用代码触发testng实现并发测试

有时候希望测试用例能用代码触发，发现testng支持这种操作，于是记录一下:

首先添加testng依赖:

    <dependency>       <groupId>org.testng</groupId>       <artifactId>testng</artifactId>       <version>6.9.10</version>     </dependency>

然后实现要被调用的测试用例:

/**  * testng 注解实现并发测试  */ public class ConcurrentTest {      @Test(threadPoolSize = 10, invocationCount = 10, timeOut = 1000)     public static void display() {         System.out.println(UUID.randomUUID().toString());     } }

再用代码触发执行该测试用例:

/**  * 代码触发testng测试  */ public class TestNgDemo {      public static void main(String[] args) {         /**初始化testNG对象*/         TestNG testNG = new TestNG();         TestListenerAdapter listener = new TestListenerAdapter();          testNG.addListener(listener);          /**添加需要执行的测试类数组*/         testNG.setTestClasses(new Class[]{ConcurrentTest.class});          /**执行测试用例*/         testNG.run();          /**汇总分析*/         List<ITestResult> pass = listener.getPassedTests();         List<ITestResult> failed = listener.getFailedTests();          List<Long> interval = pass.stream().map(x -> (x.getEndMillis() - x.getStartMillis())).collect(Collectors.toList());          /**最大耗时*/         long maxtime = interval.stream().max(Comparator.naturalOrder()).get();          /**最小耗时*/         long mintime = interval.stream().min(Comparator.naturalOrder()).get();          /**平均耗时*/         double avgtime = interval.stream().mapToDouble(i -> i).average().getAsDouble();          System.out.println(String.format("test result: [success: %s],[failure: %s]",pass.size(),failed.size()));          System.out.println(String.format("performance analysis: [maxtime: %s(ms)],[mintime: %s(ms),[avgtime: %s(ms)]]",                 maxtime, mintime, avgtime));     } }
