How to reload the page if element doesn't appear in selenium webdriver java

At times due to time out or other reason the page stops loading or gets loaded but the signup page doesn't appear, to make sure it appears we have to refresh the page, I have tried driver.navigate.refresh(), I have tried explicit wait and javascript executor, nothing works, I am adding the snippet of what I have tried, but it doesn't work either.
My scripts fails once the findelement().isdisplayed is false, it is not going in the if loop.
Below is the code-
for(int i=0;i<3;i++)
{
System.out.println("In for loop");
try
{
if(driver.findElement(byusername).isDisplayed())
{
System.out.println("Element found");
driver.findElement(byusername).sendKeys(username);
driver.findElement(bypassword).sendKeys(password);
driver.findElement(signIn).click();
System.out.println("Logged in");
basewait.until( ExpectedConditions.presenceOfElementLocated(Tab));
System.out.println("Wait completed, going to base class");
i=3;
}
else
{
System.out.println("Element not found"+i+" try");
driver.navigate().refresh();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
i++;
}
}
catch(NoSuchElementException e)
{
System.out.println(e);
}

Try to replace:
if(driver.findElement(byusername).isDisplayed())
with:
if(driver.findElements(byusername).size() > 0 && driver.findElements(byusername).get(0).isDisplayed())
This won't throw exception and you can go to else statement. driver.findElements(byusername) return a list of elements found and if no elements were found it returns just an empty list.

First, note that an implicit wait only needs to be set one time, after the instantiation of your web driver, unless for whatever reason you wanted to later change the timeout value of that setting.
Second, try using the below code to wait for the page to finish loading.
/**
* Wait for the web page to finish loading
*/
public void waitForPageToLoad() {
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver wdriver) {
return ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("complete");
}
});
}

Selenium WebDriver not working fine on Amazon site

I am trying to write a Selenium test against Amazon site. I want to get "Sign in" element so that I can click on it.
url: www.amazon.es
Here is my Selenium Code:
System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.18.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.amazon.es");
try
{
driver.findElement(By.id("nav-link-accountList")).click();
}
catch (Exception e)
{
System.out.println("Not Found");
}
Sometimes the code works correctly but sometimes it does not find the ID "nav-link-yourAccount". What is the problem? and how can I solve it?

Provide few seconds of wait, before click to this webelement so your driver may able to find the webelement.
For wait i am using Explicit wait method.
WebDriverWait wait = new WebDriverWait(driver,10);
wait.until(ExpectedConditions.elementToBeClickable(driver.findElement(By.id("nav-link-accountList"))));
driver.findElement(By.id("nav-link-accountList")).click();

The element which you are trying to click with id as nav-link-yourAccount is not clickable. To proceed further you need to click either the link with text Hola. Identifícate or the link with text Mi cuenta using one of the following xpaths:
//a[#id='nav-link-yourAccount']/span[text()='Hola. Identifícate']
or
//a[#id="nav-link-yourAccount"]/span[contains(text(),'Mi cuenta')]

Instead using implicit wait try using explicit wait for the login element.
I've tried with explicit wait over 50 click and it did works.
Here is code you can use.
public class dump {
public static void main(String a[]){
System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.18.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
WebDriverWait wait = new WebDriverWait(driver, 15);
for(int i=0; i<=50; i++){
driver.get("https://www.amazon.es");
try{
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//*[#id='nav-link-accountList']")));
driver.findElement(By.xpath("//*[#id='nav-link-accountList']")).click();
System.out.println("clicked\t"+i);
}catch (Exception e){
e.printStackTrace();
System.out.println("Not Found");
}
}
}
}
Here is the proof of run:
All the best!!

Apply wait until element is appeared, so that it avoids NoSuchElementException and code is working without any error.
Below code is working fine:
driver.get("https://www.amazon.es");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
WebElement accontButton=driver.findElement(By.id("nav-link-accountList"));
WebDriverWait waitforelement=new WebDriverWait(driver,20);
waitforelement.until(ExpectedConditions.elementToBeClickable(accontButton));
try{
accontButton.click();
}
catch (Exception e){
System.out.println("Not Found");
}

Have you tried to find elements by xpath?
System.setProperty("webdriver.gecko.driver","C:\\geckodriver-v0.18.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.amazon.es");
try
{
driver.findElement(By.xpath("//*[#id='nav-link-accountList']")).click();
}catch (Exception e)
{
System.out.println("Not Found");
}

