Selenium + TestNG + Java -> org.openqa.selenium.NoSuchSessionException: invalid session id

Question

I'm trying to run all my tests together instead one by one but I'm getting this error msg.

I'm using TestNG, Selenium 4.1.2, Java, chromedriver manage by import io.github.bonigarcia.wdm.WebDriverManager; This is my BaseClass code, (where I create my setup() method):

    @BeforeMethod(alwaysRun = true)
    public void before(@Optional("chrome") String browser) {

        try {

            WebDriverManager.chromedriver().setup();
            WebDriverManager.firefoxdriver().setup();
    
            if(browser.equals("chrome")){
                driver = new ChromeDriver();
            }else{
                driver = new FirefoxDriver();
            }
    
            driver.get(URL);
            driver.manage().window().maximize();
            
        } catch (Exception e) {
            e.printStackTrace();
        }


    }

    @AfterMethod(alwaysRun = true)
    public void after() {
        try {
            driver.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

I have 2 classes and If I run all my tests, they just run and pass the first test of every class and for the other ones just send me the same error org.openqa.selenium.NoSuchSessionException: invalid session id.

NOTE: If I run one by one manually it works..!! But if I run e.g "maven clean test" which will run a xml within POM, or right click on xml the same error msg appears, I've searched but all mention something about driver.close() or driver.quit() and anything works. Any help could be great :D

@GauravLad inside @beforeMethod, there is... driver = new ChromeDriver(); — bdgv11

Be sure to use driver.quit(). driver.close() won't necessarily quit the driver. (some drivers will quit if there are no longer any browser windows open...) It should also help to include a sleep after quitting the driver. This gives the browser/driver time to cleanup things... especially the file that drops the sessionID. — browsermator

probably the driver.close() in After suite will resolve the issue as there is no session when the other test being started.

Can you try by changing below,

@AfterSuite  
public void after_suite()  
{  
     try {
            driver.close();
        } catch (Exception e) {
            e.printStackTrace();
        } 
      
}

I tried and get a different error msg (I've tried that before), now I'm getting that the mouse hover action doesn't work but is weird because if I run just that test, it works..

dheeraj Over a year ago

That's a different error though, not sure and may be that particular function/step would give details

Element is not able to click now (WaitForElementToBeClickeable Method) [[ChromeDriver: chrome on MAC (74b549057fe70f0d04d7c576e5a89df1)] -> xpath: //*[@id='top-links']/ul/li[2]/a/span[1]]org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document   (Session info: chrome=99.0.4844.83)

This is the error I got. Page tested is http://opencart.abstracta.us and if you look that xpath, there is @dheeraj

You are trying to click the element which is no more available on the page, use proper waits or expected conditions to do the click action

bdgv11 Over a year ago

I have tried with the new waits for selenium 4 using thisnew WebDriverWait(driver, Duration.ofSeconds(5)).until(ExpectedConditions.visibilityOf(element)); or this one driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10)); and the element is just present in the first test case, for the next ones it doesn't
