google-app-engine - 将 GAE 本地测试与 Objectify 结合使用

Question

我正在尝试使用 google app engine 提供的本地测试助手来对我使用 objectify 的应用程序进行单元测试。但是，一些测试失败并显示以下消息；

com.google.apphosting.api.ApiProxy$CallNotFoundException: The API package 'datastore_v3' or call 'Put()' was not found.
        at com.google.apphosting.api.ApiProxy$1.get(ApiProxy.java:164)
        at com.google.apphosting.api.ApiProxy$1.get(ApiProxy.java:162)

        at com.googlecode.objectify.util.ResultWrapper.translate(ResultWrapper.java:1)
        at com.googlecode.objectify.util.ResultTranslator.nowUncached(ResultTranslator.java:21)
        at com.googlecode.objectify.util.ResultCache.now(ResultCache.java:27)
        at com.googlecode.objectify.util.ResultWrapper.translate(ResultWrapper.java:20)
        at com.googlecode.objectify.util.ResultWrapper.translate(ResultWrapper.java:1)

        at com.googlecode.objectify.util.ResultCache.now(ResultCache.java:27)

这是我的代码:

private final LocalServiceTestHelper helper = new LocalServiceTestHelper(
    new LocalDatastoreServiceTestConfig(),
    new LocalMemcacheServiceTestConfig());

@BeforeMethod(alwaysRun = true)
public void setUp() {
    helper.setUp();
}

.....
//In class constructor
ObjectifyService.register(SomeClass.class);
.....
@AfterMethod(alwaysRun = true)
public void tearDown() {
    helper.tearDown();
}

public void doTest {
    SomeClass value = ......
    ofy().save().entity(value).now(); //throws error
}

这是我的依赖关系树:

知道我遗漏了什么或做错了什么吗？

我只是重现了这个错误并通过添加以下依赖项修复了它:

    <!--
      GAE libraries for local testing as described here:
      http://code.google.com/appengine/docs/java/howto/unittesting.html
    -->
    <dependency>
        <groupId>com.google.appengine</groupId>
        <artifactId>appengine-api-labs</artifactId>
        <version>${gae.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>com.google.appengine</groupId>
        <artifactId>appengine-api-stubs</artifactId>
        <version>${gae.version}</version>
        <scope>test</scope>
    </dependency>

我使用本地 maven 属性来引用相同的 gae 版本。
希望这有帮助
