To choose language in Selenium web driver during an Automation testing, BugRaptor’s always uses the Java language over Python, as it is more powerful language and Selenium is also developed by java.

Why We Choose Java Over The Python In Selenium Web Driver?
1. Why We Choose Java Over The
Python In Selenium Web Driver?
2. Introduction
Automation testing is the process of writing code which tests the
application automatically without requiring any human intervention
and produced results can be analyzed for further testing or
reporting purpose which further reduces testing efforts and helpful
in delivering quality software faster and more affordably. It initially
requires cost to develop automation test suite but helps in
delivering better quality software with less effort over a period of
time as less manpower will be required to perform repetitive tasks.
Although numerous organizations are using automation testing to a
great extent, yet still enormously depend on manual testing. This is
due to lack of knowledge of benefits of automation testing in the
software development process. There is a set of pre-defined test
cases which is executed deliberately manually. The outcome of
each test case is then compared with the expected behavior and
reporting the results or discrepancies if found.
3. Repetitive testing or repeating a set of test case execution is very
usual in continuous delivery development models and thus
software is prone to errors in such environment. Testing can
become a tedious task when it comes to cross platform or cross
browser testing. Performing one thing over and over again for
different operating systems not only consumes a lot of time but also
shifts the focus from the actual functionality to be delivered;
especially when deadlines are tight. Hence, it is crucial that
automation testing should be done in almost every organization to
save time and to deliver quality software.
There are many tools available in market for this purpose but
“Selenium” stands out of all these when it comes to web
automation testing. Now, when we have such a powerful tool which
is open source and large community support spanning many
operating systems, browsers and languages; then question arises:
Which language it should be used with? As already mentioned,
selenium is compatible with numerous languages namely; Perl,
Ruby, C#, Java, python and so on. In the rest of the article, let’s
have a look at why using “Java” with Selenium web driver is at
more advantageous over “Python” with the same for your
4. Python vs Java
What is Python?
Python is a high-level language which is interpreted and simple to
understand. It is a open source language known for its flexibility
and extensive libraries.
Why Selenium with Python:
It is easy for coding and also easily readable
Runs faster while comparing other programming
Also Provides Dynamic Typing Nature
Embeddable which gives python scripting capabilities
5. Selenium with Java
Java is the most widely used and oldest programming language
due to its robust nature. It is platform independent which mean
program written for windows will also run for other types of
operating system. It has a very large supporting community which
secures its position on the top in the future as well.
Why Selenium with Java?
Stronger community options
Selenium is also developed by Java
Large number of users for Selenium with Java
More than 80% of experts prefer to work Selenium with Java
Learning Java and its set of libraries will help you in many ways
Programs written in java are faster than python
6. Pros and cons
The phrase “dynamically typed” means that Python performs
type checking at runtime, while statically typed languages like
Java perform type checking at compile time. Python can
compile even if program contains errors due to its dynamic
nature and would result in the unsuccessful execution of the
script. On the flip side, Java has JIT compiler, which shows
errors at compile time only saving the user’s extra effort of
recognizing errors at an early stage of development.
Debugging: Java is statically typed which data types of
variables should be declared before using them, while Python
does not. Python is more flexible and can save you time and
space when running scripts. However, it can cause issues at
runtime.
Performance: Choosing a language narrows down to what we
are trying to achieve with the code. Performance is not always
the parameter, but it is always a basic metric to decide the
capability of any technology. Code optimization and virtual
machine execution makes Java more efficient when it comes to
7. Changing Old Systems: Python is more effective than java
when it comes to adapting legacy systems. Existing system
can be changed easily using python language due to its
embeddable capabilities. Hence, one need not to fully rewrite
and revamp the system like it needs to be done for Java.
As far as choosing one language is concerned, both have
their pros and cons. Automation with java is more predictable
and reliable due to language’s static type system, which
makes automated refactored.
On the other hand, Python’s dynamic system relies on
brevity, fluidity, and experimentation in code, giving it more
versatility than Java’s rigid style. Python has also been
adapting to automated testing in modern development, but
this happens more frequently in integration instead of unit
testing.
8. JVM code can be JIT-compiled efficiently, using a fast
compiler. But the same would be hard for Python, because
of its dynamically typed nature. JVM translates to a fairly
low level and straightforward native code, but for the
dynamic languages you’d have to generate dynamic
dispatch for literally all the basic operations and for all the
method calls. This dynamic dispatch is the primary
hindrance for python to be faster than java.
9. Conclusion
To sum up, it is obvious from the above arguments that using
Selenium with Java is preferred by more than 80% of
professionals but it also doesn’t mean that learning Selenium
with Python is not useful. Selecting the programming languages
depends on where you going to use.
We, at BugRaptor’s, have developed our own automation
framework using java language and delivered many automation
projects using the same language which has satisfied
numerous clients’ requirements and produced high quality
software.
