有办法将POM参数/属性传递给TestNG XML文件吗？

Question

我有个maven项目。是否有方法从TestNg Xml文件中读取pom文件的属性?例如，我想从pom文件中读取应用程序的版本，然后使用@ TestNG注释将其传递给我的测试。

到目前为止，我已经尝试将pom属性直接作为TestNG xml文件中的值传递，但是它没有从pom中获取值。相反，它打印pom属性。

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name ="Implementing Parametrization">
<test name ="Testing Functionality">
<parameter name = "browser" value = "${project.version}" />
<parameter name = "username" value = "test@gmail.com" />
<parameter name = "password" value = "abc@xyz123" />
<classes>
    <class 
name="it.org.seleniumtests.Parametrization.GenericHomePage"/>
</classes>
</test>
</suite>

打印测试中的值:预期结果: 1.2.0和实际结果：${project.version}

我知道我可以在JVM参数中这样做，就像我在这里解释的那样：https://rationaleemotions.wordpress.com/2017/09/29/dynamic-parameterization-in-testng/，但这不是我想要实现的。我已经在pom文件中得到了我需要的值。我希望在我的TestNG xml文件中获取它，这样我就可以将它作为参数传递给我的测试。

注意:利用这种方法的将剥夺您直接在IDE中运行testng套件xml文件的能力(而不会从IDE中调用与maven相关的目标)。

是的，您可以这样做，如下所示：

阅读更多的这里和这堆栈溢出答案。

您需要利用maven资源插件并对其启用筛选，以便Maven开始用实际值替换变量。

将以下内容添加到<build>标记中

<testResources>
  <testResource>
    <directory>src/test/resources</directory>
    <filtering>true</filtering>
  </testResource>
</testResources>

如下所示(请注意，我们并不是指来自src/test/resources的testng套件xml文件，因为这将包含带有占位符的套件文件，但我们需要包含由maven替换的实际值的套件文件，该文件在文件夹中可用，以${project.build.testOutputDirectory}值表示)。

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M1</version>
    <executions>
      <execution>
        <phase>test</phase>
      </execution>
    </executions>
    <configuration>
      <suiteXmlFiles>
        <suiteXmlFile>${project.build.testOutputDirectory}/testng.xml</suiteXmlFile>
      </suiteXmlFiles>
    </configuration>
  </plugin>

下面是testng套件xml文件

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Implementing Parametrization">
  <test name="Testing Functionality">
    <parameter name="version" value="${project.version}"/>
    <classes>
      <class
        name="com.rationaleemotions.IgetInputFromMavenResources"/>
    </classes>
  </test>
</suite>

这是考试课

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

public class IgetInputFromMavenResources {

  @Test
  @Parameters("version")
  public void testMethod(String projectVersion) {
    System.err.println("Project version " + projectVersion);
  }

}

这是执行输出
