TestNG 101

最近看了点TestNG，做个入门笔记

0.Maven + TestNG

0a. 创建Maven 项目，pom中添加依赖（可能还需要安装TestNG插件

<dependencies>
        <dependency>
            <groupId>org.testng</groupId>
            <artifactId>testng</artifactId>
            <version>6.8.21</version>
        </dependency>
        <!--报告-->
        <dependency>
            <groupId>org.uncommons</groupId>
            <artifactId>reportng</artifactId>
            <version>1.1.4</version>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.testng</groupId>
                    <artifactId>testng</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>com.google.inject</groupId>
            <artifactId>guice</artifactId>
            <version>3.0</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

0b.项目结构

文件路径是在test目录下

1. 一个简单的case

package com.lernenTestNG;

//1. 常用的import的包
import org.testng.annotations.*;
import org.testng.Assert;

//1. 实际的testcase为类中被@Test注释的方法
public class Lecktion1 {

    @BeforeTest
    public void y_beforeTest(){
        System.out.println("**** BeforeTest ****");
    }

    @BeforeMethod
    public void y_beforeMethod(){
        System.out.println("**** BeforeMethod ****");
    }

    @Test
    public void y_Test1() {
        int a = 1;
        int b = 2;
        int res = a + b;
        System.out.println("y_Test1()");
        System.out.println("result=" + res);
        Assert.assertEquals(res,3);

    }

    @Test
    public void y_Test2() {
        int a = 2;
        int b = 3;
        int res = a + b;
        System.out.println("y_Test2()");
        System.out.println("result=" + res);
//       3. Assert.XXX只能在testcase中使用
        Assert.assertEquals(res,5);

    }

    @Test
    public void y_Test3() {
        int a = 2;
        int b = 4;
        int res = a + b;
        System.out.println("y_Test3()");
        System.out.println("result=" + res);
        Assert.assertEquals(res,5);

    }

    @AfterMethod
    public void y_AfterMethod(){
        System.out.println("**** AfterMethod ****");
    }

    @AfterTest
    public void y_AfterTest(){
        System.out.println("**** AfterTest ****");
    }
}

2.常用注解

2a. @Test  ——测试执行主体，作用域为Public

@Test 的可选参数

// 多个参数可以如下使用
// @Test(dataProvider = "",dependsOnGroups = "",groups = {"",""})

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE, ElementType.CONSTRUCTOR})
public @interface Test {
    String[] groups() default {};

    boolean enabled() default true;

    /** @deprecated */
    @Deprecated
    String[] parameters() default {};

    String[] dependsOnGroups() default {};

    String[] dependsOnMethods() default {};

    long timeOut() default 0L;

    long invocationTimeOut() default 0L;

    int invocationCount() default 1;

    int threadPoolSize() default 0;

    int successPercentage() default 100;

    String dataProvider() default "";

    Class<?> dataProviderClass() default Object.class;

    boolean alwaysRun() default false;

    String description() default "";

    Class[] expectedExceptions() default {};

    String expectedExceptionsMessageRegExp() default ".*";

    String suiteName() default "";

    String testName() default "";

    /** @deprecated */
    boolean sequential() default false;

    boolean singleThreaded() default false;

    Class retryAnalyzer() default Class.class;

    boolean skipFailedInvocations() default false;

    boolean ignoreMissingDependencies() default false;

    int priority() default 0;
}

2b. @BeforeTest、@BeforeClass、@BeforeMethod

2c. @AfterTest、@AfterClass、@AfterMethod

——测试前后setup，teardown，具体执行顺序如名称所示

2d. @DetaProvider  ——数据驱动

public class Lecktion2 {
    //注意大小写
    @Test(dataProvider = "dp")
    public void y_test_dp(int a, int b, int res){
        System.out.println("a is "+ a +", b is " + b + ", res is " + res);
        Assert.assertEquals(a+b,res);
    }

    //@DataProvider只支持修饰方法，源码就是这么写的。。。这边可以改成读取文件、或是其他地方得到数据
    @DataProvider
    public Object[][] dp(){
        return new Object[][]{
                {1,2,3},
                {4,5,6}, 
                {1,1,2}};
    }

    //调用三次y_test_dp,所以y_AfterMethod也会执行三次
    @AfterMethod
    public void y_AfterMethod(){
        System.out.println("**** AfterMethod ****");
    }
}

2e. @Pataneters  ——接受配置文件testng.xml中同名参数到测试用例中使用

引用某个触的文档：http://www.cnblogs.com/TankXiao/p/3888070.html

package TankLearn2.Learn;

import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class ParameterizedTest1 {
    
    @Test
    @Parameters("test1")
    public void ParaTest(String test1){
        System.out.println("This is " + test1);
    }
}

testng.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Suite1">
        <parameter name="test1" value="Tank" />
        <parameter name="test1" value="Xiao" />
    <test name="test12">
        <classes>
            <class name="TankLearn2.Learn.ParameterizedTest1" />
        </classes>
    </test>
</suite>
