TestNG in Eclipse, Reference to undefined variable env.DOMAIN_PATH
提问by sujoe
I just got a error when I try to run a unit test in Eclipse with TestNG, the error message is: Reference to undefined variable env.DOMAIN_PATH
当我尝试使用 TestNG 在 Eclipse 中运行单元测试时出现错误，错误消息是：Reference to undefined variable env.DOMAIN_PATH
but this problem does not exist when I run it in Intellj or with maven.
但是当我在 Intellj 或 maven 中运行它时，这个问题不存在。
any one experience this problem?
有人遇到过这个问题吗？
I use Eclipse Mars.2 Release (4.5.2), and updated TestNG plugin version 6.9.12.201607091356

When I was trying to run TestNG, I got the same error. I changed the preferences in Eclipse for TestNG -> Maven so that systemPropertyVariables and environmentVariables are unchecked, and I was able to run the test cases successfully.
当我尝试运行 TestNG 时，我遇到了同样的错误。我在 Eclipse 中更改了 TestNG -> Maven 的首选项，以便取消选中 systemPropertyVariables 和 environmentVariables，并且我能够成功运行测试用例。

you need to enable the 'environmentVariables' option at either Eclipse workspace level preferences or project level properties, for example for workspace level: navigate to Eclipse preference -> TestNG -> Maven -> enable option 'environmentVariables'. By default it's disabled. see more details in the official guide
您需要在 Eclipse 工作区级别首选项或项目级别属性中启用“environmentVariables”选项，例如对于工作区级别：导航到 Eclipse 首选项 -> TestNG -> Maven -> 启用选项“environmentVariables”。默认情况下它是禁用的。在官方指南中查看更多详细信息

In case you are working with maven project, setting your custom property to some default value could resolve this issue. below is a sample.
如果您正在使用 Maven 项目，将自定义属性设置为某个默认值可以解决此问题。下面是一个示例。
<properties>
<environment>local</environment>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<systemPropertyVariables>
<environment>${environment}</environment>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
</build>
you can make use of "environment" property in project using below call.
您可以使用以下调用在项目中使用“环境”属性。
System.getProperty("environment");
