How to get Correct url using Selenium Webdriver

Question

I have written selenium webdriver test and want o test back and forward options of browser. My code is

@Test
    public void testBrowserHistory() throws Exception
    {
        //Load web page
        d.navigate().to("http://docs.seleniumhq.org/");
        assertEquals("Selenium - Web Browser Automation",d.getTitle());
        //Click on Download Tab
        d.findElement(By.linkText("Download")).click();
        System.out.println(d.getCurrentUrl());
        d.navigate().back();
        System.out.println(d.getCurrentUrl());
        d.navigate().forward();
        System.out.println(d.getCurrentUrl());
        d.navigate().refresh();
        System.out.println(d.getCurrentUrl());
    }
    @Before
    public void setUp()
    {
        //Launch browser
        System.setProperty("webdriver.gecko.driver", "C://Selenium driver/geckodriver.exe");
        DesiredCapabilities capabilities = DesiredCapabilities.firefox();
        capabilities.setCapability("marionette", true);
        d=new FirefoxDriver();
        d.manage().timeouts().implicitlyWait(60,TimeUnit.SECONDS);
        d.manage().deleteAllCookies();
    }
    @After
    public void tearDown()
    {
        //Close browser
        d.quit();
    }

}

The output is

http://docs.seleniumhq.org/
http://docs.seleniumhq.org/
http://docs.seleniumhq.org/

The browser does not go to download page. What is the problem.

Answer 1

After clicking on Download button, wait for Download page to appear. 

You can wait for title of the Download page to make sure that Download page is loaded.

WebDriverWait wait = new WebDriverWait(d, 15);
wait.until(ExpectedConditions.titleIs("Downloads"));

Then do 

System.out.println(d.getCurrentUrl());
 

Also, see if 

d.findElement(By.linkText("Download")).click();

is working. If not, you can try using xpath: 

//*[@id="menu_download"]/a
