与surefire maven插件并行运行junit测试

Question

It is posible to configure surefire plugin to only run some test in parallel and others in sequence?

Also can surefire forkCount be used to run parallel tests declared into a jUnit Suite?

Answer 1

您可以将单独的 Maven 配置文件与两个不同的 surefire 插件配置一起使用。

Answer 2

A very easy way to do this is as follows:

• Move sequential tests each into its own test suite in junit
• Move parallel tests all into the same suite.
• Set Parallel to "classes"

 configuration> <includes> <include>**/A01TestSuite.java</include> <include>**/A02ServiceTestSuite.java</include> <include>**/A03FlowTestSuite.java</include> </includes> <additionalClasspathElements> <additionalClasspathElement>${webinf.dir}</additionalClasspathElement> </additionalClasspathElements> <systemPropertyVariables> <log4j.configuration>file:${l4j.test}/log4j.test.properties</log4j.configuration> </systemPropertyVariables> <forkMode>always</forkMode> <argLine>-Xms512m -Xmx512m</argLine> <parallel>classes</parallel> <threadCount>10</threadCount> </configuration>

Answer 3

You can add this to the configuration of the maven-surefire-plugin in the pom.xml file.

<configuration>
    <parallel>all</parallel>
    <threadCount>10</threadCount>
    <threadCountSuites>2</threadCountSuites>
    <threadCountClasses>2</threadCountClasses>
    <threadCountMethods>6</threadCountMethods>
    <parallelTestTimeoutInSeconds>3.5</parallelTestTimeoutInSeconds>
    <parallelTestTimeoutForcedInSeconds>5</parallelTestTimeoutForcedInSeconds>
    <perCoreThreadCount>true</perCoreThreadCount>
    <includes>
        <include>**/FunctionTestSuite.java</include>
    </includes>
</configuration>
