Answer 1

Check your chromeDriver Version and confirm weather it is compatible with your chorme version.

And check this : https://sites.google.com/a/chromium.org/chromedriver/downloads

Answer 2

worked for me like a charm:

• npm update protractor -g (globally update protractor)
• webdriver-manager update

Answer 3

ChromeOptions options = new ChromeOptions();

options.addArguments("start-maximized"); System.setProperty("webdriver.chrome.driver","/Users/vedavyasa/bank_emulation/test/lib/chromedriver"); webDriver = new ChromeDriver(options);
