可以TestNG跨浏览器测试执行与cucumber运行？

Question

我正在用cucumber和硒网络司机一起工作。我的测试工作与预期的组合。为了实现跨浏览器测试，我添加了TestNG框架。为了验证我的跨浏览器测试运行良好，我单独使用TestNG运行了它，没有使用cucumber。它在Chrome和火狐浏览器中都运行完美。

public class WebTest {


  WebDriver driver = null;
  BasePageWeb basePage;
  public String browser;


  @Parameters({ "Browser" })
  public WebTest(String browser) {
    this.browser = browser;
  }

  
  @BeforeClass
  public void navigateToUrl() {
    switch (browser) {

      case "CHROME":
        WebDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        break;

      case "FF":
        WebDriverManager.firefoxdriver().setup();
        driver = new FirefoxDriver();
        break;

      default:
        driver = null;
        break;
    }
    driver.get("https://demosite.executeautomation.com/Login.html");

  }

  @Test
  public void loginToWebApp() {

    basePage = new BasePageWeb(driver);
    basePage.enterUsername("admin")
            .enterPassword("admin")
            .clickLoginButton();

    driver.quit();
  }

}

测试开始了。xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Suite" parallel="tests" thread-count="5">

    <test name="Chrome Test">
        <parameter name="Browser" value="CHROME"/>
        <classes>
            <class name="tests.web.WebTest"/>
        </classes>
    </test>
    <test name="Firefox Test">
        <parameter name="Browser" value="FF"/>
        <classes>
            <class name="tests.web.WebTest"/>
        </classes>
    </test>
</suite>

我需要将TestNG测试与Cucumber设置相集成，这样我就可以用Cucumber运行整个测试。为此，我将cucumber testng依赖项添加到POM中，并创建了一个cucumber runner来扩展AbstractCucumberTestNG类。我指定了特征文件和步骤定义的位置。步骤定义映射到TestNG测试。

cucumber跑步者：

@CucumberOptions(
                plugin = {"pretty", "html:target/surefire-reports/cucumber",
                        "json:target/surefire-reports/cucumberOriginal.json"},
                glue = {"stepdefinitions"},
                tags = "@web-1",
                features = {"src/test/resources/features/web.feature"})
          
   

 public class RunCucumberNGTest extends AbstractTestNGCucumberTests {
    }

步骤定义：

public class WebAppStepDefinitions {
      private final WebTest webTest = new WebTest("CHROME"); //create an object of the class holding the testng test. If I change the argument to FF, the test will run only on Firefox
      static boolean prevScenarioFailed = false;
    
    
      @Before
      public void setUp() {
        if (prevScenarioFailed) {
          throw new IllegalStateException("Previous scenario failed!");
        }
    
      }
    
      @After()
      public void stopExecutionAfterFailure(Scenario scenario) throws Exception {
        prevScenarioFailed = scenario.isFailed();
      }
    
      @Given("^I have navigated to the web url \"([^\"]*)\"$")
      public void navigateToUrl(String url) {  test
        webTest.navigateToUrl(url); //calling the first method holding the testng
      }
    
    
      @When("^I log into my web account with valid credentials as specicified in (.*) and (.*)$")
      public void logintoWebApp(String username, String password) {
        webTest.loginToWebApp(username, password); //calling the second method holding the testng
      }
    }

在运行该类时，测试只在一个浏览器（Chrome）中执行。不知怎的，Firefox在构建过程中迷失了方向。我怀疑我从另一个类错误地调用了参数化的TestNG方法。如何成功地拨打电话？

对于使用Cucumber运行TestNG测试，您必须在testng.xml.中定义TestRunner类

您的Test Runner类是RunCucumberNGTest。

因此，xml应该如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Suite" parallel="tests" thread-count="5">

    <test name="Chrome Test">
        <parameter name="Browser" value="CHROME"/>
        <classes>
            <class name="some.package.name.RunCucumberNGTest"/>
        </classes>
    </test>
    <test name="Firefox Test">
        <parameter name="Browser" value="FF"/>
        <classes>
            <class name="some.package.name.RunCucumberNGTest"/>
        </classes>
    </test>
</suite>

从这个xml中，我看到了下一个需求：

运行相同的测试集，但使用不同的参数值。

这应该是并行的，所以这应该是线程安全的。

1.为Test Runner类引入TestNG参数

java prettyprint-override">@CucumberOptions(
                plugin = {"pretty", "html:target/surefire-reports/cucumber",
                        "json:target/surefire-reports/cucumberOriginal.json"},
                glue = {"stepdefinitions"},
                tags = "@web-1",
                features = {"src/test/resources/features/web.feature"})
public class RunCucumberNGTest extends AbstractTestNGCucumberTests {

    // static thread-safe container to keep the browser value
    public final static ThreadLocal<String> BROWSER = new ThreadLocal<>();

    @BeforeTest
    @Parameters({"Browser"})
    public void defineBrowser(String browser) {
        //put browser value to thread-safe container
        RunCucumberNGTest.BROWSER.set(browser);
        System.out.println(browser);
    }

}

2.使用步骤定义类中的值

public class WebAppStepDefinitions {
      private WebTest webTest;
      static boolean prevScenarioFailed = false;
    
      @Before
      public void setUp() {
        if (prevScenarioFailed) {
          throw new IllegalStateException("Previous scenario failed!");
        }
        //get the browser value for current thread
        String browser = RunCucumberNGTest.BROWSER.get();
        System.out.println("WebAppStepDefinitions: " + browser);
        //create an object of the class holding the testng test. If I change the argument to FF, the test will run only on Firefox
        webTest = new WebTest(browser);
      }
    
      @After
      public void stopExecutionAfterFailure(Scenario scenario) throws Exception {
        prevScenarioFailed = scenario.isFailed();
      }
    
      @Given("^I have navigated to the web url \"([^\"]*)\"$")
      public void navigateToUrl(String url) {
        webTest.navigateToUrl(url); //calling the first method holding the testng
      }
    
    
      @When("^I log into my web account with valid credentials as specicified in (.*) and (.*)$")
      public void logintoWebApp(String username, String password) {
        webTest.loginToWebApp(username, password); //calling the second method holding the testng
      }

}

注意：所有TestNG注释都应该从WebTest类中删除，它们不起作用，也不是必需的WebTest由WebAppStepDefinitions类显式使用，所有方法均显式调用，而不是由TestNG调用。

因此，根据您最初的要求：

public class WebTest {

  WebDriver driver = null;
  BasePageWeb basePage;
  public String browser;

  public WebTest(String browser) {
    this.browser = browser;
  }

  public void navigateToUrl(String url) {
    switch (browser) {

      case "CHROME":
        WebDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        break;

      case "FF":
        WebDriverManager.firefoxdriver().setup();
        driver = new FirefoxDriver();
        break;

      default:
        driver = null;
        break;
    }
    driver.get(url);

  }

  public void loginToWebApp(String username, String password) {

    basePage = new BasePageWeb(driver);
    basePage.enterUsername(username)
            .enterPassword(password)
            .clickLoginButton();

    driver.quit();
  }
