Java 将junit测试加载到不同的JVM
我从ApacheHBase项目中获得了名为Java 将junit测试加载到不同的JVM,java,unit-testing,maven,junit,Java,Unit Testing,Maven,Junit,我从ApacheHBase项目中获得了名为TestColumnPrefixFilter的junit测试用例。在这个测试用例中,有两个测试。当我使用命令行使用maven运行此测试用例时: mvn test -Dtest=org.apache.hadoop.hbase.filter.TestColumnPrefixFilter 我得到这个结果: Running org.apache.hadoop.hbase.filter.TestColumnPrefixFilter Tests run: 2, F
TestColumnPrefixFilter
的junit测试用例。在这个测试用例中,有两个测试。当我使用命令行使用maven运行此测试用例时:
mvn test -Dtest=org.apache.hadoop.hbase.filter.TestColumnPrefixFilter
我得到这个结果:
Running org.apache.hadoop.hbase.filter.TestColumnPrefixFilter
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 3.585 seconds
我的问题是,有没有办法在不修改代码的情况下从这个测试用例中分别运行这两个测试?maven或java是否可以选择这样做?或者可以在不同的JVM中运行这两个测试吗?因为当我调用上面的命令行时,这个测试用例被加载到一个jvm中,这个jvm用于我不想要的两个测试
我为maven尝试了perTest选项,但没有成功

是否可以在不同的JVM中运行这两个测试
是的,maven有一个选项,可以从文档中选择reuseForks
指示是否可以重用分叉的VM。如果设置为“false”,则为要执行的每个测试类分叉一个新VM。如果设置为“true”,则最多分叉分叉个VM,然后重用以执行所有测试
默认值为:true
用户属性为:reuseForks
您可以像这样在pom.xml中设置它
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<configuration>
<reuseForks>false</reuseForks> <!-- This will make sure to spawn a fresh jvm for each test -->
</configuration>
</plugin>

请尝试以下配置

总是
我怀疑测试用例必须在单独的类中才能利用这一点。是的,但您可以使用forkMode
的组合(现在已弃用)与parallel
选项一起,在方法级别而不是类级别实现JVM分离。我建议不要使用这种不推荐使用的技术。正如Bob提到的,apache不推荐使用ITA肯定是有原因的,对于这种技术,您必须将您的测试分为不同的类。@SaifAsif但正如我所说的,我不认为ant修改代码。因为我有很多。这只是一个测试用例。没有简单的方法吗?@saifas如果我编辑了这个问题,你能检查编辑的部分吗?
