有没有办法将 POM parameters/attributes 传递给 TestNG XML 文件？

Question

我有一个 Maven 项目。有没有办法从 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，然后将它从 TestNG xml 传递给我的测试使用@Parameter 注释的文件。

到目前为止，我已尝试将 pom 属性作为值直接传递到 TestNG xml 文件中，但它不会从 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>

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

我知道我可以按照我在此处解释的 JVM 参数来做到这一点：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 文件中有了我需要的值。我想在我的 TestNG xml 文件中获取它，以便我可以将它作为参数传递给我的测试。

注意：利用这种方法将剥夺您直接从 IDE（无需从 IDE)

中调用 Maven 相关目标

是的，您可以如下所示执行此操作：

阅读更多here and also this Whosebug 答案。

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

将以下内容添加到您的 <build> 标签

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

这是您的 surefire 插件条目的样子（请注意，我们不是指来自 src/test/resources 的 testng 套件 xml 文件，因为它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，如 ${project.build.testOutputDirectory}

的值所示

  <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>

这是 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>

这是测试class

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

有没有办法将 POM parameters/attributes 传递给 TestNG XML 文件？

Is there a way to pass POM parameters/attributes to TestNG XML file?

maven

testng

pom.xml

testng.xml
