如何解决“您尚未开始Objectify上下文”在JUnit中？

Jeff Schnitzer在这里回答了这个问题： groups.google/forum /＃！话题/客观化-的AppEngine / 8HinahG7irg 。该链接指向 groups.google/forum/# ！topic / objectify-appengine / O4FHC_i7EGk Jeff在其中建议了以下快速和肮脏的解决方法：

• My @BeforeMethod开始一个客观化上下文（ObjectifyService.begin（））

• My @AfterMethod关闭客观化上下文

Jeff建议我们使用 ObjectifyService.run（）代替它，但承认它有更多的工作。

下面是我的实现的样子：

public class DownloadTaskRepositoryImplTest { //最大一致性（请参阅cloud.google/appengine/docs/java/tools/localunittesting） private final LocalServiceTestHelper helper = $ b $ new LocalServiceTestHelper（new LocalDatastoreServiceTestConfig（） .setDefaultHighRepJobPolicyUnappliedJobPercentage（1 00））; 私密可关闭; @Before public void setUp（）{ helper.setUp（）; ObjectifyRegistrar.registerDataModel（）; closeable = ObjectifyService.begin（）; } @ 之后public void tearDown（）{ closeable.close（）; helper.tearDown（）; }

I've got some Objectify test code running in JUnit and I'm getting this error:

java.lang.IllegalStateException: You have not started an Objectify context. You are probably missing the ObjectifyFilter. If you are not running in the context of an http request, see the ObjectifyService.run() method. at com.googlecode.objectify.ObjectifyService.ofy(ObjectifyService.java:44) at com.googlecode.objectify.impl.ref.LiveRef.<init>(LiveRef.java:31) at com.googlecode.objectify.Ref.create(Ref.java:26) at com.googlecode.objectify.Ref.create(Ref.java:32) at combase.followerdownloader.repository.DownloadTaskRepositoryImpl.create(DownloadTaskRepositoryImpl.java:35) at combase.followerdownloader.repository.DownloadTaskRepositoryImplTest.setUp(DownloadTaskRepositoryImplTest.java:45)

How do I resolve this for test code?

Jeff Schnitzer answered this here: groups.google/forum/#!topic/objectify-appengine/8HinahG7irg. That link points to groups.google/forum/#!topic/objectify-appengine/O4FHC_i7EGk where Jeff suggests the following quick and dirty workaround:

• My @BeforeMethod starts an objectify context (ObjectifyService.begin())

• My @AfterMethod closes the objectify context

Jeff suggests we use ObjectifyService.run() instead but admits it's more work.

Here's how my implementation looks:

public class DownloadTaskRepositoryImplTest { // maximum eventual consistency (see cloud.google/appengine/docs/java/tools/localunittesting) private final LocalServiceTestHelper helper = new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig() .setDefaultHighRepJobPolicyUnappliedJobPercentage(100)); private Closeable closeable; @Before public void setUp() { helper.setUp(); ObjectifyRegistrar.registerDataModel(); closeable = ObjectifyService.begin(); } @After public void tearDown() { closeable.close(); helper.tearDown(); }
