All you need to know to automate web-based tests and processes

Customer interaction is increasingly happening online, websites and web applications are crucial to generating revenue, and several traditional front- and back-office applications are migrated from desktops to web-based interfaces or the cloud. This transformation creates a technology dependency, and to lower costs and mitigate risk, businesses face an urgent need for automating web-based tests and processes.

Section-1-1 What is
Web Automation?


Web automation is the concept of letting software robots perform actions, tasks, and processes that involves a web browser or web application.


What can you do with web automation?

Think of all the clicking and typing you do at your desk everyday that involve websites and web-based applications. All these actions can be automated with web automation. Examples of tasks include (inspired by Hacker Noon):

  • Filling out forms and fields

  • Scraping content from a web page

  • Extracting and transferring data between applications

  • Functional testing of websites and web applications across browsers and devices

  • And much more

Every day, in businesses of all sizes, there are scenarios where automating tasks like these would come in handy. For example: Importing contacts into a CRM system from a third-party service, testing the user experience and order handling of an online shop, integrating a web-based ERP-system with a document management platform in the cloud, and so on.


What is Selenium browser automation?

When talking about web automation, there is no way around Selenium, the world’s most popular open-source framework for automating browsers. It consists of several components, but here we will cover the widely used Selenium WebDriver. All components of the Selenium suite, are open-source tools for automation of websites and web applications.

WebDriver is an API that can automate any action that takes place in a web browser. It drives browser actions natively, meaning that it interacts with browser elements, like clicking on buttons, typing text in fields, etc., like a real user would.

Selenium WebDriver is operated by writing code in one of several common programming languages (C#, JavaScript, PHP, Python, etc.)

Creating a Selenium script is a 7-step process as described in SauceLabs’ Selenium introduction:


Group 10096


Below is an example of how a Selenium test script can look like. In this case, the WebDriver is instructed to:

  • open a Chrome browser;

  • navigate to the web page amazon.com;

  • input the term “Lego” in a search field;

  • wait for the page to load results;

  • click on one of the items in the search results, and then;

  • conclude the test case by verifying the presence of a specified image.


Group 10097


As illustrated by this case, a considerable amount of programming proficiency is required to understand, let alone create, a relatively simple script.

The other widely used component of the Selenium products is Selenium Grid.


What is Selenium browser automation?

Selenium is one of the most widely used frameworks for web automation, with good reason. The software’s strengths include (Source: Guru99):

  • Open source, free to use, and free of charge

  • Highly extensible

  • Can run cases across different browsers

  • Supports various operating systems

  • Supports mobile devices

  • Can execute cases while the browser is minimized

  • Can execute cases in parallel

Selenium vs. LEAPWORK



Selenium WebDriver does come with some serious limitations (see table below), when used as a stand-alone tool. Instead, by using a fully-featured automation tool which has incorporated the WebDriver in its technology, like the LEAPWORK Automation Platform, you can enjoy the advantages of WebDriver without having to worry about the tool’s weakness:

See the video below for how a Selenium-based web automation case is built without writing scripts:


Section-1-2-1 How to Build
Web Automation?


Web-based tasks and processes can be broken down into three overall types of actions:

  • Operating browsers to navigate the web

  • Interacting with web elements, both static and dynamic elements

  • Inputting/outputting data, text, and numbers

In theory, that’s all you need to know to start building automated processes involving websites and web applications.


Web automation with Selenium-powered building blocks

Imagine if each action and operation listed above was a building block that you could connect to make up visual workflows representing web-based processes. That’s the idea behind LEAPWORK’s Selenium-powered web automation blocks.

The example below automates the following process: Search for an item (“star wars lego”) in an online shop (amazon.com) and then compare the number of search results with a specified value (2500).


Aktiv 234


The automation flow outlined in this example is created by connecting just seven commands, or building blocks:


Group 10101


This approach of using visual building blocks to design processes enables automation of practically any web application and websites in any of the common browsers: Google Chrome, Mozilla Firefox, Microsoft Edge, and Internet Explorer.



Common web-based operations and functionalities to automate

As mentioned above, all web-based tasks and processes involve operating browsers, interacting with web elements, and inputting or outputting data. Examples include: typing credentials into an authentication form, dragging and dropping elements on a web page, uploading a file to a web application, etc. Some operations are more challenging than others to automate – at least, it requires a few more configurations to make a robot perform the operation correctly.

For example, with the LEAPWORK automation blocks, to find a specific image on a web page, you just need a simple “Find Web Element” operation, but to verify an ‘infinite scroll’ functionality on a web page you need to do a minor configuration of the same operation and then customize the strategy for locating a specific element. However, you can still instruct a LEAPWORK robot to perform even this slightly more complex example without having to write a single line of code.

Now that we have covered the ‘bricks’ that make up web automation, let’s look of how web automation is being used in different organizations to solve various challenges.

Section-1-3-1 Web Automation
Use Cases


Web automation is applicable to processes involving any website and web application, both external and internal. Below are some real-life examples of how organizations are benefiting from web automation.


