We can extract the column headers in a table in Selenium. The headers of a table are represented by tag in html and always in the first row of the table. The rows are identified with tag in html. A tag’s parent is always a tag.The logic is to get all the headers. We shall use the locator xpath and then use find_elements_by_xpath method. The list of headers will be returned. Next we need to compute the size of the list with the help of len method.Syntaxdriver.find_elements_by_xpath("//table/tbody/tr[1]/th")The html code snippet of a table header is as ... Read More

We can key in values inside an input text box with a Javascript executor in Selenium. Javascript is a language used for scripting and runs on the client side (on the browser). Selenium gives default methods to work with Javascript.SyntaxjavaScript = "document.getElementsByClassName('gsc-input')[0].value = 'T' ") driver.execute_script(javaScript)There are couple of methods by which Javascript can be executed within browser −Javascript execution at document root level.In this process, we shall identify the element with locators (class or id) and then perform the required action on it. Then execute_script() method is called and the Javascript is passed as a string to it.Syntax −javas ... Read More

We can perform click operation on links with Javascript executors in Selenium. Javascript is a language used for scripting and runs on the client side (on the browser). Selenium gives default methods to work with Javascript.SyntaxjavaScript = "document.getElementsByClassName('tp-logo')[0].click();" driver.execute_script(javaScript)There are couple of methods by which Javascript can be executed within browser −Javascript execution at document root level.In this process, we shall identify the element with locators (class or id) and then perform the required action on it. Then execute_script() method is called and the Javascript is passed as a string to it.Syntax −javas = "document.getElementsByName('user-search')[0].click();" driver.execute_script(javas)Please note, we have used ...

There are differences between current_window_handle and window_handles methods in Selenium. Both are methods to handle multiple windows. They differences are listed below −current_window_handleThis method fetches the handle of the present window. Thus it deals with the window in focus at the moment. It returns the window handle id as a string value.Syntax −driver.current_window_handlewindow_handlesThis method fetches all the handle ids of the windows that are currently open. The collection of window handle ids is returned as a set data structure.Syntax −driver.window_handles w = driver.window_handles[2]The above code gives the handle id of the second window open in the present session.ExampleCode Implementation with ...

There are differences between switch_to.parent_frame() and switch_to_default_content() in frames. They are listed below −switch_to_parent_frame()This method is used to come out of the present frame, then we can access the elements outside that frame and not inside of that frame. Thus the control is switched; the outer part may be another frame or part of the web page. So we are able to come out of the current frame.Syntax −driver.switch_to.parent_frame();switch_to_default_content()This method is used to come out of all the frames and switch the focus at the page. Once we move out, it loses the access to the elements inside the frames ... Read More

We can work with cookies in Selenium with the help of numerous methods which control the browser or its sessions. We can easily add or delete a cookie. A cookie implementation is essential for ensuring proper authentication of websites.The methods to work with cookie are listed below −add_cookie(args)This method adds a cookie to the present session. The arguments consist of the names of the cookies that we want to add.Syntax −driver.add_cookie({'id' : 'val' : 'session'})get_cookie(args)This method gets a cookie of a specific name. The argument consists of the name of the cookie that we want to retrieve.Syntax −driver.get_cookie("name")delete_cookie(args)This method deletes ... Read More

There are multiple exceptions available in Selenium that are thrown whenever any unexpected situations occur or any of the methods yield error. BaseException is the class from where all the objects of Python are derived.The exceptions that are generated by default are from the interpreter or the built in functions. The exceptions are generally created while we develop a new code and there is a good possibility of errors. Some of the exceptions of Selenium are listed below −ElementNotVisibleException – This exception is generated when an element is available in DOM, but it is invisible. Hence no actions can be ...

We can find the status of an element in a page with the help of Selenium. We can get the information if an element is enabled or disabled. Also, we can verify if an element is visible on screen for the user interaction or not.On a web page, there may be numerous checkboxes or radio buttons. Selenium provides a method to check if these UI elements are in a selected state or not.There are multiple methods to verify the status of an element. They are listed below −is_selected()This method verifies whether an element (checkbox, radio button) is in selected condition ... Read More

There may be situations when we need to open more than browsers with multiple tabs. In order to close these sessions quit() and close() methods are used in Selenium. However there are differences between them, they are listed below −The close() method can close the browser in focus. While quit() method works with the driver.dispose() method that closes every successive window.The close() method closes the present window on which we are working. While quit() method suspends all the driver sessions and instances, thereby closing each opened window.ExampleCode Implementation with close() method.from selenium import webdriver driver = webdriver.Chrome(executable_path="C:\chromedriver.exe") # to maximize ...

There are multiple common web driver methods that allow operation on browsers in Selenium with Python. Some of these methods are listed below −driver.get(url)This method is used to navigate or launch a new URL. The webdriver waits until there is full page load. For an application that has AJAX code, the web driver remains unaware about complete loading of the page. Thus for these situations we need to use waits.driver.maximize_window()This method is used to maximize the active window that is interacting with the web driver.driver.minimize_window()This method is used to minimize the active window that is interacting with the web driver.driver.back()This ...
