TestNG的使用技巧

标签：java 技巧 testng 使用 Test org TestNG public out

TestNG简介

Testng是一套开源测试框架，是从Junit继承而来，testng意为test next generation

创建maven项目，添加依赖

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.14.3</version>
    <scope>test</scope>
</dependency>

常用注解

@BeforeSuite / @AfterSuite @BeforeTest / @AfterTest @BeforeClass / @AfterClass，在类运行之前/后运行 @BeforeMethod / @AfterMethod，在测试方法之前/后运行

分组测试

场景︰只想执行个别或者某一部分的测试用例

package com.qzcsbj;
 
import org.testng.annotations.AfterGroups;
import org.testng.annotations.BeforeGroups;
import org.testng.annotations.Test;
 

public class TestGroups {
    @Test(groups = "login")
    public void testa(){
        System.out.println("TestIgnore.testa");
    }
 
    @Test(groups = "submitOrder")
    public void testb(){
        System.out.println("TestIgnore.testb");
    }
 
    @Test(groups = "submitOrder")
    public void testc(){
        System.out.println("TestIgnore.testc");
    }
 
    @BeforeGroups("submitOrder")
    public void testBeforeGroups(){
        System.out.println("TestGroups.testBeforeGroups");
    }
 
    @AfterGroups("submitOrder")
    public void testAfterGroup(){
        System.out.println("TestGroups.testAfterGroup");
    }
}
结果
TestIgnore.testa
TestGroups.testBeforeGroups
TestIgnore.testb
TestIgnore.testc
TestGroups.testAfterGroup   

xml方式
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="All Test Suite">
    <!--<test verbose="2" preserve-order="true" name="test">-->
    <test name="test">  <!--test必须有name属性-->
        <groups>
            <run>
                <include name="submitOrder"/>
            </run>
        </groups>
        <classes>
            <class name="com.qzcsbj.TestGroups"/>
        </classes>
    </test>
</suite>

输出结果：

TestGroups.testBeforeGroups
TestIgnore.testb
TestIgnore.testc
TestGroups.testAfterGroup

依赖测试

字符串数组，默认是空 dependsOnMethods和BeforeMethod的区别是： BeforeMethod是每个方法前都要执行，而dependsOnMethods只是依赖的方法前执行

package com.qzcsbj;
 
import org.testng.annotations.Test;
 

public class TestDepend {
    @Test(dependsOnMethods = {"test2"})
    public  void test(){
        System.out.println("TestAnnotation.test");
    }
 
    @Test
    public  void test2(){
        System.out.println("TestAnnotation.test2");
    }
}


运行结果：
TestAnnotation.test2
TestAnnotation.test

如果被依赖方法执行失败，有依赖关系的方法不会被执行；应用场景，登录失败，就不能进行下单等操作

package com.qzcsbj;
 
import org.testng.annotations.Test;
 

public class TestDepend {
    @Test(dependsOnMethods = {"test2"})
    public  void test(){
        System.out.println("TestAnnotation.test");
    }
 
    @Test
    public  void test2(){
        System.out.println("TestAnnotation.test2");
        throw new RuntimeException();  // 抛出一个异常
    }
    }
运行结果：

TestAnnotation.test2
 
java.lang.RuntimeException
    at com.qzcsbj.TestDepend.test2(TestDepend.java:19)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

    at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:719)
    at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:989)

超时

timeout属性的单位为毫秒。

package com.qzcsbj;
 
import org.testng.annotations.Test;

public class TestTimeOut {
    @Test(timeOut = 1000)  // 单位为毫秒值，期望在1秒内得到结果
    public void test() throws InterruptedException {
        System.out.println("TestTimeOut.test");
        Thread.sleep(500);
    }
 
    @Test(timeOut = 1000)
    public void test2() throws InterruptedException {
        System.out.println("TestTimeOut.test2");
        for (int i = 10; i > 0; i--) {
            Thread.sleep(101);
            System.out.println(i);
        }
        System.out.println("执行结束。");
    }
    }
    
    
    结果：
    TestTimeOut.test2

 
org.testng.internal.thread.ThreadTimeoutException: Method com.qzcsbj.TestTimeOut.test2() didn't finish within the time-out 1000

断言

package com.qzcsbj;

public class Add {
    public int sum(int a, int b){
        return a+b;
    }
}




package com.qzcsbj;
 
import org.testng.Assert;
import org.testng.annotations.Test;
 
public class MyTest {
    @Test
    public void test(){
        Add add = new Add();
        int actual = add.sum(1, 2);
        int expect = 2;
        Assert.assertEquals(actual,expect);
    }
}

参数化（数据驱动测试）

两种方式向测试方法传递参数：　　利用testng.xml定义parameter 　　利用DataProviders

xml文件参数化

package com.qzcsbj;
 
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
 

public class TestParameter {
    @Test
    @Parameters({"name","id"})
    public void test(String name, int id){
        System.out.println("name=" + name + ", id=" + id);
    }
}

xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="All Test Suite">
    <!--<test verbose="2" preserve-order="true" name="test">-->
    <test name="test">  <!--test必须有name属性-->
        <classes>
            <class name="com.qzcsbj.TestParameter">
                <parameter name="name" value="hyqtest"/>
                <parameter name="id" value="1"/>
            </class>
        </classes>
    </test>
</suite>

结果：
name=hyqtest, id=12

DataProvider参数化

代码和数据未分离

package com.qzcsbj;
 
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
 

public class TestDataProvider {
    @Test(dataProvider="data")  // 和下面的name对应起来
    public void testDataProvider(String name, int id){
        System.out.println("name=" + name + ", id=" + id);
    }
    @DataProvider(name = "data")  // 如果没有指定name，上面就写下面的方法名：providerData
    public Object[][] providerData(){
        Object[][] datas = new Object[][]{
                {"zhangsan",1001},
                {"lisi",1002},
                {"wangwu",1003}
        };
        return datas;
    }
}

name=zhangsan, id=1001
name=lisi, id=1002
name=wangwu, id=1003

代码和数据分离，数据存放在excel中

LoginCase.java 用课程中的数据类型封装

package com.qzcsbj;
 
import com.qzcsbj.HttpPostRequest;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import java.util.HashMap;
 
 

public class LoginCase {
    @Test(dataProvider = "datasFromExcel")  // 多条数据，且数据和代码分离
    public void test(String username, String password){
        String url = "http://127.0.0.1:9999/login";
        HashMap<String, String> params = new HashMap<String, String>();
        params.put("username", username);
        params.put("password", password);
        String res = HttpPostRequest.postRequest(url, params);
        System.out.println("入参：username=" + username + ", password=" + password);
        System.out.println("响应：" + res);
        System.out.println("============================\n");
    }
 
    @DataProvider(name = "datasFromExcel")
    public Object[][] datasFromExcel(){
        Object[][] datas = ExcelUtil.getdataFromExcel("E:\\case.xlsx");
        return datas;
    }
}

进一步优化

每行数据封装到对象或者map，返回：Iterator<Object[]> 每个一维里面是一个对象或者map
