答案: 示例FilterTest.java
這是相關的摘錄。
@Override
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
public void configure() {
from("direct:start").filter(header("foo").isEqualTo("bar"))
.to("mock:result");
}
};
}
