Cucumber钩子并行执行顺序失效问题排查求助

我基于Selenium框架编写了Cucumber测试用例，串行执行时全部通过，但并行执行时测试失败。核心问题是所有测试共用同一用户，测试流程为：登录DARTTS应用→修改语言并验证→登出后重新登录以验证用户语言设置的持久性，且每个测试对应不同语言。

问题具体表现：测试1执行到登出重登步骤时，测试2已在运行并修改了语言，导致测试1的语言验证失败。我尝试通过Hooks控制场景执行顺序，但未生效，不确定是否实现方式有误。

@Profile @VerifyLanguageSetPortugues
Scenario Outline: Profile tests(Verify App Languages selection Espanol)
Given "guest" user login to app "DARTTS" using "AppAuth"
Then I verify previous language setting is active from app title "<Current AppTitle>"
And I click on language "<Language>"
Then I verify selected language for "<Field1>" "<Field2>" "<Field3>"
And I logout and log back in
And I verify previous language setting is active from app title "<Previous AppTitle>"
When I click on user profile button
Then I should log out of Raven app

Examples:
  | Language  | Current AppTitle  | Previous AppTitle       | Field1                                                                              | Field2                                                     | Field3                                      |

Hooks类代码 #

public class Hooks {
    @Before(order = 1, value = "@VerifyLanguageSetPortugues")
public void portuguesLangBeforeScenario() {
    System.out.println("This should run first");
}

@After(order = 4, value = "@VerifyLanguageSetPortugues")
public void portuguesLangAfterScenario() {
    System.out.println("This should end first");
}

@Before(order = 2,  value = "@VerifyLanguageSetEspanol")
public void espanolLangBeforeScenario() {
    UIPgAct.driverWait(55000);
    System.out.println("This should run second");
}

@After(order = 3,  value = "@VerifyLanguageSetEspanol")
public void espanolLangAfterScenario() {
    System.out.println("This should end second");
    System.out.println("Espanol language is set to true");
}

执行输出 #

11:01:59.545 [TestNG-PoolService-1] INFO  gov.dhs.ice.raven.resources.base - Detected Dartts scenario tag.
11:02:05.474 [TestNG-PoolService-0] INFO  gov.dhs.ice.raven.resources.base - WebDriver setup is complete
This should run first
11:02:05.548 [TestNG-PoolService-1] INFO  gov.dhs.ice.raven.resources.base - WebDriver setup is complete
This should run second

问题根源 #

Cucumber的Hooks order 参数仅能控制同一个场景内的Hooks执行顺序，无法跨线程控制不同场景的并行执行顺序。从执行输出的TestNG-PoolService-0/1可以看出，两个场景被分配到了不同线程，Hooks的order参数和等待逻辑完全无法让第二个场景等待第一个场景完成。

解决方案 #

方案1：为每个测试分配独立用户 #

这是最彻底的解决方式，符合并行测试无状态、互相隔离的核心原则。给每个语言测试分配专属测试用户，修改语言的操作只会影响当前用户，不会干扰其他测试的验证步骤。

方案2：强制目标场景串行执行 #

如果暂时无法新增测试用户，可以通过测试框架配置，让@VerifyLanguageSetPortugues和@VerifyLanguageSetEspanol标签的场景强制串行：

• 若使用TestNG，在testng.xml中配置分组，将目标测试分到同一组并设置线程数为1：

<test name="LanguageTests" parallel="none">
  <groups>
    <run>
      <include name="VerifyLanguageSetPortugues"/>
      <include name="VerifyLanguageSetEspanol"/>
    </run>
  </groups>
</test>

• 若使用Cucumber原生并行配置（如cucumber.properties），给目标场景单独设置并行池，线程数设为1：

cucumber.execution.parallel.enabled=true
cucumber.execution.parallel.config.strategy=fixed
cucumber.execution.parallel.config.fixed.parallelism=2
# 为语言测试组单独配置串行
cucumber.execution.groups.group=language-tests
cucumber.execution.groups.group.language-tests.tags="@VerifyLanguageSetPortugues or @VerifyLanguageSetEspanol"
cucumber.execution.groups.group.language-tests.parallel.config.fixed.parallelism=1

方案3：测试前重置用户语言到初始状态 #

在每个场景的@Before Hook中，先登录用户并将语言重置为默认英文（即Current AppTitle对应的Analyze），再执行后续测试步骤，确保每个测试开始时都是初始状态：

@Before(order = 1, value = "@Profile")
public void resetLanguageBeforeScenario() {
    // 执行登录步骤
    loginToDARTTS("guest", "AppAuth");
    // 检查当前语言，非默认则切换回英文
    if (!getCurrentAppTitle().equals("Analyze")) {
        switchToLanguage("English");
    }
    // 登出，让测试用例自行重新登录
    logoutFromDARTTS();
}

当前Hooks的问题说明 #

你给@VerifyLanguageSetEspanol的@Before添加的55秒等待，只是让当前线程暂停，其他线程（如葡萄牙语测试的线程）仍会继续执行，完全起不到顺序控制的作用。且Hooks的order参数仅对同一个场景内的多个Hooks有效，跨场景不生效。
