在Maven构建中并行运行junit测试？

从junit 4.7开始,现在可以在不使用TestNG的情况下并行运行测试.实际上从4.6开始就有可能,但是4.7中有一些修正,这将使它成为一个可行的选择.您也可以使用spring运行并行测试,您可以在这里阅读

受JUnit实验性ParallelComputer跑步者的启发,我已经建立了自己的ParallelSuite和ParallelParameterized跑步者.使用这些运行程序,可以轻松地并行化测试套件和参数化测试.

ParallelSuite.java

public class ParallelSuite extends Suite {

    public ParallelSuite(Class klass, RunnerBuilder builder) throws InitializationError {

        super(klass, builder);

        setScheduler(new RunnerScheduler() {

            private final ExecutorService service = Executors.newFixedThreadPool(4);

            public void schedule(Runnable childStatement) {
                service.submit(childStatement);
            }

            public void finished() {
                try {
                    service.shutdown();
                    service.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
                } catch (InterruptedException e) {
                    e.printStackTrace(System.err);
                }
            }
        });
    }
}

ParallelParameterized.java

public class ParallelParameterized extends Parameterized {

    public ParallelParameterized(Class arg0) throws Throwable {

        super(arg0);

        setScheduler(new RunnerScheduler() {

            private final ExecutorService service = Executors.newFixedThreadPool(8);

            public void schedule(Runnable childStatement) {
                service.submit(childStatement);
            }

            public void finished() {
                try {
                    service.shutdown();
                    service.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
                } catch (InterruptedException e) {
                    e.printStackTrace(System.err);
                }
            }
        });
    }
}

用法很简单.只需将@RunWith注释值更改为其中一个Parallel*类.

@RunWith(ParallelSuite.class)
@SuiteClasses({ATest.class, BTest.class, CTest.class})
public class ABCSuite {}

tempus-fugit提供类似的东西,查看文档了解详情.它依赖于JUnit 4.7,你只需将测试标记为@RunWith(ConcurrentTestRunner).
