Maven如何传递系统属性变量到TestNG

 本文介绍如何传递Maven pom.xml里的系统属性参数到TestNG,文章沿用笔者一贯的风格--例子驱动。

 

解决什么问题

1. 用过WebDriver的都知道,当你启动Chrome或IE的时候都需要设置系统属性, 比如

1     System.setProperty("webdriver.ie.driver", "D:/temp/resources/chromedriver.exe");
2        WebDriver driver = new ChromeDriver();
3        driver.get("http://www.cnblogs.com");

经过本文的学习,在pom.xml里通过插件指定system Property Variables, 就不再需要第一步了。

并且这个值可以通过Maven的命令来改写,比如把路径改成 /home/tmp/chromedriver.exe 详细如何使用见下文。

 

2. 就像开发在不同环境构建系统一样,每种环境都有各自的配置参数,每个环境build前手动修改参数,显然不智能。

测试人员在开发自动化测试时也有多个环境,到底是测试Dev环境呢还是测试QA环境呢还是Production呢, 我们可以用maven 的 profile 来解决。

通过Maven命令传递不同的环境变量,代码根据不同的变量值,取不同的数据来进行初始化。

 

例子详解

在pom.xml里定义Maven surefire plugin

 1         <plugin>
 2                 <groupId>org.apache.maven.plugins</groupId>
 3                 <artifactId>maven-surefire-plugin</artifactId>
 4                 <version>2.16</version>
 5                 <configuration>
 6                     <suiteXmlFiles>
 7                         <suiteXmlFile>
 8                             ${basedir}/src/test/resources/testSuite.xml
 9                         </suiteXmlFile>
10                     </suiteXmlFiles>
11                     <systemPropertyVariables>
12                         <webdriver.chrome.driver>D:/temp/resources/chromedriver.exe</webdriver.chrome.driver>
13                         <webdriver.ie.driver>D:/temp/resources/IEDriverServer.exe</webdriver.ie.driver>
14                         <environment>${demo.automation.environment}</environment>
15                     </systemPropertyVariables>
16                     <testFailureIgnore>true</testFailureIgnore>
17                 </configuration>
18             </plugin>

 

定义 profile, 用来给<environment>属性赋值,默认激活的为QA profile

 1 <profiles>
 2         <profile>
 3             <id>QA</id>
 4             <activation>
 5                 <activeByDefault>true</activeByDefault>
 6             </activation>
 7             <properties>
 8                 <demo.automation.environment>QA</demo.automation.environment>
 9             </properties>
10         </profile>
11         <profile>
12             <id>DEV</id>
13             <properties>
14                 <demo.automation.environment>DEV</demo.automation.environment>
15             </properties>
16         </profile>
17     </profiles>

@Test 很简单的测试方法 读取系统属性值

 1 package com.acxiom.insightlab.automation.util;
 2 
 3 import org.testng.annotations.Test;
 4 
 5 /**
 6  * @Description: For demo purpose
 7  * @author wadexu
 8  *
 9  * @updateUser
10  * @updateDate
11  */
12 public class DemoTest {
13 
14     @Test
15     public void simpleTets() {
16         String chromePath = System.getProperty("webdriver.chrome.driver");
17         String iePath = System.getProperty("webdriver.ie.driver");
18         String env = System.getProperty("environment");
19         
20         System.out.println("Chrome Driver Path: "+ chromePath);
21         System.out.println("IE Driver Path: "+ iePath);
22         System.out.println("Test Environment: "+ env);
23     }
24 
25 }

直接针对这个DemoTest类来 Run as TestNG, 取值都是Null, 因为根本没设置这些属性值

Chrome Driver Path: null
IE Driver Path: null
Test Environment: null
PASSED: simpleTets

===============================================
    Default test
    Tests run: 1, Failures: 0, Skips: 0

应该右击pom.xml -> Run as -> Maven test 如果你用的IDE工具, 或者直接工程目录命令行下运行 mvn test

Chrome Driver Path: D:/temp/resources/chromedriver.exe
IE Driver Path: D:/temp/resources/IEDriverServer.exe
Test Environment: QA
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.754 sec - in TestSuite

Results :

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

注意观察结果,默认的profile 里的 <demo.automation.environment> 值QA被用到了。

可以通过命令行运行 mvn test -P DEV   (这个DEV是Profile的id)

注意观察结果,另一个profile 里的 <demo.automation.environment> 值DEV被用到了。

 

通过命令行运行命令加 -D参数 可以覆盖pom里的变量值

比如运行 mvn test -P DEV -Dwebdriver.chrome.driver=C:/temp/chromedriver.exe -Dwebdriver.ie.driver=C:/temp/IEDriverServer.exe

注意观察结果: Chrome 和 IE Driver path 被覆盖了。

另外:

还可以这样写

<webdriver.chrome.driver>${DRIVER_PATH_CHROME}</webdriver.chrome.driver>

Maven会去取环境变量DRIVER_PATH_CHROME的值。

 

比如在Windows下写个bat 文件

先 SET DRIVER_PATH_CHROME=xxx

然后 cd 到 工程目录下

最后 运行 mvn test

其它操作系统同理。
