Surefire 运行某些测试顺序进行，其他测试并行进行

Question

有没有办法按照 JUnit 的 surefire 插件顺序进行某些测试运行？目前它运行并行所有测试，但有些测试很难转换，如果它们不运行并行就足够了。这是我们的一部分 pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.17</version>
    <dependencies>
      <dependency>
        <groupId>org.apache.maven.surefire</groupId>
        <artifactId>surefire-junit47</artifactId>
        <version>2.17</version>
      </dependency>
    </dependencies>
    <configuration>
        <parallel>all</parallel>
        <threadCount>8</threadCount>
      <includes>
        <include>${includeTest}</include>
        <include>${includeAdditionalTest}</include>
      </includes>
    </configuration>
</plugin>

Answer 1

请参阅 surefire plugin documentation。它提供了一种通过使用 @NotThreadSafe 注释来指定某些测试不是线程安全的方法。

另一种解决方案是使用显式 test inclusions and exclusions 指定两个单独的 surefire 执行。一个执行可以运行在并行模式下，包括线程安全套件，另一个是非线程安全套件。

Answer 2

是的，

将每个顺序测试放在自己的套件中，并将所有并行测试放在一个套件中。然后设置并行属性为类.

 <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

我们可以通过定义多个executions

来实现

 <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <executions>
            <execution>
                <id>unit-test</id>
                <phase>unit-test</phase>
                <goals>
                    <goal>test</goal>
                </goals>
                <configuration>
                    <parallel>methods</parallel>
                    <threadCount>4</threadCount>
                    <perCoreThreadCount>true</perCoreThreadCount>
                    <excludes>
                        <!-- run all UTs (non-ITs) parallel -->
                        <exclude>**/*IT.java</exclude>
                    </excludes>
                </configuration>
            </execution>
            <execution>
                <id>integration-test</id>
                <phase>integration-test</phase>
                <goals>
                    <goal>test</goal>
                </goals>
                <configuration>                 
                    <excludes>
                        <exclude>none</exclude>
                    </excludes>
                    <includes>
                        <!-- run integration tests sequentially -->
                        <include>**/*IT.java</include>
                    </includes>
                </configuration>
            </execution>
       </executions>
    </plugin>
