请参阅surefire plugin documentation。它提供了一种通过使用@NotThreadSafe注解来指定某些测试不是线程安全的方法。
另一种解决方案是用显式的test inclusions and exclusions指定两个独立的万无一失的执行。一个执行可以在包括线程安全套件的并行模式下运行，另一个执行可以在非线程安全的模式下运行。

我们可以通过定义多个executions

<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>

    </executions>

是的，
将每个顺序测试放在它自己的套件中，并将所有并行测试放在一个套件中。然后设置类的平行属性。

<configuration>

			<include>**/A03FlowTestSuite.java</include>
