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5，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:UsersworkspaceDemoParametertestng.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="${basedir}" includes="Parametertestng.xml"/>
详细：
1 <?xml version="1.0"?>
2 <project name="Demo" default="run" basedir=".">
3 <echo message="Start selenium Grid" />
4 <echo message="import libs" />
5 <path id="run.classpath">
6 <fileset dir="${basedir}">
7 <include name="lib/poi/*.jar" />
8 <include name="lib/poi/lib/*.jar" />
9 <include name="lib/testng.jar" />
10 <include name="lib/sikuli-script.jar" />
11 <include name="lib/*.jar" />
12 </fileset>
13 <fileset dir="${basedir}/lib/selenium">
14 <include name="selenium-java-2.45.0.jar" />
15 <include name="libs/*.jar" />
16 </fileset>
17 </path>
18 <taskdef name="testng" classname="org.testng.TestNGAntTask" classpathref="run.classpath" />
19 <target name="clean">
