Google App Engine:在 JUnit 测试用例中使用 TaskQueue 时出现异常

问题描述 投票:0回答:2

我想从 Junit 测试用例中调用任务队列。我的代码是:

@Test
    public void monthlyCronTest1() throws Exception {
....
       Queue queue = QueueFactory.getQueue("updateVcoCron");
       TaskOptions options = TaskOptions.Builder.withUrl(String.format("/api/v1/users/update/validation/points")).method(TaskOptions.Method.GET);
                    options.param("pageNumber", String.valueOf(pageNumber));
                    options.param("validatableBrands", validatableBrands);
          queue.add(options); // this line throw exception
......
}

这里我收到错误:

 Exception:java.lang.IllegalStateException: The specified queue is unknown : updateVcoCron
    [junit] 1577867 INFO  org.quartz.impl.StdSchedulerFactory  - Quartz scheduler 'DefaultQuartzScheduler' initialized f
rom default resource file in Quartz package: 'quartz.properties'
    [junit] 1577867 INFO  org.quartz.impl.StdSchedulerFactory  - Quartz scheduler version: UNKNOWN.UNKNOWN.UNKNOWN
    [junit] 1577867 INFO  org.quartz.core.QuartzScheduler  - Scheduler DefaultQuartzScheduler_$_NON_CLUSTERED started.

2)如果我使用默认队列,例如:

   Queue queue = QueueFactory.getDefaultQueue();

我得到了不同的错误。

    [junit] com.google.apphosting.api.ApiProxy$ApplicationException: ApplicationError: 2: Received exception executing h

exception.

我的queue.xml位于以下路径中:

src/main/webapp/WEB-INF。

现在我的问题是:JUnit 环境还有配置吗?为什么它不选择queue.xml?请在这里帮忙。

java google-app-engine junit task-queue

我遇到了“指定的队列未知”错误。查看此解决方案后https://stackoverflow.com/a/11200214/2742117,我通过将其添加到我的基本测试类来修复它

private static String dir;
static {
  dir = System.getProperty("user.dir") + "/src/main/webapp/WEB-INF/queue.xml";
  System.out.println(dir);
}

protected final LocalServiceTestHelper helper =
  new LocalServiceTestHelper(
      //some other configurations removed for brevity...
      new LocalTaskQueueTestConfig().setQueueXmlPath(dir)
  );

此后,我的测试能够使用我的非默认队列。

我不是在单元测试中遇到这个问题,而是在现实中遇到这个问题。最后我必须在我的queue.xml中实际添加新队列

<queue>
    <name>myNewQueue</name>
    <rate>100/s</rate>
    <max-concurrent-requests>100</max-concurrent-requests>
    <retry-parameters>
        <task-age-limit>300h</task-age-limit>
        <min-backoff-seconds>10</min-backoff-seconds>
        <max-backoff-seconds>200</max-backoff-seconds>
        <max-doublings>0</max-doublings>
    </retry-parameters>
    <target>my-queue-service</target>
</queue>
