Technology, in recent days, has reached the peaks and the growth of automation has added more wings to this transformation. From automating a simple unit test to automating the whole business process, technology has augmented its way to the digital era. In this Selenium vs RPA blog, I will give you a lucid idea of how these automation tools differ from one another. You can refer to the Selenium Training for further details.
Following are a few stats that reflect the growth in the demand of automation quite accurately:
- According to house of bots, the market of RPA is estimated to reach $2.46 billion by 2024, at a CAGR of 30.14% between 2017 and 2024. This is directly proportional to the people trying to build a career in RPA.
According to prnewswire, the global automation testing market size is expected to grow from USD 8.52 billion in 2018 to USD 19.27 billion by 2024, at a CAGR of 17.7% during the forecast period. Selenium is one of the most used automation testing tools.
So, in this Selenium vs RPA blog, I will be comparing the two automation giants. Let’s take a look at what we will be discussing in this Selenium vs RPA blog:
- What is Selenium? What are its features?
- What is RPA? What are its features?
- Comparison of Selenium and RPA
- Conclusion
Before comparing Selenium & RPA, let us know each one of them in detail.
Selenium vs RPA: What is Selenium? What are its features?
- Selenium supports cross-browser testing which makes the implementation of the test-cases easy across various browsers multiple times.
- Test cases can be written in several programming languages such as Java, Python, C#, Ruby, etc. Among these, Java is the most commonly used language to write test scripts.
- Selenium is highly flexible when it comes to functional and regression testing. Functional testing helps to test the software against the business requirement and ensures there are no defects. Regression testing helps in re-executing the tests against the modified application to checks whether the modified code runs accordingly.
- A set of Selenium commands that run tests are called Selenese, and test script refers to the sequence of these commands.
- Tests cannot be performed on mobile or desktop applications; it is solely prone to web application testing.

Let us talk about one of the scenarios where Selenium is the best fit. Suppose you want to find a particular element from the current page of an e-commerce website. Let’s say the element is an image or cost of a product. Using Selenium it can be done very easily. In fact, it lets you inspect the page, get the relevant code of the element based on the element locater techniques and tests the web page without much of an effort.

Now let us try to understand what is a Robotic Process Automation and why is it of high importance.
Selenium vs RPA: What is RPA and what are its features?
- RPA was coined with the vision of empowering business users to create software bots (robots) that could interact with the system just like humans.
- It evolved from the three key predecessors: Screen scraping, workflow automation, and artificial intelligence.
- RPA bots are powerful to mimic several human actions such as log into applications, copy and paste data, move files and folders, fill in forms, scrape browsers and extract structured & semi-structured data from documents.
- It is highly dependent on Screen scraping & Workflow automation that manages workflows using drag & drop features in a visual way, which is entirely independent of coding knowledge.
- RPA is basically a combination of Artificial Intelligence and automation.
- RPA is platform independent.
To get an overview of RPA you can go through this What is RPA blog & for in-depth knowledge refer to this Robotic Process Automation guide.
Coming to the predecessors of RPA, I would say, they are just embedded into the RPA keyword. As the other tools of the RPA are licensed, we are confined to UiPath for all the demonstrations and implementation.
Screen scraping tools play a major role in data migration and integration. The first technology that created a bridge between the current system and the legacy systems. It is a component used for collecting screen display data from one application, and translating it so that another application can display it. It offers functionalities to retrieve the data by scraping the user interface of other applications.
The following features help in better understanding of RPA:
- Software bots have emerged as a potential way for organizations to achieve clear cost savings.
- For the tasks that require repetitive execution of programs, RPA would be the best option.
- It helps in the business processes like operational activities, calculations and data extraction in various organizations
- You can get a more accurate result in less time because it is easy to learn and implement.
- The number of errors is reduced.
- RPA can be used as a link to external systems that cannot be connected via other IT options.
- Security comes into action when you talk about business process automation. The data that the user will be working on will be highly protected and the risk factor reduces.
RPA is not just limited to these features. Take a look at this video to learn more about What is Robotic Process Automation (RPA) from our experts.
What is Robotic Process Automation (RPA) | Edureka
This tutorial will give you an introduction to RPA talk about the leading RPA tools such as UiPath, BluePrism and Automation Anywhere.
Selenium vs RPA: Comparison of Selenium and RPA
I will consider the following factors to compare Selenium vs RPA.
- What do these tools automate?
- Where does the automation take place?
- Are these tools open-source or paid?
- Which major component is used by Selenium and RPA?
- What is the level of automation in these tools?
- The complexity of their life cycle
- Is it platform dependent or independent?
- Knowledge of coding is required?
