Can a TestNG cross-browser test be executed with Cucumber runner?(可以使用Cucumber Runner执行TestNG跨浏览器测试吗?)
问题描述
我正在与Cucumber一起使用Selenium Webdriver。我的测试就像预期的那样,有了这个组合。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是否工作良好,我只使用TestNG运行它,没有使用Cucumber。它在Chrome和Firefox浏览器上都能完美运行。
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();
}
}
testng.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测试与我的Cucumber设置集成,以便可以使用Cucumber运行整个测试。为此,我向POM添加了cucumber-testng依赖项,并创建了一个扩展AbstractCucumberTestNG类的Cucumber运行器。我指定了特征文件和STEP定义的位置。步骤定义映射到TestNG测试。
黄瓜切割者:
@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,测试仅在一个浏览器(Chrome)中执行。不知何故,火狐在筹备过程中迷失了方向。我怀疑我从另一个类错误地调用了参数化的TestNG方法。如何成功进行呼叫?
推荐答案
若要使用Cucumber运行TestNG测试,您必须在testng.xml中定义测试运行器类。
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我看到以下要求:
运行同一组测试,但参数值不同。
这应该并行工作,所以这应该是线程安全的。
1为Test Runner类引入TestNG参数
@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批注都应从WebTest
类中删除,它们将不起作用且不是必需的。WebTest
由WebAppStepDefinitions
类显式使用,所有方法都显式调用,而不是由TestNG调用。
因此,根据您的初始要求:
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();
}
