如果 @AfterMethod 失败，TestNG 会跳过后续的 @Test(invocationCount = 3) 运行

Question

使用 testNG 运行此代码：

package org.example;

import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class Test1 {

    @BeforeMethod(alwaysRun = true)
    public void before() throws Exception {
        System.out.println("BEFORE, thread ID=" + Thread.currentThread().getId());
    }

    @AfterMethod(alwaysRun = true)
    public void after() throws Exception {
        System.out.println("AFTER, thread ID=" + Thread.currentThread().getId());
        throw new Exception("Error!");
    }

    @Test(alwaysRun = true, invocationCount = 3, threadPoolSize = 1)
    public void test() throws Exception {
        System.out.println("TEST, thread ID=" + Thread.currentThread().getId());
    }

}

返回

BEFORE, thread ID=1
TEST, thread ID=1
AFTER, thread ID=1
BEFORE, thread ID=1
AFTER, thread ID=1
BEFORE, thread ID=1
AFTER, thread ID=1

@Test 方法仅第一次运行，之后被跳过。如何实现这一点，即避免跳过 @Test 方法：

BEFORE, thread ID=1
TEST, thread ID=1
AFTER, thread ID=1
BEFORE, thread ID=1
TEST, thread ID=1
AFTER, thread ID=1
BEFORE, thread ID=1
TEST, thread ID=1
AFTER, thread ID=1

结果显示测试是按顺序运行的，而不是并行运行的。 因此，单个线程被用于运行测试用例的所有 3 次调用。

如果调用需要并行运行，则必须在 testng.xml 文件中设置以下参数：

1. parallel="methods"
2. thread-count="3"

并行运行的工作示例 testng.xml 文件：

<suite name="Run tests in parallel" parallel="methods" thread-count="3">
    <test name="3-threads-in-parallel">
        <classes>
            <class name="com.company.tests.TestClass"/>
        </classes>
    </test>
</suite>
