Selenium Webdriver fails to load browser through WebDriverManager

Question

We can run our tests in different browsers in selenium Webdriver, previously we need to executable files to run our test in any browser. But now we can achieve without using exe files & with the help of WebDriverManager following below syntax to open chrome browser.

 WebDriverManager.iedriver().setup();
 driver = new ChromeDriver();

Driver class I have defined below code:

public static WebDriver getDriver(){
 try{
 if(driver == null) {
 /* PropertiesFileReader obj=new PropertiesFileReader(); 
 Properties properties=obj.getproperty();
 openBrowser(properties.getProperty("browserName"), properties.getProperty("URL")); */
 WebDriverManager.iedriver().setup();
 driver = new ChromeDriver();
 }
 }catch(Exception e) {
 e.printStackTrace();
 }
 return driver;
 }

I have login page and logintestcase, I am calling getDriver() method from logintest class using below code:

public LoginPage loginpage=PageFactory.initElements(Driver.getDriver(), LoginPage.class);

But I am getting exception :

 SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
 SLF4J: Defaulting to no-operation (NOP) logger implementation
 SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
 java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://chromedriver.storage.googleapis.com/index.html

 at org.openqa.selenium.remote.service.DriverService.findExecutable(DriverService.java:135)
 at org.openqa.selenium.chrome.ChromeDriverService.access000ドル(ChromeDriverService.java:35)

and same code is working with .exe files but not when we are loading through WebDriverManager.

• Upkar Singh: your test failed just because you are using iedriver().setup(); which is used for IE Browser but below you declare the instance of ChromeDriver.
• sarat: The thing I am observed is chrome is updating quietly from behind most of the times if I change the chrome driver to updated version my program start working normally.

Try this may this code help you-

 WebDriver driver;
public static WebDriver getDriver(){
 try{
 if(driver == null) { 
 WebDriverManager.chromedriver().setup();
 driver = new ChromeDriver();
 }
 }catch(Exception e) {
 e.printStackTrace();
 }
 return driver;
 } 

If you want to add more capabilities in webdrivermanager try this too-

WebDriverManager.chromedriver()
 .version("2.40")
 .arch32()
 .proxy("myproxyhostname:80")
 .proxyUser("myusername")
 .proxyPass("myawesomePassword")
.setup();

• Upkar Singh: You need to add following jar file in your classpath: slf4j-simple-1.6.2.jar and for chromedriver exception try to download the correct version by using .Version() capabilitiy of WebDriverManager.
• jay: nable to read VR Path Registry getting for firefoxdriver, refer ccode-- WebDriverManager.firefoxdriver().version("0.21.0").setup(); driver=new FirefoxDriver()
• Upkar Singh: Is your chromeDriver working?
• jay: chrome is working perfectly
