testng教程之testng.xml的配置和使用，以及参数传递

testng.xml

testng.xml是为了更方便的管理和执行测试用例，同时也可以结合其他工具

 

You can invoke TestNG in several different ways: 你可以用以下三种方式执行测试

 

• With a testng.xml file           直接run as test suite
• With ant                            使用ant
• From the command line      从命令行
• eclipse                              直接在eclipse执行

 

textng.xml 基本格式如下：

<test name="Regression1">
  <groups>
    <run>
      <exclude name="brokenTests"  />
      <include name="checkinTests"  />
    </run>
  </groups>
  
  <classes>
    <class name="test.IndividualMethodsTest">
      <methods>
        <include name="testMethod" />
      </methods>
    </class>
  </classes>
</test>

suite：定义一个测试套件，可包含多个测试用例或测试group

suite 里可以设置是否使用多线程：

parallel="methods": TestNG will run all your test methods in separate threads. Dependent methods will also run in separate threads but they will respect the order that you specified.

parallel="tests": TestNG will run all the methods in the same <test> tag in the same thread, but each <test> tag will be in a separate thread. This allows you to group all your classes that are not thread safe in the same <test> and guarantee they will all run in the same thread while taking advantage of TestNG using as many threads as possible to run your tests.

parallel="classes": TestNG will run all the methods in the same class in the same thread, but each class will be run in a separate thread.

parallel="instances": TestNG will run all the methods in the same instance in the same thread, but two methods on two different instances will be running in different threads.

• parallel="classes"  每个测试用例class级别多线程
• thread-count="3" 线程数为3，可同时执行3个case
• preserve-order="true"  根据官方解释（If you want the classes and methods listed in this file to be run in an unpredictible order, set the preserve-order attribute to false）设置为false乱序执行，设置为true会按照你配置执行
• Parameter标签传递参数

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="classes" thread-count="3">
    <test verbose="2" preserve-order="true" name="TestDebug">  
        <parameter name="driverName" value="chrome" />
        <classes>
            <class name="com.dbyl.tests.Case1" />
            <class name="com.dbyl.tests.JDaddress" />
            <class name="com.dbyl.tests.UseCookieLogin" />
            <class name="com.dbyl.tests.MapTest" />
            <class name="com.dbyl.tests.loginTest" />
        </classes>
    </test> <!-- Test -->
</suite> <!-- Suite -->

参数怎么使用？

     这要在case里添加@Parameters 的annotations

     如果有多个parameter，可以一次传入

package com.dbyl.tests;

import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
/**
 * This Test for verify Parameter annotation
 * @author Young
 *
 */
public class passParameter {

    /**
     * 
     * @param parameter1
     * @param parameter2
     */
    @Parameters({"parameter1","parameter2"})
    @Test(groups="parameter")
    public void parameter(String parameter1,int parameter2 )
    {
        System.out.println("parameter1 is "+parameter1 );
        System.out.println("parameter2 is "+parameter2 );
    }
}


其中testng的配置文件为：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="classes" thread-count="5">
    <test verbose="2" preserve-order="true" name="TestDebug">  
        <parameter name="parameter1" value="parameter1" />
        <parameter name="parameter2" value="123" />
        <classes>
            <class name="com.dbyl.tests.passParameter" />
            <class name="com.dbyl.tests.TestngExample" />
        </classes>
    </test> <!-- Test -->
</suite> <!-- Suite -->

这里使用两个parameter标签，传递两个参数

执行结果如下：     

[TestNG] Running:
C:\Users\workspace\Demo\Parametertestng.xml

[TestRunner] Starting executor for test TestDebug with time out:2147483647 milliseconds.
parameter1 is parameter1
parameter2 is 123

接下来尝试从ant命令行执行test suite

首先在 build配置文件加入：

<taskdef resource="testngtasks" classpath="testng.jar"/>

在target执行文件设置testng.xml路径

<xmlfileset dir="${basedir}" includes="Parametertestng.xml"/>

接下在在命令行执行： ant runTestng

运行结果：

C:\Users\workspace\Demo>ant runTestng