What do these tools automate?
Selenium automates testing of web applications.
Robotic Process Automation (RPA) automates business processes such as maintenance of records, queries, transaction processing, calculation and so on.
Where does the automation take place?
Selenium can automate only the current web page.
RPA automates all the backend processes that are time-consuming.
Are these tools open-source or paid?
- Selenium is an open-source testing tool whereas RPA tools are UiPath, Automation Anywhere, BluePrism and others.
- Among these tools, UiPath offers a platform to learn, where the community edition is free for individual use and the business edition is licensed. The other tools are for business use and are licensed.
Which major component is used by Selenium and RPA?
- Webdriver plays a very important role in automating the test cases because it overcomes all the disadvantages of Selenium RC and makes the testing process simple and clear.
- RPA makes use of bots that help in rendering possible outcome by imitating human activities.
What is the level of automation in these tools?
RPA helps in maintaining huge records of data and simplify the process and it is flexible in dealing with the clerical processes.
Selenium does not support the clerical processes taking place because it works on the front end of the web application.
The complexity of their life cycle
More simple their life cycle is, more efficient they are when it comes to the end results. Selenium has a complicated life cycle compared to RPA.
Robotic Process Automation Life Cycle
- Analysis
- Bot Development
- Testing, and
- Support & Maintenance.
Step 1: Analysis
The life cycle in RPA begins with Analysis.
- The business team works together to identify the process of RPA development.
- It helps to identify processes that are feasible for automation.
- Planning the development process with the help of resources. Then the process is formulated with an RPA lead.
- A documental approach is approved by the stakeholders after it is completed.
Step 2: Bot Development
- The bot development process takes place in a separate environment.
- Limited coding is required because it is a Wizard-driven process.
Step 3: Testing
Testing is carried out in two ways:
- RPA development testing
- Separate testing tool
Among these, RPA development testing is preferred because script correctness is verified and reviewed. Whereas, by using a separate tool, testing can be performed on a dedicated QA environment.
Step 4: Support and Maintenance
After the development and testing, it enters the Maintenance phase. Every change is updated at regular intervals. If there is an error, the process is tested and repeated continuously for a better outcome.
Selenium Life Cycle
- Test plan
- Generating basic tests
- Enhancing tests
- Running and Debugging tests
- Analyzing test results and Reporting defects
Step 1: Test Plan
- Get the application environment specifications from the development team.
- Then, identify the objects in the AUT(Application Under Test).
- Further, create the test cases.
- At last, select the appropriate framework based on the requirements.
Step 2: Generate Basic Tests
- Selenium IDE: Element locator & selenese commands.
- Selenium WebDriver: Element locator techniques & WebDriver methods are used.
Step 3: Enhancing Testing
- Insert a validation point using Assert/Verify commands.
- Synchronization with the application being tested.
- Handling expected & unexpected errors.
Step 4: Running and Debugging Tests
- Executing a test case is an important phase in the Selenium life cycle.
- Debugging is required only if there is an error in the test case.
Step 5: Analyse Results and Report Defects
- Selenium helps in giving the overview of the records and does not provide detailed reports.
- TestNG and JUnit is used to generate detailed records.
Is it platform dependent or independent?
Selenium is an open source tool which is platform independent, and can be used on any browsing platform.
In RPA, the user can use processes that can run on any of the web, desktop, and mobile applications. It is platform independent.
- If you are working with Selenium, basic knowledge of Java is required.
- RPA requires minimum coding knowledge.
Consider a scenario where you order something on any of the e-commerce websites.
- RPA helps in capturing the order details.
- Streamlines the process by simplifying the order entry.
- Integrates the details with the data entered. This reduces the discrepancies & simplifies the view of order status.
Using Selenium,
- One can create a Webdriver instance.
- Navigate to the corresponding webpage, and find a particular element on the current web page.
- Perform actions like login, sign up and so on.
- Initiate a browser response, run the tests and record the test results using a test framework.
Selenium vs RPA: Similarities between these tools.
- Both Selenium and RPA are automation tools that reduce manual intervention and enhance quality.
- Both of them follow the Rule-based process.
Now, you might ask, What if I try to use RPA as a testing tool? I would say, both Selenium and RPA help in delivering automation solutions. Talking about using it as a testing tool, it can be used to test the web application, but it is not recommended. Let me talk about the practical aspect that resists RPA from being a test machine. RPA is not directly applied to the product, but it is applied to the processes associated with the business environment. Selenium completely depends on the product for testing a case.
Selenium vs RPA: Conclusion
Talking about the factors on which they differ, I would suggest you take a look at the table:
| Parameters | Selenium | RPA |
