如何從JUnit啓動Google App Engine Java開發服務器？

Question

我想編寫針對本地開發Web服務器運行的自動化測試。對底層服務編寫測試非常簡單（https://cloud.google.com/appengine/docs/java/tools/localunittesting），但我想測試我的完整堆棧。我可以使用Runtime.exec（）啓動並殺死服務器，但我希望有人開發出更優雅的解決方案。

我找到了答案the Javadocs。使用DevAppServerTestRunner：

@RunWith(DevAppServerTestRunner.class) 
@DevAppServerTest(EndToEndTest.TestConfig.class) 
public class EndToEndTest { 

    private final LocalServiceTestHelper testHelper = new LocalServiceTestHelper(
    new LocalURLFetchServiceTestConfig(), new LocalDatastoreServiceTestConfig()); 

    public static class TestConfig extends BaseDevAppServerTestConfig { 

    public File getSdkRoot() { 
     return new File(...); 
    } 

    public File getAppDir() { 
     return new File(...); 
    } 

    public List<URL> getClasspath() { 
     return Arrays.asList(...); 
    } 
    } 

    @Before 
    public void setUpHelper() { 
    testHelper.setUp(); 
    } 

    @After 
    public void tearDownHelper() { 
    testHelper.tearDown(); 
    } 

    @Test 
    public void testEndToEnd() throws Exception { 
    URLFetchService fetchService = URLFetchServiceFactory.getURLFetchService(); 
    HTTPResponse resp = fetchService.fetch(new URL("http://localhost:8080/insertFoo?id=33")); 
    Assert.assertEquals(200, resp.getResponseCode()); 
    DatastoreServiceFactory.getDatastoreService().get(KeyFactory.createKey("foo", 33)); 
    } 
}
