Question

我正在构建一个Neo4j（2.2.3）非托管扩展并尝试运行集成测试。按照文档中的示例，我有：

@Test
public void testInsertInitiative() throws Exception { 
    try ( ServerControls server = TestServerBuilders.newInProcessBuilder()
        .withExtension("/graph/initiative", InitiativeController.class)
        .withFixture(TestFixtures.foobar(x, y, z))
        .newServer() )
    {
        HTTP.Response response = //... I can't get this far... 
    }
}

但是，每当我包含数据夹具时，测试都无法在a：

上初始化

java.io.EOFException: No content to map to Object due to end of input
at org.neo4j.harness.internal.Fixtures.ensureInstallSuccessful(Fixtures.java:127)
at org.neo4j.harness.internal.Fixtures.applyTo(Fixtures.java:110)
at org.neo4j.harness.internal.InProcessServerBuilder.newServer(InProcessServerBuilder.java:75)
at org.mycompany.myproject.MyTestClass.myTest(MyTestClass.java:87)

如果我注释掉夹具的包含，测试会按预期运行，所以问题肯定存在（也可以从堆栈跟踪中推断出来......）。我已经验证了我的TestFixtures方法通过c / p生成一个有效的cypher语句，并将其导入控制台并成功执行。我也尝试用简单的

替换它

.withFixture("CREATE (:foo)")

并得到了相同的结果。

版本2.2.3和2.2.2都会发生这种情况，无论是否加载我的扩展名都会发生这种情况。

在调试跟踪几层之后，我发现/harness/internal/Fixtures.java第109行的ClientResponse response = client.handle( req )调用收到的响应状态为Server Error和一个空实体，我认为这导致了EOF ......

但为什么服务器出错？再一次，我从客户端的呼叫中获取有效负载并将其（成功）发布到非测试服务器。

摆脱这种依赖关系将使测试在你的SSCCE中传递：

    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>javax.ws.rs-api</artifactId>
        <version>2.0</version>
        <scope>provided</scope>
    </dependency>

使用数据夹具时，Neo4j集成测试在EOFException上失败
