Python will start and control the chromium browser using the code below:

The driver вЂњChromeDriverвЂќ is needed to start Chrome, вЂњFirefoxDriverвЂќ for Firefox. To start a browser, you will need to corresponding web driver. Python interacts with the selenium web driver and the web driver interacts with the browser. To start a web browser, the Selenium module needs a web driver. If you are new to selenium and browser automation, I recommend the course below.Д«rowser Automation with Python Selenium Web Driver Because Selenium starts a webbrowser, it can do any task you would normally do on the web. For instance, lets change poll frequency to 1 second.Selenium is a web automation framework that can be used to automate website testing. We have the option to change the poll frequency by passing keyword argument вЂpoll_frequencyвЂ™ which accepts values in seconds. A successful return is for ExpectedCondition type is Boolean return true or not null return value for all other ExpectedCondition types. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds, which is called poll frequency, until it returns successfully. Men_menu = wait.until(ec.visibility_of_element_located((By.XPATH, wait for Fastrack menu item to appear, then click itДЇastrack = WebDriverWait(driver, 10).until(ec.visibility_of_element_located((By.XPATH, waits up to 10 seconds before throwing a TimeoutException unless it finds the element to return within 10 seconds. # wait for element to appear, then hover it WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.ДЇollowing two packages are required to set explicit waitДЇrom import WebDriverWaitДЇrom import expected_conditions as ecДЇrom _chains import ActionChainsДЇrom import By There are some predefined methods provided that will help your script to wait only as long as required. To avoid that situation explicit wait is used by defining a separate wait time only on the required element. In that case no need to set a huge time to Implicit wait, as this will make browser to wait for the same time for every element. There can be instance when a particular element takes more than usual time to load. Here we define to wait for a certain condition to occur before proceeding further in the code. Pass number of seconds to wait as an argumentДriver.get(' driver.find_element_by_id('id_of_element').click()Д®xplicit wait is used to specify wait condition for a particular element. all actions will be delayed by given time.

Once set, the implicit wait is set for the life of the WebDriver object i.e. The default setting is 0 seconds which means WebDriver will not wait before any operations on element. Wait provides some time interval between actions performed like locating element or any other operation with the element.ДЄn implicit wait instructs Selenium WebDriver to poll DOM for a certain amount of time, this time can be specified, when trying to find an element or elements that are not available immediately. Using waits, we can wait for an element to be available in DOM. At the same time, this delay should not make test script execution longer.

There should be some kind of delay to wait for these elements.

This makes locating elements difficult if the element Selenium looking for is not present in the DOM, it will raise NoSuchElementException exception. In modern applications, elements within the page may load at different time intervals even after page is loaded.

AJAX is still loading and element will be created after AJAX.

Element to interact with is not available in DOM yet.

Reasons could be many, including but not limited to below. However most of the user action requires some kind of wait before performing it. User actions could be click, select, type etc. We all know and experimented that Selenium WebDriver can interact with web browser and simulate user actions.
