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));
    }
}

最后执行结果如下:
