Choosing Between Java and Python for Selenium Automation

Selenium automates browsers. It is a tool, or basically a suite (many other tools can be installed inside Selenium tools like TestNG, Maven, etc.). Selenium is a parent tool for a range of tools and libraries that helps automate testing in many browsers. Selenium allows us to automate in multiple languages, such as Java, Python, CSharp, Ruby, JavaScript, Kotlin, etc.

Before making a decision, consider the following crucial factors:

Career Change to Development, AI, or Devops Role: Because Python may be used for artificial intelligence, machine learning, and data science, it will be easier for those with Python experience to transition to greater work prospects. Python developers earn significantly more than Java developers due to increased demand in fields such as machine learning, data analytics, and cyber security. This is also determined by a variety of circumstances, including geography, abilities, experience, and organisation.

Job opportunities:

Java has more jobs than Python with Selenium. Don’t believe you can find the same information on LinkedIn.

Platform independent:

Because they use their own virtual machines (PVM and JVM, respectively), both can be run on MAC, Windows, and Linux platforms. 

Python is a language that can be interpreted, which means that a program’s source code must be transformed into bytecode before being run by the Python virtual machine. This additional step causes Python programmes to run slower than Java programmes.


Python has a simpler syntax than Java. The Python programming language syntax shares many similarities with Perl, C, and Java programming languages. Python is reasonably simple to learn since its readability and other structural components are intended to be understandable, particularly for English speaking.

Popularity / support:

 Despite the fact that GitHub has more code available for Python than Java, and despite Python being born before Java, Java is still the most famous programming language since there are more jobs available for Java than Python, and Java is a better established language than Python.

Selenium performs faster when Java is utilised. Java runs quicker than Python since it is a compiled language. Python is an interpreted language that decides data type at runtime, making execution slower and less efficient than Java.


According to the records, almost 80% of software testers use Selenium with Java. But this is not an indication that learning Selenium with Python is a waste of time. The programming options, such as Java Selenium or Python Selenium framework, must be chosen based on their intended use. 

As a result, it is impossible to say whether Selenium works better with Java or Python due to several advantages and disadvantages at both ends.

In conclusion, both Java and Python have their unique advantages when it comes to working with Selenium for automation testing. While Java’s strong typing and extensive libraries make it a popular choice for many professionals, Python’s simplicity and readability have also made it a favourite among developers. Ultimately, the decision of which language to use with Selenium will depend on the specific requirements of the project, as well as the preferences and expertise of the automation testers. Regardless of the language chosen, mastering automation testing with Selenium will undoubtedly open up exciting career opportunities in the software testing industry. Whether you choose to pursue automation testing with Java or Python, continuous learning and skill development will be key in achieving success in this field. If you are looking to start a career in automation testing with python  consider enrolling in a Software Automation Testing course to gain the necessary skills and knowledge to excel in this industry.
