How to Sleep Selenium Webdriver in Python For Milliseconds

How to sleep Selenium WebDriver in Python for milliseconds

To suspend the execution of the webdriver for milliseconds you can pass number of seconds or floating point number of seconds as follows:

import time
time.sleep(1) #sleep for 1 sec
time.sleep(0.25) #sleep for 250 milliseconds

However while using Selenium and WebDriver for Automation using time.sleep(secs) without any specific condition to achieve defeats the purpose of Automation and should be avoided at any cost. As per the documentation:

time.sleep(secs) suspends the execution of the current thread for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time. The actual suspension time may be less than that requested because any caught signal will terminate the sleep() following execution of that signal’s catching routine. Also, the suspension time may be longer than requested by an arbitrary amount because of the scheduling of other activity in the system.

So as per the discussion instead of time.sleep(sec) you should use WebDriverWait() in-conjunction with expected_conditions() to validate an element's state and the three widely used expected_conditions are as follows:

presence_of_element_located

presence_of_element_located(locator) is defined as follows :

class selenium.webdriver.support.expected_conditions.presence_of_element_located(locator)

Parameter : locator - used to find the element returns the WebElement once it is located

Description : An expectation for checking that an element is present on the DOM of a page. This does not necessarily mean that the element is visible or interactable (i.e. clickable).

visibility_of_element_located

visibility_of_element_located(locator) is defined as follows :

class selenium.webdriver.support.expected_conditions.visibility_of_element_located(locator)

Parameter : locator -  used to find the element returns the WebElement once it is located and visible

Description : An expectation for checking that an element is present on the DOM of a page and visible. Visibility means that the element is not only displayed but also has a height and width that is greater than 0.

element_to_be_clickable

element_to_be_clickable(locator) is defined as follows :

class selenium.webdriver.support.expected_conditions.element_to_be_clickable(locator)

Parameter : locator - used to find the element returns the WebElement once it is visible, enabled and interactable (i.e. clickable).

Description : An Expectation for checking an element is visible, enabled and interactable such that you can click it.

Make Selenium wait 10 seconds

All the APIs you have mentioned is basically a timeout, so it's gonna wait until either some event happens or maximum time reached.

set_page_load_timeout - Sets the amount of time to wait for a page load to complete before throwing an error. If the timeout is negative, page loads can be indefinite.

implicitly_wait - Specifies the amount of time the driver should wait when searching for an element if it is not immediately present.

set_script_timeout - Sets the amount of time to wait for an asynchronous script to finish execution before throwing an error. If the timeout is negative, then the script will be allowed to run indefinitely.

for more information please visit following page. (documention is for JAVA binding, but functionality should be same for all the bindings)
https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/WebDriver.Timeouts.html#implicitlyWait-long-java.util.concurrent.TimeUnit-

So, if you want to wait selenium (or any script) 10 seconds, or whatever time. Then the best thing is to put that thread to sleep.

In python it would be

import time 
time.sleep(10)

In JAVA it would be

The simple way to do this is using

    try {
        Thread.sleep(10*1000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

How do I get my program to sleep for 50 milliseconds?

Use time.sleep()

from time import sleep
sleep(0.05)

Python Selenium: Wait until element is clickable - Element is found using find_elements

You need to take care of a couple of things here as follows:

As the searchBar element is a clickable element ideally you need you need to induce WebDriverWait for the element_to_be_clickable() as follows:
```
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "react-select-3-input"))).send_keys(address)
```
Again as the searchButton element is a clickable element you need you need to induce WebDriverWait for the element_to_be_clickable() as follows (in the worst case scenario assuming the searchButton gets enabled when search text is populated):
```
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CLASS_NAME, "sc-1mx0n6y-0"))).click()
```

Ideal dropdowns are html-select tags and ideally you should be using the Select class inducing WebDriverWait as follows:

Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "cssSelector_select_element")))).select_by_visible_text("visible_text")

Finally, the ID and CLASS_NAME values which you have used e.g. react-select-3-input, sc-1mx0n6y-0, css-19bqh2r, etc looks dynamic and may change when you would access the application afresh or in short intervals. So you may opt to lookout for some other static attributes.

Note: You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

How can I ask the Selenium-WebDriver to wait for few seconds in Java?

Well, there are two types of wait: explicit and implicit wait.
The idea of explicit wait is

WebDriverWait.until(condition-that-finds-the-element);

The concept of implicit wait is

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

You can get difference in details here.

In such situations I'd prefer using explicit wait (fluentWait in particular):

public WebElement fluentWait(final By locator) {
    Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
            .withTimeout(30, TimeUnit.SECONDS)
            .pollingEvery(5, TimeUnit.SECONDS)
            .ignoring(NoSuchElementException.class);

    WebElement foo = wait.until(new Function<WebDriver, WebElement>() {
        public WebElement apply(WebDriver driver) {
            return driver.findElement(locator);
        }
    });

    return  foo;
};

fluentWait function returns your found web element.
From the documentation on fluentWait:
An implementation of the Wait interface that may have its timeout and polling interval configured on the fly.
Each FluentWait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as NoSuchElementExceptions when searching for an element on the page.
Details you can get here

Usage of fluentWait in your case be the following:

WebElement textbox = fluentWait(By.id("textbox"));

This approach IMHO better as you do not know exactly how much time to wait and in polling interval you can set arbitrary timevalue which element presence will be verified through .
