我知道App Engine数据存储区查询最终只是一致的。但是,对于我的一些测试,我想用已经一致的数据为数据存储区播种(即它在测试发生之前保存了很长时间,现在全局一致)。
如何在运行测试之前确保初始数据是否一致?我仍然希望能够要求被测试的行动不需要立即保持一致。
我使用的是Google Cloud Endpoints for Java,但我并不是特定于端点的任何内容。

我最终创建了以下BaseTest类,并让我的所有测试继承自:
package com.example;
import com.google.appengine.api.datastore.Key;
import com.google.appengine.api.datastore.dev.HighRepJobPolicy;
import com.google.appengine.tools.development.testing.LocalDatastoreServiceTestConfig;
import com.google.appengine.tools.development.testing.LocalServiceTestHelper;
import org.junit.After;
import org.junit.Before;
import org.junit.Rule;
public class BaseTest {
public static final class Policy implements HighRepJobPolicy {
static boolean shouldApply = false;
public static void applyAll() {
shouldApply = true;
}
public static void applyNone() {
shouldApply = false;
}
@Override
public boolean shouldApplyNewJob(Key entityGroup) {
return shouldApply;
}
@Override
public boolean shouldRollForwardExistingJob(Key entityGroup) {
return shouldApply;
}
}
public final LocalServiceTestHelper helper =
new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig()
.setAlternateHighRepJobPolicyClass(Policy.class));
@Before
public void setUp() {
helper.setUp();
}
@After
public void tearDown() {
helper.tearDown();
}
}
然后测试可以采用以下形式:
@Test
public void thingShouldDoX() throws Exception {
Policy.applyAll();
// Do setup here, everything inside will be consistent.
Policy.applyNone();
// Run code under test here, without consistency.
}
