Problems encountered

1. Using the Firefox browser, the browser does not start after running and does not complain, because the selenium version is incompatible with the Firefox version

2. No Google driver set, webdriver Driver = new Chromedriver (), Error, resolution:

Add System.setproperty ("Webdriver.chrome.driver", "C:\\java\\chromedriver_win3\\chromedriver.exe");

Set Google's drive, which is the chromedriver.exe,c:\\java\\chromedriver_win3\\chromedriver.exe of the previous download changed to its own path

3. Open Google Browser and do not enter the Url,url column display data and prompted "You are using an unsupported command line tag:--ignore-certificate-errors." Stability and security will decrease. ' Workaround:

Add options.addarguments ("--user-data-dir=c:/users/administrator/appdata/local/google/chrome/user Data/Default"); parameter to prohibit data;

Add options.addarguments ("--start-maximized", "Allow-running-insecure-content", "--test-type"); Tips for removing stability

A section of open Baidu Demo:

Package demo;

Import Java.util.concurrent.TimeUnit;

Import Org.openqa.selenium.By;
Import Org.openqa.selenium.WebDriver;
Import Org.openqa.selenium.chrome.ChromeDriver;
Import org.openqa.selenium.chrome.ChromeOptions;


public class Demo5 {public

	static void Main (string[] args) {
		Webdriver driver = null;
		Chromeoptions options = new Chromeoptions ();
		The presence of data is prohibited by configuration parameters
		Options.addarguments ("--user-data-dir=c:/users/administrator/appdata/local/google/ Chrome/user Data/default ");
		Removing stability and security by configuring parameters indicates a decrease in
		options.addarguments ("--start-maximized", "allow-running-insecure-content", "- Test-type ");
		Set up to start Google Drive
		system.setproperty ("Webdriver.chrome.driver", "C:\\java\\chromedriver_win3\\chromedriver.exe");
		Driver=new chromedriver (options);
		Driver.manage (). Timeouts (). implicitlywait (2, timeunit.seconds);
		Driver.navigate (). to ("http://www.baidu.com/");