Automating ticket creation and service desk requests

At a major utility company managing critical infrastructure for energy and gas, all service desk requests are managed with ServiceNow, a web-based business process platform.

ServiceNow is a great example of an application that can be automated with the codeless, Selenium-based automation approach outlined above.



Utilizing web automation, the IT Process Team at the utility company could automate the testing of business flows going across functions and departments involving multiple applications, including ServiceNow. This has allowed them to significantly reduce the time spent on testing in relation to system upgrades. This freed up time was then allocated to business-critical tasks, like customer support.


More frequent system upgrades + Earlier
fixing of system bugs + Security risks reduced
= Better Customer Experience.


Automation of industry-specific back-office systems

Back-office functions are increasingly being handled with web-based applications – even industry-specific ones, like Policy Management Systems (PMS) in the insurance sector and Transport Management Systems (TMS) at logistics companies. From an automation perspective, this move to web-based technologies simplifies things: Any application that can be operated using a web browser, can be automated with the approach described in this guide.

For example, an insurance company moved from quarterly to monthly releases of their policy management system, by automating the testing of the system based on the web application Pega.

Another example: a global logistics company automated their web-based online booking system which integrates with their TMS, reducing weeks of workload to the few clicks required to instruct robots to perform repetitive tasks.



E-commerce automation

E-commerce is practically an inevitable part of selling and purchasing products and services today: Digital and mobile storefronts, electronic transfer of funds, web-based inventory systems, and online marketing are just a few of the different aspects of e-commerce.

Automating front- and back-end processes for monitoring and testing purposes can help enhance the robustness and quality of an e-commerce channel. This involves:

  • ensuring availability of an online shop from an end-user perspective

  • continuous monitoring of the operational status of the entire channel

Automating CRM workflows

CRM systems have great automation potential: They are used for processes that go across departments and functions, they are often web-based, and a lot of the tasks involved are repetitive.

Salesforce, for example, is a top tier CRM solution for enterprises and organizations with popular cloud services for managing sales, marketing, help desk requests and much more. It's highly customizable and can be configured and extended to fit almost any requirement. The size and complexity of Salesforce means that many repeatable tasks are performed manually by sales reps, marketeers and managers over and over every day.

Automating intranets and extranets

Web automation is not only for public systems. For example, a global manufacturer of medical devices automated a SharePoint-based service portal monitoring devices and systems at thousands of hospitals worldwide.



How to drive web automation with data?

Web-based automation flows often involve repetitively inputting data, e.g. to fill out a form several times. There are several ways to input data to automation flows, either by using static data sources, like spreadsheets, or dynamic sources, like databases, web services, and command shells.

Web Automation


When it comes to executing web automation flows, there are two major concepts you need to know about:

  • Hosted environments: Execute automation flows across devices and systems using cloud-based services.

  • Parallelization: Run automation flows on several machines in parallel


How to set up hosted environments for automated web testing?

To deliver a great end-user experience, web applications and websites must work across multiple browsers, browser versions, operating systems, and devices, including mobile. With all the possible combinations, the number of usage scenarios to be tested explodes! One provider of hosted environments for automated web testing, Sauce Labs, have identified more than 2,000 devices and more than 800 browser-OS combinations – and those are just the most commonly used.

From a testing perspective, a major challenge presents itself: Is it necessary for your organization to host all the possible combinations of browsers, operating systems, and devices in your own infrastructure to support automated web testing? This would come with additional costs and a massive administrative burden negatively impacting the business case for test automation.

Fortunately, you can outsource the hosting of test environments to vendors such as BrowserStack and Sauce Labs.

What follows is a walk-through of how to use hosted environments for web automation. Besides access to a provider of hosted environments such as setup only requires a few things: A suite of automated test cases ready to be executed, and a service running the test cases, called the Controller.


Group 10107



Group 10108


With this setup, a test team does not have to worry about preparing and maintaining the machines and devices on which the test cases are executed. For example, it is not necessary to purchase, maintain, and charging a bunch of different mobile devices.




Parallelization of Web Automation

Besides using environments hosted by cloud-based providers as described above, there are other ways to parallelize web automation, including execution agents and Selenium Grid.


Execution Agents – on local, remote, or virtual machines

An execution agent is a piece of software that is installed on every machine where automation cases are to run. Agents allow for a great deal of flexibility, as they can execute automation commands on both local, remote, and virtual machines. Agents can be installed in different and separate environments, including cloud servers, allowing for collaboration across teams and even across organizations, for example if you work with an automation partner.


Selenium Grid

Selenium Grid is a server for setting up different environments in which automation cases are executed. It is based on a Hub-Node concept and can be set up in your own infrastructure.


Group 10110


The Hub is the central machine running the automation cases, and the Nodes are different machines on which the actual browser automation takes place. The advantage of Selenium Grid is the ability to run multiple cases in parallel across different browsers, operating systems, and machines.




The different options for parallelizing web automation with LEAPWORK are illustrated below. The LEAPWORK Controller is the test runner service, and LEAPWORK Studio is where users design their automated test cases. Learn more about the different deployment options with LEAPWORK.
