前提是使用 Idea 进行单框架的集成,其他工具没有尝试过.
问题来源
在参考 Elasticsearch 官方单元测试集成方式的时候,在编写自己的单元测试的时候,出现了让人郁闷的异常,这里我的单元测试是创建一个名称为"test-index"的索引,代码如下:
public class SampleTest extends ESIntegTestCase {
@Test
public void test() throws Exception {
createIndex("test-index");
assertTrue(indexExists("test-index"));
}
}
运行单元测试,出现以下异常:
java.lang.RuntimeException: found jar hell in test classpath

Add @RunWith(class com.carrotsearch.randomizedtesting.RandomizedRunner.class) to your test class. Make sure your code accesses random contexts within @BeforeClass and @AfterClass boundary (for example, static test class initializers are not permitted to access random contexts).

我们看下一共出现了哪些异常,见下面的 ##问题和解决方法##
问题和解决方法
问题 1
- ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
解决方式：
在 pom.xml 文件添加 log4j-core 的依赖 jar 包,参考如下:
<dependency>
<groupId>org.apache.logging.log4jgroupId>
<artifactId>log4j-coreartifactId>
<version>2.8.2version>
dependency>
问题 2
- found jar hell in test classpath
解决方式:
-
在你的测试代码目录下创建一个包:org.elasticsearch.bootstrap
-
在 org.elasticsearch.bootstrap 包下创建 JarHell 类,源码如下:
package org.elasticsearch.bootstrap; import java.net.URL; /** * @auhthor lei.fang@shijue.me * @since . 2017-11-24 */public class JarHell { private JarHell() {} public static void checkJarHell() throws Exception {} public static void checkJarHell(URL urls[]) throws Exception {} public static void checkVersionFormat(String targetVersion) {} public static void checkJavaVersion(String resource, String targetVersion) {} public static URL[] parseClassPath() {return new URL[]{};} } -
添加 VM options 参数 -ea -Dtests.security.manager=false
这样就能自己编写单元测试来测试 Elasticsearch 和 Lucene 的相关功能,整个 pom.xml 如下
<dependencies>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-test-framework</artifactId>
<version>7.0.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.elasticsearch.test</groupId>
<artifactId>framework</artifactId>
<version>6.0.0</version>
<scope>test</scope>
<dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.8.2</version>
</dependency>
<dependencies>
重新运行单元测试,测试结果如下:
