Testing logout with selenium

Hi im new to selenium and i have to test if user can logout from page, heres my method for testing it, but unfortunately it doesnt never gets to the page, i think im missing something in the method :

public boolean logOut() {
    WebDriver driver = getDriver();
    //driver.get(BASE_URL);
    driver.get("http://ift.tt/1yrHtPf");
    elementById("log_out_link").click();

    if(!driver.getCurrentUrl().equals("http://ift.tt/1yrHtPl"))
    {
        return false;
    }

    return true;
}

Heres the test if user returns to the main page it should return true so the test will pass but it always returns false:

 @Test
public void logOutSuccess() {
    LoginPage loginPage = LoginPage.goTo();
    loginPage.logInWith(USERNAME, CORRECT_PASSWORD);
    System.out.println(driver.getPageSource());
    assertThat(loginPage.logOut(), is(true));
}
