嗨，我正在使用 Windows XP 和最新版本完成本教程

http://binil.wordpress.com/2006/12/08/automated-smoke-tests-with-selenium-cargo-testng-and-maven/

有人可以告诉我标签是什么。

<parallel>true</parallel>
<threadCount>10</threadCount>

当我使用包含这些标签进行构建时，我遇到了失败：

从surefire-plugin文档中：

并行（仅限TestNG）当您使用并行属性时，TestNG 将尝试在单独的线程中运行所有测试方法，但相互依赖的方法除外，它们将在同一线程中运行以尊重它们的执行顺序.

threadCount (TestNG only) The attribute thread-count allows you to specify how many threads should be allocated for this execution. Only makes sense to use in conjunction with parallel.

There is a section on running tests in parallel on the TestNG page of the plugin documentation. To do this your surefire plugin should be configured like this:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.4.2</version>
  <configuration>
    <parallel>methods</parallel>
    <threadCount>10</threadCount>
  </configuration>
</plugin>

true is not a valid value for the option parallel; try methods (as per the docs)

This might also happen if you use an old version of TestNG.

Try upgrading your dependency to TestNG, for example:

<dependency>
  <groupId>org.testng</groupId>
  <artifactId>testng</artifactId>
  <version>5.11</version>
  <classifier>jdk15</classifier>
  <scope>test</scope>
</dependency>

PS: Many people would typically use version 5.1.
