java - 是否可以根据标签多次执行 Cucumber 测试？

问题描述

假设我有以下功能文件，其中两个场景具有不同的标签，如下所示：

Feature: Home Feature
  Tests for the Home page

@Desktop @Tablet @Mobile
Scenario: I should see the correct page title
  Given I navigate to the Home page
  Then the page title should read "test"

@Desktop @Tablet
Scenario: I should see the correct body text
  Given I navigate to the Home page
  Then the body text should read "test"

而且我还有以下Hooks, ChromeWebController, HomeSteps&RunCucumberTest类，是否可以在不同的设备上多次运行场景。例如，带有@Desktop, @Tablet&的场景是否@Mobile可以在每个设备上执行 3 次，而带有 & 的场景可以在每个设备@Desktop @Tablet上执行两次，再次执行一次？或者这需要不同的方法吗？

  public Hooks(ChromeWebController chromeWebController) {
    this.chromeWebController = chromeWebController;
  }

  @Before
  public void beforeScenarioSteps(Scenario scenario) {
    this.scenario = scenario;
    chromeWebController.setDeviceType(scenario.getSourceTagNames());
    chromeWebController.setupChromeDriver();
    scenario.log(HomePageFixture.HOME_PAGE_URL);
  }

  @After
  public void afterScenarioSteps() {
    chromeWebController.quitWebDriver();
  }

解决方案

为设备特定的钩子创建两个（基本上等于设备）包。

包装内移动式挂钩mobile

package mobile;

public class MobileHook {

    @Before("@mobile")
    public void before(Scenario scenario) {
        System.out.println("MOBILE");
    }
}

包装中的平板电脑类型挂钩tablet

package tablet;

public class TabletHook {
    
    @Before("@tablet")
    public void before() {
        System.out.println("TABLET");
    }
}

通用胶水代码应该保存在一个单独的包中，比如stepdefs.

相应地修改跑步者。

@CucumberOptions(plugin = { "summary" }, tags = "@mobile", glue = {"mobile", "stepdefs"})
public class RunCukeMobileIT


@CucumberOptions(plugin = { "summary" }, tags = "@tablet", glue = {"tablet", "stepdefs"})
public class RunCukeTabletIT

基本上降低了相关钩子的可见性。猜猜你需要修改初始化驱动程序的代码。
