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

testng中引用监听的方式有很多种，采用一种即可
