Question

我一直在使用 ElasticsearchIntegrationTest 来测试我的代码而不使用elasticsearch服务器。我班上的私人会员很少，所以想到使用 Powermock 来访问私人会员。在运行测试时我得到例外。

Powermock可以与ElasticsearchIntegrationTest一起使用吗？

代码：

import org.elasticsearch.test.ElasticsearchIntegrationTest;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;


@RunWith(PowerMockRunner.class)
@PrepareForTest(AbstractTest.class)
public class PowerMockitTest extends ElasticsearchIntegrationTest{

    AbstractTest abstractTest =  mock(AbstractTest.class);

    @Test
    public void testPowerMokito() throws Exception{
      doReturn(internalCluster().transportClient()).when(abstractImporter, "initClient");
    }

}

例外：

Answer 1

Base on your stack trace I can guess that either org.elasticsearch.test.ElasticsearchIntegrationTest or one of superclass or field depends on org.apache.http.impl.client.CloseableHttpClient and the class cannot be found in Runtime, so it means class not in test class path.
