Selenium Waits

Waits are extremely important in Selenium. 

Selenium provides 3 wait types:

1. implicitwaits
2. explicitwaits
3. fluentwaits

Implicitwaits apply globally to every find element.

driver.manage().timeout().implicitwaits(30, TimeUnit.SECONDS);

Explicitwaits only apply per specific action or condition.

Explicit waits check the application every 500 ms to check for the condition of the wait to be true.

WebDriverWait wait = new WebDriverWait(driver, 60);
wait.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath(""));

Similar to explicit wait, fluentwaits only apply per specific action or condition.

Fluent waits require that you define the wait between checks of the application for an object or condition to be true and also the overall timeout of the transaction. In addition, you can tell fluent wait to not to throw an exception when it didnt find an object.

FluentWait wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(2, TimeUnit.SECONDS)
.ignoring(Exception.class);
WebElement el = wait.until(new Function<WebDriver, WebElement>(){
    public WebElement apply(WebDriver driver){
        return driver.findElement(By.xpath("");
    }});
