一：使用的工具 ：

• TestNG 6.9.10
• Maven 3.5
• IDEA

二：建立maven專案，在pom.xml新增依賴

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
 
>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.ng</groupId>
    <artifactId>com.ng</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>

        <!-- https://mvnrepository.com/artifact/org.testng/testng -->
        <dependency
 
>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>6.9.10</version>
            <scope>test</scope>
        </dependency>

    </dependencies>


</project>

三、第一個例項

package com.hornbill;
 
import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.AfterSuite;

/**
 * 執行順序
 * in beforeSuite
 * in beforeTest
 * in beforeClass
 * in beforeMethod
 * in test case 1
 * in afterMethod
 * in beforeMethod
 * in test case 2
 * in afterMethod
 * in afterClass
 * in afterTest
 * in afterSuite
 */
public class TestFuc {

    // test case 1
    @Test
    public void testCase1() {
        System.out.println("in test case 1");
    }

    // test case 2
    @Test
    public void testCase2() {
        System.out.println("in test case 2");
    }

    @BeforeMethod
    public void beforeMethod() {
        System.out.println("in beforeMethod");
    }

    @AfterMethod
    public void afterMethod() {
        System.out.println("in afterMethod");
    }

    @BeforeClass
    public void beforeClass() {
        System.out.println("in beforeClass");
    }

    @AfterClass
    public void afterClass() {
        System.out.println("in afterClass");
    }

    @BeforeTest
    public void beforeTest() {
        System.out.println("in beforeTest");
    }

    @AfterTest
    public void afterTest() {
        System.out.println("in afterTest");
    }

    @BeforeSuite
    public void beforeSuite() {
        System.out.println("in beforeSuite");
    }

    @AfterSuite
    public void afterSuite() {
        System.out.println("in afterSuite");
    }
}

四、點選右鍵執行，執行結果如下：
