如何让JUnit测试用例并行执行？

Question

可能重复：
Running junit tests in parallel?

我发现里面的JUnit测试案例中，依次执行，如何使他们并行执行？

Answer 1

Junit4提供使用ParallelComputer平行特征：

public class ParallelComputerTest { 

    @Test 
    public void test() {  
     Class[] cls={ParallelTest1.class,ParallelTest2.class }; 

     //Parallel among classes 
     JUnitCore.runClasses(ParallelComputer.classes(), cls); 

     //Parallel among methods in a class 
     JUnitCore.runClasses(ParallelComputer.methods(), cls); 

     //Parallel all methods in all classes 
     JUnitCore.runClasses(new ParallelComputer(true, true), cls);  
    } 

    public static class ParallelTest1 { 
     @Test public void a(){} 
     @Test public void b(){} 
    } 

    public static class ParallelTest2 { 
     @Test public void a(){} 
     @Test public void b(){} 
    } 
} 

Answer 2

下面是一些示例代码。这对我来说真的很好。 ExecutorService的。

public class TestCases { 
    static ExecutorService exe ; 
    public static void main(String[] args) throws Throwable { 
     test1() ; 
     test2() ; 
     test3() ; 
    } 
    public static void test1() { 
     exe = Executors.newCachedThreadPool() ; 
     for (int i = 0 ; i < 10 ; i++) { 
      Test1 test1 = new Test1() ; 
      exe.execute(test1) ; 
     } 
     exe.shutdown() ; 
     while(!exe.isShutDown()) { 
     } 
    } 
    //same for test2 and test3 
} 

public class Test1 implements Runnable { 
    public Test1() { 
    } 
    @Test 
    public myTest throws Throwable { 
    } 
}
