[英]Error in maven-failsafe-plugin during parallel tests running
我有一个正在运行的应用程序,它运行集成测试没有任何问题。 我想并行运行并添加
<parallel>classes</parallel> <useUnlimitedThreads>true</useUnlimitedThreads>
到pom文件中的maven-failsafe-plugin部分。
结果,本节如下所示
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<executions>
<execution>
<id>default</id>
<goals>
<goal>integration-test</goal>
</goals>
<configuration>
<includes>
<include>**/IntegrationTestSuite.java</include>
</includes>
<excludes>
<exclude>**/*Tests.java</exclude>
<exclude>**/*Test.java</exclude>
</excludes>
<parallel>classes</parallel>
<useUnlimitedThreads>true</useUnlimitedThreads>
</configuration>
</execution>
</executions>
</plugin>
它运行测试,但在运行结束时出现错误

这里可能出什么问题了?
好吧,我不确定这是否行得通。
但是,如果某些测试方案描述中有括号,则JUnit似乎会失败。 看一下这个问题 。
因此,尝试从测试描述中删除每个括号“()”,然后再次运行。 同样,我不确定这是否行得通。 希望对您有帮助。
最终的解决方案是这样的:
