How To Handle Tabs in Selenium? A Complete Guide

Modern web applications oft open links in new tabs. Sometimes, your test script postulate to switch between them to complete a user journeying or validate a feature.

Selenium lets you control tabs just like windows. You can open a new tab, swap focus, fold it, and return to the original one. Once you know how to handle multiple tabs in Selenium, your test coverage improves dramatically.

In this guide, we ’ ll show you:

• How to open and close browser tabs during test runs
• How to switch between tabloid and manage tab handles
• Mutual issues when working with multiple tabloid
• Best exercise to treat multiple tabs in Selenium without confusion

Let ’ s get started.

How to Open a New Tab in Selenium?

Selenium does not include a built-in function for opening new tabs, but you can notwithstanding do it pretty easily by using key commands or JavaScript. Each access works well in different test surround.

Here 's how to open a new tab in three ways:

1. Open a new tab with keyboard shortcut (Windows or Linux)

This method sends the control key and `` t '' to the browser window. It open a white new tab.

from selenium.webdriver.common.keys import Keys driver.find_element (`` tag gens '', `` body '') .send_keys (Keys.CONTROL + `` t '')

2. Open a new tab with keyboard shortcut (Mac)

For macOS users, you ’ ll use the Command key instead. The outcome is the like: a fresh tab opens in the same browser window.

driver.find_element (`` tag name '', `` body '') .send_keys (Keys.COMMAND + `` t '')

3. Open a new tab with JavaScript

JavaScript gives you direct control. You can open a tab and burden a specific URL right off. This is the most dependable option when you want to test multiple flows across tabs.

driver.execute_script (`` window.open ('https: //katalon.com ', '_blank '); '')

All three method help you start handle tabs in Selenium with confidence.

How to close tab in Selenium?

Once you know how to open a new tab, the next step is learning how to close it properly.

Selenium gives you two bidding for this:

• Use driver.close ()to shut the current tab
• Use driver.quit ()to end the entire session.

Make sure to always track which one you 're on. Closing the wrong tab can separate the test flow. You require to switch to the target tab, close it, then return to the original.

This handwriting shows how to open two tabs, closely the second one, and go back to the first:

SUSA automates exploratory testing with persona-driven behavior, catching bugs that scripted automation misses.

driver.get (`` https: //katalon.com '') original_tab = driver.current_window_handle driver.execute_script (`` window.open ('https: //example.com ', '_blank '); '') tabs = driver.window_handles driver.switch_to.window (tabs [1]) driver.close () driver.switch_to.window (original_tab)

This flow works well when your test needs to corroborate demeanour across tabs. It also avoids fault by get sure you ’ re always closing the right one.

How to deal multiple tabs in Selenium?

Selenium handles browser tabs through a built-in property calledwindow_handles. This give you a list of all open tabs at any point during your test. You can use that leaning to switch tab, perform actions, and move focussing as needed.

Once you get the tab manage, you can amply control the browser flow from one step to the next.

Let ’ s look at a complete example:

driver.get (`` https: //katalon.com '') driver.execute_script (`` window.open ('https: //example.com ', '_blank '); '') driver.execute_script (`` window.open ('https: //www.google.com ', '_blank '); '') tabs = driver.window_handles # Switch to second tab and print the rubric driver.switch_to.window (tabs [1]) print (driver.title) # Switch to third tab and print the title driver.switch_to.window (tabs [2]) mark (driver.title) # Return to first tab driver.switch_to.window (tabs [0])

This pattern give you full control across tabs. You can switch focus, interact with elements, validate content, and more. The key is cognize when and where to hold the switch.

Handling multiple tabs utilise Window Handler

Selenium useswindow_handlesto keep track of every open browser tab. It stores them in the order they were open. You can use this list to loop through each tab, switch between them, and perform validations like ensure the page title.

You also have admittance to the current tab withcurrent_window_handle. This is useful when you want to return to your starting point after navigate across tabs.

This model opens a few tab and publish the title of each one:

driver.get (`` https: //katalon.com '') driver.execute_script (`` window.open ('https: //example.com ', '_blank '); '') driver.execute_script (`` window.open ('https: //google.com ', '_blank '); '') tabs = driver.window_handles original_tab = driver.current_window_handle for index, tab in enumerate (tabs): driver.switch_to.window (tab) print (f '' Tab {index + 1} Title: '', driver.title) driver.switch_to.window (original_tab)

This grommet gives you full visibility into each tab 's content. It also keeps your examination organized by retrovert focus to the original tab.

Switching window or tab in Selenium

Selenium expend the like API to handle both browser windows and tabs. This integrated coming makes it leisurely to switch between different view during a trial, whether it ’ s a login page, a new feature walkthrough, or a third-party consolidation window.

To switch between tabs or windows, Selenium render thewindow_handleslist and theswitch_to.window ()method. You can store the handle of your current tab, move to the new one, and so switch back when needed. This helps see stability in workflows that depend on tab circumstance.

Here ’ s a simple use case:

• Store the current tab as the main app tab.
• Open a new tab for user login or third-party interaction.
• Switch back to the main tab after the process finish.

from selenium import webdriver meaning time driver = webdriver.Chrome () driver.get (`` https: //katalon.com '') # Save the current window handle main_tab = driver.current_window_handle # Open a new tab driver.execute_script (`` window.open ('https: //example.com ', '_blank '); '') time.sleep (2) # Switch to the new tab new_tab = driver.window_handles [1] driver.switch_to.window (new_tab) print (`` New tab rubric: '', driver.title) # Switch backward to the primary tab driver.switch_to.window (main_tab) mark (`` Back to main tab title: '', driver.title)

Common issues when handling tabs in Selenium

Working with browser tabs is smooth when you follow a few key checks. These mutual scenarios will facilitate you avoid surprise and handle Selenium tabs with more control and lucidness.

• Sometimes Selenium opens a new tab but doesn ’ t detect it right away. You can use an explicit wait to pause until the number of tabs meets your expectation. This afford the new tab time to load.
• If the tab is fold too presently, trying to swop to it may make aNoSuchWindowException. You can forfend this by assure the grip listing before switching.
• Switching between tabs might change the circumstance of your elements. If your test throws a stale element error, the best way is to re-locate the component erst you ’ re in the right tab.

Here are a few quick tips:

• Always await for the new tab withWebDriverWait and number_of_windows_to_be ().
• Check if the grip exists inwindow_handlesbefore switching.
• Use driver.find_element ()again after switching to control your element is tonic.
• Store the original tab handle at the beginning so you can return to it easily.

Best practices for handling tabs in Selenium

If you 're memorize how to handle multiple tabs in Selenium, it ’ s helpful to postdate a few tried habits:

• Always preserve the original tab handle before launching new ones. This lets you arrive backwards to your starting point at any time with entire control.
• New tabs might not be ready correct forth. Useexplicit postponementto make sure the page full charge before you interact with it.
• Wrap your tab-switching logic into helper functions. This keeps your code little, clear, and easy to recycle across test cases.
• Closing tabs you no longer use keeps the session jackanapes and focused. It helps reduce memory usage and prevents confusion when looping through multiple handles.
• Handling multiple tab in Selenium becomes much mere when your code is clean and your delay are easily placed. Each step builds confidence into your automation flowing.
