How to set chrome browser window resolution in jenkins - maven

Question

Am running the Selenium webdriver(Maven Project) Scripts through Jenkins by calling pom.xml file. I have set below mentioned browser resolution
driver.manage().window().maximize();
Dimension defaultSize = new Dimension(2560,1440);
driver.manage().window().setSize(defaultSize);
However, while running the scripts through Jenkins, Chrome browser window is not set to the new dimension.
Note : In Local machine it's working fine..

Copied from my question - GOCD pipeline, Selenium ChromeDriver window size is not set
his issue looks to have been caused by two issues,
1- When mvn clean test is run from the IDE this process runs under your current user. However, when run by the Continuous Integration environment, the process is owned by the System process. so does not have the same access to resources.
2 When run from the IDE, chrome will pop up. When run from the CI environment I assumed that it defaulted chrome to run in headless mode. It does not, you have to set the --headless argument so my configuration that now works is as follows
public class GoogleChrome extends Base {
private static final Logger logger = LogManager.getLogger(GoogleChrome.class);
private String rootPath = System.getProperty("user.dir").replace("\\","/");
#Autowired
protected WebDriver driver;
public WebDriver startChromeDriver() {
logger.info("Chrome driver path : " + rootPath + "/../Tools/Drivers/chromedriver.exe");
System.setProperty("webdriver.chrome.driver", rootPath + "/../Tools/Drivers/chromedriver.exe");
Map<String, Object> prefs = new HashMap<String, Object>();
logger.info("Disabling Chrome's credentials service");
prefs.put("credentials_enable_service", false);
logger.info("Disabling Chrome's password manager");
prefs.put("password_manager_enabled", false);
final String regex = "^\\D*$";
final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
final Matcher matcher = pattern.matcher(System.getProperty("user.name"));
boolean isHuman = matcher.matches();
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", prefs);
logger.info("Disabling Chrome's info bars");
options.addArguments("disable-infobars");
options.addArguments("--incognito");
options.addArguments("--disable-gpu");
options.addArguments("--no-sandbox");
options.addArguments("--allow-insecure-localhost");
if (isHuman){
logger.info("Chrome starting maximized - isHuman: " +isHuman + " process run by " +System.getProperty("user.name"));
options.addArguments("--start-maximized");
} else {
logger.info("Chrome starting headless - isHuman: " +isHuman + " process run by " +System.getProperty("user.name")) ;
options.addArguments("--headless");
options.addArguments("--window-size=1980,1080");
}
options.setAcceptInsecureCerts(true);
try {
logger.info("Killing Chrome browser");
Runtime.getRuntime().exec("taskkill /F /IM chrome.exe");
} catch (IOException e) {
logger.error("Task Kill IOException : " + e.getMessage());
}
logger.info("Starting Chrome browser...");
sleep(2);
driver = new ChromeDriver(options);
logger.info("Window size: "+ driver.manage().window().getSize());
driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
return driver;
}
}

Chrome disallows setting the size larger than the system's screen resolution width, the problem may be this in your case. Some workaround could be to maximize the window to at least have the largest window available on that system.
While sometimes old chromedriver also cause the issue
If still problem exist then you can change the resolution by chrome option as :
chromeOptions.addArguments("window-size=1936,1056");
Full code will be like :-
System.setProperty("webdriver.chrome.driver","D:\\Workspace\\JmeterWebdriverProject\\src\\lib\\chromedriver.exe");
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("window-size=1936,1056");
WebDriver driver = new ChromeDriver(chromeOptions);
driver.get("https://www.google.co.in/");
Hope it will help you :)
