Selenium和TestNG都在一个浏览器中进行测试

Question

I have abstract class, where initialize webdriver. All classes with the implementation of the tests are inherited from him. I want to reduce the time of test, open a browser for all tests.

class AbstractClassCase {
    public static WebDriver driver;

    @BeforeClass    
    @Parameters({"webDriver", "applicationHost", "applicationPort", "driverHost", "driverPort",  "username", "password"})
    public void setUp(
        String webDriverIdentifier,
        String applicationHost,
        @Optional String applicationPort,
        @Optional String driverHost,
        @Optional String driverPort,
        @Optional String username,
        @Optional String password){      

        driver = new FirefoxDriver();
        driver.get("localhost");
        login(username, password)

    }

    @AfterСlass
    public void tearDown() {   
        driver.quite();
    }     

}

public class TestButton extends AbstractClassCase {
    @Test
    public void testClickButtonNo() {
        WebElement button = driver.findElement(By.id("button-no"));
        button.click();
        WebElement status = driver.findElement(By.id("button-status"));
        Assert.assertEqual("Cancel", status.getText());
   }
}

and other test class in the same spirit.

How can I reconfigure this class, so that the browser opened once?

Answer 1

If you want to Open Browser at the start once and run all the methods and then close it.

There are 2 steps i would recommend to follow.

Step 1 : Include browser invocation code in methods with @BeforeSuite && @AfterSuite for closing the browser/driversession. This makes sure these tests are run once before and after test suite.

protected static WebDriver Browser_Session;

@BeforeSuite
public void beforeSuite() {
    Browser_Session=new FirefoxDriver();
    Browser_Session.manage().timeouts().implicitlyWait(30000, TimeUnit.MILLISECONDS);
}

@AfterSuite
public void afterSuite() {
    Browser_Session.quit();
}

Step2 : Open testng.xml and include all such classes (test methods) under a single Suite, Thus making sure the browser (via Selenium) is invoked first and then rest all methods are run in the same browser.

Here " Class Init " contains Browser Initiating code and ClassA & ClassB are subclassess of Init.

Hope this helps

If you want to run all test in one instance, i wrote my own WebDriverFactory so here is some examples for help:

    public static WebDriver getDriver(){
       if (driver == null) {
            return new FireFoxDriver();
        } else {
          return driver;
        }
   }

Now remove AfterClass and add this to your class it will shutdown your browser in the end

static {
        Runtime.getRuntime().addShutdownHook(new Thread() {
            @Override
            public void run() {
                try {
                    dismissDriver();
                } catch (Exception e) {
                }
            }
        });
}

 public static void dismissDriver() {
        if (driver != null) {
            try {
                driver.quit();
                driver = null;
            } catch (Throwable t) {
            }
        }
    }
