you're in luck.. recently, had helped individual logging in , out of flipkart. here script:

@config(url="http://flipkart.com", browser=browser.firefox) public class testflipkart extends conductor {     @test     public void testloginlogout() {         string username = "<username>";         string password = "<password>";          click(by.cssselector("a[href*='/login']"))         .settext(by.cssselector("input[name='email']"), username)         .settext(by.cssselector("input[name='password']"), password)         .click(by.cssselector("input[type='submit'][value='login']"))          .validatepresent(by.cssselector("li.greeting-link > a"))          .hoverover(by.cssselector("li.greeting-link > a"))          .click(by.cssselector("ul.account-dropdown a[href*='/logout']"))          // should logged out now.         .validatepresent(by.cssselector("a[href*='/login']"));     } } 

mind you, using conductor framework. can translate css selectors had in there script.
