六、测试模式

1.1.0版本开始增加了apollo-mockserver，从而可以很好地支持单元测试时需要mock配置的场景，使用方法如下：

6.1 引入pom依赖

<dependency>
    <groupId>com.ctrip.framework.apollo</groupId>
    <artifactId>apollo-mockserver</artifactId>
    <version>1.1.0</version>
</dependency>

6.2 在test的resources下放置mock的数据

文件名格式约定为mockdata-{namespace}.properties

6.3 写测试类

更多使用demo可以参考ApolloMockServerApiTest.java和ApolloMockServerSpringIntegrationTest.java。

@RunWith(SpringJUnit4ClassRunner.class)@SpringApplicationConfiguration(classes = TestConfiguration.class)public class SpringIntegrationTest {  // 启动apollo的mockserver  @ClassRule  public static EmbeddedApollo embeddedApollo = new EmbeddedApollo();
  @Test  @DirtiesContext  // 这个注解很有必要，因为配置注入会弄脏应用上下文  public void testPropertyInject(){    assertEquals("value1", testBean.key1);    assertEquals("value2", testBean.key2);  }
  @Test  @DirtiesContext  public void testListenerTriggeredByAdd() throws InterruptedException, ExecutionException, TimeoutException {    String otherNamespace = "othernamespace";    embeddedApollo.addOrModifyPropery(otherNamespace,"someKey","someValue");    ConfigChangeEvent changeEvent = testBean.futureData.get(5000, TimeUnit.MILLISECONDS);    assertEquals(otherNamespace, changeEvent.getNamespace());    assertEquals("someValue", changeEvent.getChange("someKey").getNewValue());  }
  @EnableApolloConfig("application")  @Configuration  static class TestConfiguration{    @Bean    public TestBean testBean(){      return new TestBean();    }  }
  static class TestBean{    @Value("${key1:default}")    String key1;    @Value("${key2:default}")    String key2;
SettableFuture&lt;ConfigChangeEvent&gt; futureData = SettableFuture.create();
@ApolloConfigChangeListener(&#34;othernamespace&#34;)
private void onChange(ConfigChangeEvent changeEvent) {
  futureData.set(changeEvent);
}
  }}
