WebDriver can also manage testing across multiple windows, tabs and webpages in a single test session. If you haven't already, install Microsoft Edge Chromium from this page. WebDriver needs a browser-specific driver to automate each browser. Having the correct version of WebDriver for your build ensures it runs correctly. The build number for Microsoft Edge Canary on January 14, Now, download the matching version of Microsoft Edge Driver from this page. The Downloads section of the Microsoft Edge Driver page.
The last component you need to download is a language-specific client driver. Download the WebDriver language binding of your choice. We highly recommend Selenium 4. However, you are able to drive Microsoft Edge Chromium in all earlier versions of Selenium, including the current stable Selenium 3 release. You can install the. NET language binding of Selenium 4. You must manually create EdgeDriverService as shown in the C snippet above.
If you have downloaded a Selenium language binding that is v4. This is a breaking change and Microsoft Edge Chromium no longer accepts these commands. If you are using Chocolatey as your package manager, you can also get Microsoft Edge Driver by running this command:.Extending SeleniumLibrary. SeleniumLibrary is a web testing library for Robot Framework that utilizes the Selenium tool internally. SeleniumLibrary works with Selenium 3. It supports Python 2. In addition to the normal Python interpreter, it works also with PyPy and Jython.
Unfortunately Selenium is not currently supported by IronPython and thus this library does not work with IronPython either. SeleniumLibrary is based on the old SeleniumLibrary that was forked to Selenium2Library and then later renamed back to SeleniumLibrary. See the Versions and History sections below for more information about different versions and the overall project history.
Working with Selenium on VBA
See keyword documentation for available keywords and more information about the library in general. The recommended installation method is using pip :. Running this command installs also the latest Selenium and Robot Framework versions, but you still need to install browser drivers separately. The --upgrade option can be omitted when installing the library for the first time.
The above command installs the normal SeleniumLibrary as well as a new Selenium2Library version that is just a thin wrapper to SeleniumLibrary. That allows importing Selenium2Library in tests while migrating to SeleniumLibrary. To install the last legacy Selenium2Library version, use this command instead:. With resent versions of pip it is possible to install directly from the GitHub repository.
To install latest source from the master branch, use this command:. Please note that installation will take some time, because pip will clone the SeleniumLibrary project to a temporary directory and then perform the installation.
See Robot Framework installation instructions for detailed information about installing Python and Robot Framework itself. For more details about using pip see its own documentation. After installing the library, you still need to install browser and operating system specific browser drivers for all those browsers you want to use in tests. These are the exact same drivers you need to use with Selenium also when not using SeleniumLibrary. More information about drivers can be found from Selenium documentation.
The general approach to install a browser driver is downloading a right driver, such as chromedriver for Chrome, and placing it into a directory that is in PATH. Drivers for different browsers can be found via Selenium documentation or by using your favorite search engine with a search term like selenium chrome browser driver. New browser driver versions are released to support features in new browsers, fix bug, or otherwise, and you need to keep an eye on them to know when to update drivers you use.
To use SeleniumLibrary in Robot Framework tests, the library needs to first be imported using the Library setting as any other library. The library accepts some import time arguments, which are documented in the keyword documentation along with all the keywords provided by the library.
When using Robot Framework, it is generally recommended to write as easy-to-understand tests as possible. The keywords provided by SeleniumLibrary are pretty low level, though, and often require implementation specific arguments like element locators to be passed as arguments.Selenium can be classified as the automation tool that facilitates scraping of information from the HTML web pages to perform web scraping utilizing google chrome.
In this tutorial, you will learn: What is Data Scraping using selenium? There are certain prerequisites that has to be performed on the excel macro file before getting into the process of data scraping in excel. These prerequisites are as follows: - Step 1 Open an Excel-based Macro and access the developer option of excel.
Step 2 Select Visual Basic option under Developer ribbon. Step 3 Insert a new module. Step 4 Initialize a new subroutine and name it as test2. Sub test2 End sub Following would be the results in the module: - Step 5 Access the reference option under the tool tab and reference Selenium type library. The following libraries are to be referenced to the module as it helps in opening google chrome and facilitates the development of macro scripting.
Now the Excel file is ready to interact with the internet explorer. Next steps would be to incorporate a macro script that would facilitate data scraping in HTML. The following would be the code. Sub test2 Dim driver as new webdriver Dim rowc, cc, columnC as integer Driver. Once you are able to access the google chrome using VBA, the next step would be to incorporate the accessing of a website using VBA.