Explicit wait is not working if the element located is of 'text'

Explicit wait is not working if the element located is of 'text'. But it is working fine if the driver performs some action i.e, entering text into text box or clicking a webelement etc.
public boolean waitForPageToLoad(String timeOutInSeconds) throws ScreenShotException, InterruptedException {
boolean bFlag = false;
WebElement element;
boolean bStatus = true;
int timeinseconds1 = Integer.parseInt(timeOutInSeconds);
try {
WebDriverWait wait = new WebDriverWait(webDriver, timeinseconds1);
while(timeinseconds1 > 0) {
element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("myDynamicElement")));
Log.info("Element status at runtime -->"+element.isDisplayed());
if(!element.isDisplayed()) {
timeinseconds1 = timeinseconds1 - 500;
Thread.sleep(1000);
}
else {
System.out.println("working");
bFlag = bStatus;
Log.info("Element status: - >"+bFlag);
break;
}
}
}
catch (Exception e) {
screenShot.screenShot(e);
}
return bFlag;
}
The above code doesnt work if my locator is of text i.e, say if I want to check whether 'Title' of the question in the stackoverflow is visible or not within 40seconds.Driver will wait for 40seconds though the title appears less than that. But, it works fine if the locator is Title text box. Please let me know how to resolve this.

You are using the wait quite differently that it is supposed to be used.
try {
WebDriverWait wait = new WebDriverWait(webDriver, timeinseconds1);
element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("myDynamicElement")));
} catch (TimeOutException toe) {
//handle the page not loading
}
//from now on continue the code as synchronous knowing that the page is loaded

Continue Selenium Test instead of Timeout in WebDriverWait

i am using WebDriverWait in Selenium, i want to wait 10 second to wait if some Alert or Confirm box will appear, if it appears i will accept it. for example if confirm box ask me to "Leave Page" or "Stay on Page" then i want to leave page automatically, and if alert is not appeared in 10 seconds then continue code Excecution instead of throwing Exception. or you can tell me some way to accept All confirm, alert boxes automatically during whole selenium test. thanks
here is my code
WebDriver driver = new FirefoxDriver();
driver.get("https:www.google.com");
WebDriverWait wait = new WebDriverWait(driver, 10 );
if(wait.until(ExpectedConditions.alertIsPresent())==null)
{
System.out.println("alert was not present");}
else{
Alert alert = driver.switchTo().alert();
alert.accept();
System.out.println("alert was present");}

try/catch is useful to catch/handle the exception. Just place alert code in try block, if any exception occurs, it will handle in catch block and there after execution will continue..
WebDriver driver = new FirefoxDriver();
driver.get("https:www.google.com");
WebDriverWait wait = new WebDriverWait(driver, 5 );
try{
if(wait.until(ExpectedConditions.alertIsPresent())==null)
{
System.out.println("alert was not present");
}else{
Alert alert = driver.switchTo().alert();
alert.accept();
System.out.println("alert was present");
}
}catch(Exception e){
System.out.println("ignored alret not present exception" +e.getMessage());
}
}
Thanks

java: Sleep until website is fully loaded

I want to open a website with selenium and extract some text via xpath. It's working but I can get the text only if I wait a few seconds until the whole website is loaded, but it would be nicer to check if the website is fully loaded. I guess I should check for any background connections (ajax calls, GETs, POSTs or whatever), what is the best way to do it? At the moment I'm trying to extract the text in a while loop (ugly solution):
WebDriver driver = new FirefoxDriver();
driver.get("http://www.website.com");
// Try to get text
while (true) {
try {
WebElement findElement = driver.findElement(By.xpath("expression-here"));
System.out.println(findElement.getText());
break;
// If there is no text sleep one second and try again
} catch (org.openqa.selenium.NoSuchElementException e) {
System.out.println("Waiting...");
Thread.sleep(1000);
}
}
How would you solve this?

Selenium has already timeouts for this.
Look here: http://seleniumhq.org/docs/04_webdriver_advanced.jsp
I have solve it with:
webDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

Prefer explicit waits:
1) more readable
2) been using those for long time
3) what if you know the element is not there (your test is to verify it) and don't need to poll for 10 seconds? With implicit you are now wasting time.
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(new ExpectedCondition<WebElement>(){
#Override
public WebElement apply(WebDriver d) {
return d.findElement(By.id("myDynamicElement"));
}});
