Selenium/TestNG: Failed Configuration afterClass

Question

I searched around here on stackoverflow, and it seems that many people have similar issues. However, all the fixes in those thread didn't apply to my case, so I am stuck and decided to create another question regarding this problem.

I feel like I am missing some small thing. It has worked in the beginning and now I always get these errors.

Code:

The before class, note, I use parameters in my XML to finetune behaviour:

@Parameters({"env","cleanup"})
@BeforeClass(alwaysRun=true)
public void beforeClass(String env, String cleanup) {
    System.setProperty(ESCAPE_PROPERTY, "false");
    Reporter.setEscapeHtml(false);
    ChromeOptions chromeOptions = new ChromeOptions();
    Map<String, Object> preferences = new Hashtable<String, Object>();
    chromeOptions.setExperimentalOption("prefs", preferences);
 // disable flash and the PDF viewer
    preferences.put("plugins.plugins_disabled", new String[]{
        "Adobe Flash Player", "Chrome PDF Viewer"});
    preferences.put("download.default_directory",downloadFolder+"\\"+getTestName()+" ("+env+")");

    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    chromeOptions.setBinary("folder\\chrome.exe");
    capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);


    System.setProperty("webdriver.chrome.driver", "C:\\Users\\myname\\ChromeDriver.exe");
    driver = new AGDriver(capabilities);  
    driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
    driver.cleanup_required = cleanup.equals("yes");
    driver.saveVariable("env", env);
}

I have created a slight variation on the webdriver to give it global state (dont judge ;) ), however I can't imagine this breaking things:

public class AGDriver extends ChromeDriver {
Map<String, String> map = new HashMap<String, String>();


public AGDriver(DesiredCapabilities capabilities) {
    super(capabilities);
}

public void saveVariable(String name, String value) {
    map.put(name, value);
}

public String getVariable(String name) {
    return map.get(name);
}

public boolean hasVariable(String name) {
    return map.containsKey(name);
}

At the end of my test case base file, I have this:

@AfterClass(alwaysRun=true)
public void afterClass() {
    try {
        if(driver.cleanup_required) {
            driver.quit();
        }
    } catch(Exception e) {
        System.out.println("Driver teardown failed");
        e.printStackTrace();
    }
}

Problem:

This results in the next errors:

If some code is missing that you need, don't hesitate to ask and I will add it to the question.

Thanks in advance

instead of `driver.quit` try `driver.close()` method in `AfterClass` method — Naveen Kumar R B, Feb 13 '17 at 09:54
@Naveen That seems to work. Any idea why quit wouldn't work? As far as I understand, quit is used to clean up the driver and browser when you're done, close just closes a window. Am I wrong to expect quit to work in this case? — TimoV, Feb 13 '17 at 10:01
what you assumed is correct. close is for current window. quit is for complete cleanup (kill driver processes). what I suggested is workaround. I am not sure why `quit` is NOT working. Might be a bug in `3.0` version. — Naveen Kumar R B, Feb 13 '17 at 10:05
Just tried. In my case restarting `Eclipse` with `Admin Privileges` solve similar issue in `Windows 10`. my answer here http://stackoverflow.com/a/42202681/2575259 — Naveen Kumar R B, Feb 13 '17 at 11:15
what selenium jars are you using? client or server? In my case, `selenium-standalone-server-3.0.1` ran without any issues for `driver.quit` after restarting the eclipse with admin privileges. — Naveen Kumar R B, Feb 13 '17 at 11:18
I am not supposed to run these tests with admin privilege. These are to run unattended on a server. I am using Selenium-java-2.53 (client I guess), jna 4.1 and testng 6.9.9, on windows 7 — TimoV, Feb 13 '17 at 15:07