This facilitated by get function wherein the URL has to pass as double quotes in the attribute. Follow the following steps as displayed The module would look as follows: - Press F5 to execute the macro. The following webpage would be opened in google chrome as displayed Sub test2 Dim driver as new webdriver Dim rowc, cc, columnC as integer Driver.
The next step would display how the information can be extracted by applying selenium and VBA. Suppose the day trader wants to access the data from the website on a daily basis. Each time the day trader presses the click the button, it should auto pull the market data into excel. From the above website, it would be necessary to inspect an element and observe how the data is structured. Therefore, in order to pull entire data from the HTML table, it would require designing of macro which pulls the header information of the HTML table and the corresponding data associated with the table.
Perform the following tasks as displayed: - Step 1 Formulate a for loop that runs through the HTML header information as a collection.
The selenium driver has to find the header information of the HTML table. Start "chrome" driver. FindElementByClass "dataTable". FindElementByTag "thead". FindElementsByTag "th" Sheet2. Cells 1, cc. FindElementByTag "tbody". FindElementsByTag "td" Sheet2. Cells rowc, columnC. To reduce the complexity of the VBA script, the collection data is initialized to the excel cells attribute of the sheet 2 present in the workbook.
Further, the text attribute helps in getting the text information placed under HTML tag. Label the button as refresh or any suitable name that could be initialized to it. For this example, the button is initialized as refresh.The python which you are running should have the selenium module installed.
The selenium. The driver. A detailed explanation of finding elements is available in the Locating Elements chapter:. Next, we are sending keys, this is similar to entering keys using your keyboard. Special keys can be sent using Keys class imported from selenium. After submission of the page, you should get the result if there is any. To ensure that some results are found, make an assertion:. Finally, the browser window is closed.
You can also call quit method instead of close. Selenium is mostly used for writing test cases. In this chapter, we use unittest as the framework of choice. Here is the modified example which uses unittest module. This is a test for python. Initially, all the basic modules required are imported. This module provides the framework for organizing the test cases. The test case class is inherited from unittest. Inheriting from TestCase class is the way to tell unittest module that this is a test case:.
The setUp is part of initialization, this method will get called before every test function which you are going to write in this test case class. Here you are creating the instance of Firefox WebDriver. This is the test case method. The test case method should always start with characters test. The first line inside this method create a local reference to the driver object created in setUp method.
Detailed explanation of finding elements is available in the Locating Elements chapter:. Special keys can be send using Keys class imported from selenium. After submission of the page, you should get the result as per search if there is any. The tearDown method will get called after every test method.This reference is for experienced Office users who want to learn about VBA and who want some insight into how programming can help them to customize Office.
The Office suite of applications has a full set of features. There are many different ways to author, format, and manipulate documents, email, databases, forms, spreadsheets, and presentations.
The great power of VBA programming in Office is that nearly every operation that you can perform with a mouse, keyboard, or a dialog box can also be automated by using VBA. Further, if it can be done once with VBA, it can be done just as easily a hundred times. In fact, the automation of repetitive tasks is one of the most common uses of VBA in Office.
Beyond the power of scripting VBA to accelerate every-day tasks, you can use VBA to add new functionality to Office applications or to prompt and interact with the user of your documents in ways that are specific to your business needs. For example, you could write some VBA code that displays a pop up message that reminds users to save a document to a particular network drive the first time they try to save it.

I am not familiar with selenium, after trying a lot of times I finally come out below clunky codes. Why that I have to add selenium.
SwitchToNextWindow after opening new tab, or the next url will be opened on the original tab, not new tab? But if I run the codes line by line in debugging environment, all 10 urls can be successfully opened.
Why's that? I googled that if I want chrome not to exit after finishing running macro, I have to declare object selenium outside the sub though I do not quite get the reason. Could anyone help explain me in plain way? If any experts can help me optimize my codes, that would be much appreciated! The context of the driver remains the same when a new window is opened. You have to explicitly tell the driver that you want to operate on another window.
Probably because some of the memory is released once the page is fully loaded. But since you are loading all the pages in a row, it may not leave the browser enough time to manage it's memory.
Selenium automates browsers. That's it!
I would try to disable the plugins if any especially Flash and add some waiting:. The driver is automatically terminated once the variable holding the driver is no longer used. So to keep the driver alive outside of a procedure, it must be declared outside:.

When I tried to run the code from last year, I get an error on the line:. I've read several posts about versions of chrome and chromedriver. I've downloaded what I think it the newest Selenium driver and chromedriver.
I'm what I should be installing for Selenium and ChromeDriver. Anyone have any step by step they can help me with? Or other suggestions about what's causing my error? Hi GordonPrince. I find that when you update the web browser then you need to update this web driver with latest version.
