testng自定义注解

在testng中大部分的注解已经可以满足我们测试的需求，但是在测试的时候想要通过注解的方式加入自己测试一些内容，比如测试项目测试描述验证点等信息，可通过自定义注解的方式实现。

具体操作步骤如下：

1.创建maven工程

自行查询创建maven工程的方法

2.pom文件中引入testng依赖

    <!-- 配置testng依赖 -->

     <dependency>

       <groupId>org.testng</groupId>

       <artifactId>testng</artifactId>

       <version>6.9.8</version>

     </dependency>

3.创建自定义注解类

package com.test.annotation;

import java.lang.annotation.ElementType;

import java.lang.annotation.Retention;

import java.lang.annotation.RetentionPolicy;

import java.lang.annotation.Target;  

@Retention(RetentionPolicy.RUNTIME)

@Target(ElementType.METHOD)

public @interface TestDescription {

	//测试项

    public String item() default "";

    //测试描述

    public String description() default "";

    //验证点

    public String verification() default "";

}

4.创建监听

package com.test.annotation;

import org.testng.IInvokedMethod;

import org.testng.IInvokedMethodListener;

import org.testng.ITestContext;

import org.testng.ITestListener;

import org.testng.ITestNGMethod;

import org.testng.ITestResult;  

public class MyAnnotationListener implements IInvokedMethodListener, ITestListener {  

	public String item;

    public String description;

    public String verification;  

    public void onTestStart(ITestResult result) {

        System.out.println("onTestStart");

        item = result.getMethod().getConstructorOrMethod().getMethod().getAnnotation(TestDescription.class).item();

        description = result.getMethod().getConstructorOrMethod().getMethod().getAnnotation(TestDescription.class).description();

        verification = result.getMethod().getConstructorOrMethod().getMethod().getAnnotation(TestDescription.class).verification();

        System.out.println("item: " + item + " description: " + description);

        System.out.println("verification: " + verification);

    }  

    public void onTestSuccess(ITestResult result) {

        System.out.println("onTestSuccess");  

    }  

    public void onTestFailure(ITestResult result) {

        System.out.println("onTestFailure");  

    }  

    public void onTestSkipped(ITestResult result) {

        System.out.println("onTestSkipped");  

    }  

    public void onStart(ITestContext context) {

        System.out.println("onStart");

        for(ITestNGMethod m1 : context.getAllTestMethods()) {

            if(m1.getConstructorOrMethod().getMethod().isAnnotationPresent(TestDescription.class)) {

            	item = m1.getConstructorOrMethod().getMethod().getAnnotation(TestDescription.class).item();

                description = m1.getConstructorOrMethod().getMethod().getAnnotation(TestDescription.class).description();

                verification = m1.getConstructorOrMethod().getMethod().getAnnotation(TestDescription.class).verification();

                System.out.println("onStart_item:"+item);

                System.out.println("onStart_description:"+description);

                System.out.println("onStart_verification:"+verification);

            }

        }  

    }  

    public void onFinish(ITestContext context) {

        System.out.println("onFinish");  

    }

	@Override

	public void beforeInvocation(IInvokedMethod method, ITestResult testResult) {

		// TODO Auto-generated method stub

	}

	@Override

	public void afterInvocation(IInvokedMethod method, ITestResult testResult) {

		// TODO Auto-generated method stub

	}

	@Override

	public void onTestFailedButWithinSuccessPercentage(ITestResult result) {

		// TODO Auto-generated method stub

	}  

}

5.创建测试类，并引用Listener

package com.test.annotation;

import org.testng.annotations.Listeners;

import org.testng.annotations.Test;

@Listeners(com.test.annotation.MyAnnotationListener.class)

public class TestMyAnnotationListener {  

    @TestDescription(item = "测试项1", description="描述1;",verification="验证1")

    @Test

    public void test001(){

        System.out.println("运行test001");

    }

    @TestDescription(item = "测试项2", description="描述2;",verification="验证2")

    @Test

    public void test002(){

    	System.out.println("运行test002");

    }

}

@Listeners(com.test.annotation.MyAnnotationListener.class)  此行代码为引用监听

6.运行测试类结果如下：

onStart

onStart_item:测试项1

onStart_description:描述1;

onStart_verification:验证1

onStart_item:测试项2

onStart_description:描述2;

onStart_verification:验证2

onTestStart

item: 测试项1 description: 描述1;

verification: 验证1

运行test001

onTestSuccess

onTestStart

item: 测试项2 description: 描述2;

verification: 验证2

运行test002

onTestSuccess

onFinish

PASSED: test001

PASSED: test002

===============================================

    Default test

    Tests run: 2, Failures: 0, Skips: 0

Default suite

Total tests run: 2, Failures: 0, Skips: 0

testng中引用监听的方式有很多种，采用一种即可
