Which framework is best for Python automation testing

Python automation testing has always been a popular topic to get into if you want to automate your overall development and testing process. For a long time, python was the only language that had frameworks and plugins for different automated testing tasks. However, as of now, more options are available in test automation, with more languages gaining traction every day.

Most times we get different questions from our students about automation testing and the best framework to use such as; Which automation tool is best for Python? Which framework is best for Selenium with Python? Which automation tool is best?


So in this blog post, you will learn which framework you should use and why python is a diverse tool that can help you achieve your goal as a software tester or someone new to the industry.

Python has become a popular language for many different purposes. It can be used to create web applications and websites and even run full-fledged applications on your smartphone! Python's flexible syntax makes it very easy to write programs in the language. Because of this, creating Python scripts can be an easy task. But as you might already have noticed, putting together a full automated test suite with Python is quite challenging if not just impossible. This is where automation testing tools come into play. These tools allow you to perform boring repetitive tasks within no time. Automation testing tools like pytest and sublime text are some of the best Python automation testing frameworks you can find out there. However, today we will be looking at 7 excellent Python automation testing tools that can help you out when building such automated test suites.


Python is one of the most popular programming languages in the world, and it has been growing lately. The number of Python developers, both beginners and professionals, has grown significantly. This means that more complex tasks need to be performed at a higher level of automation.

What is Python Programming Language?


Python is an object-oriented programming language and one of the world's most widely used programming languages. It has many libraries, frameworks and other tools that can help you develop better applications with easy-to-understand code. Python testing automation is one such tool that you can use to ensure your code is bug-free before releasing it into production. In this article, we will look at some of the best python automation testing tools available on the market today.


Python is a popular programming language that is used to build web applications, desktop applications, commands, and more. A python is also a great option for automating your tests. It has many advantages over other languages such as Java or C++.



The benefit of Using Python as an Automation Testing tool


  • Python is a powerful programming language, and it's also a popular choice for automating tasks. Python is easy to learn and use, so it can be an ideal tool for automating repetitive tasks.


  • The benefits of using Python to automate processes include flexibility, speed and accuracy. In this article, we'll take a look at some of the best Python automation tools available today and discuss how they can help you automate your business processes.


  • Python is an elegant and powerful programming language. It's one of the most popular languages for data science, machine learning, and web development. And it's also a software development language that can be used to write automation tools and frameworks.


  • Python is not just limited to programming; it has a strong community of developers who use it in other ways as well. For example, you'll find Python scripts on GitHub to automate tasks like creating graphs and charts, processing image files, and even generating PDF reports.

Which framework is best for Python automation testing?


1. Pytest for unit testing


Pytest is an open-source software testing tool. It can test Python code and a large library of other programming languages. It can be used from the command line and runs on Linux/Unix systems as well as MacOS-X systems. Pytest offers both manual and automated testing capabilities.


It makes use of the existing test framework in your project and uses it to create new tests according to your need. You can also write your test cases or extend existing ones with new features if you have time to do so.


pytest framework for automation testing

A typical use case for Pytest is when you want to write automated tests for some parts of your application that are not covered by unit tests or even integration tests yet.

Pytest is a mature, full-featured testing framework for Python. It's used for unit testing, functional testing and regression testing. You can use it with any programming language that supports the standard library (Python 2 or 3).


Pytest has two main components: test runners and frameworks. The test runner runs tests while they're being written; it gives you access to inputs and outputs from your code as well as information about how long each test takes to run. The framework supplies various tools for writing better tests: fixtures, results collection mechanisms, etc.


2. Robot Framework


Robotic framework for automation testing

Robot Framework is a Python-based test automation framework. It's designed to be a flexible, high-level testing framework that supports keyword-driven testing. In this approach, you write your tests in terms of test cases and suites with keywords as the driving force behind what happens when those tests are run.


robotic framework

Robot Framework was created by James Edward Gray II (who also wrote Selenium) and has been around since 2006! This means it has been around long enough to have seen significant development over time—which means its features are often updated without requiring any major changes to the existing codebase(s).


3. Behave.


Behave is a BDD (Behavior Driven Development) framework for Python. It's based on Gherkin, the business readable language for specifying acceptance criteria.

Behave uses the cucumber-puppeteer library to run the tests in a headless browser, meaning you can run your automated tests without having an actual device or operating system installed on your computer. This makes it easier to test web applications that have been deployed on multiple platforms and locations because no matter which platform or location you're testing from, Behave will give you results based on what behaviour was expected along with any errors that were encountered during execution of that behaviour.


4. Lettuce

Lettuce is a Python testing tool that provides a higher-level API for writing tests. It provides a clean and simple testing API, with features such as automatic mocking, test templates and more. Lettuce is also built on the Behaviour Driven Development (BDD) framework to help develop tests easier by providing clients with common BDD assertions like @given or @when.

Lettuce supports many popular Testing Frameworks like pytest, nose and unittest2 but it can be easily integrated with any workflow you prefer through plugins like pytest-plugin-lint, pylint, tox or cProfile.


5. pyATS



PyATS testing framework

Pyatt is a python library for Automated Testing systems, which helps you automate your tests in Python. It also supports other languages like Ruby and Java.

It supports multiple frameworks such as pytest, nose, unittest2 and others.

pyATSTools support continuous integration with Travis CI toolchain via Python Package Index (PyPI) repository or custom build system integration.


6. sikuli python


sikuli python

Sikuli is a Python library for automating GUI testing. It can be used to automate any application that can be controlled by a GUI, such as web browsers and desktop applications. Sikuli is an open-source tool and it's free to use under the MIT license so you don't have to pay anything when you download it!

Sikuli works on Windows, Linux and macOS machines as well as mobile devices like Android and iOS systems. It supports almost any platform available today including Windows 2000 through Windows 10 (including Server 2016).


7. PyUnit ( Python Unit Testing Framework)


Pyunit testing framework

PyUnit is the Python unit testing framework. It’s a simple and powerful testing tool, written in Python. PyUnit provides a robust infrastructure for writing automated tests for your code, with syntax that’s easy to learn and understand.

PyUnit is a mature software testing tool. It has been under development since 2004 when it was first created by Bob Nystrom and Cameron Laird as part of their Master's thesis at Carnegie Mellon University (CMU). Since then, many people have contributed to improving its design and usability — including Ross Moore (who also wrote Cuckoo) and others who worked on CPython itself!


There are many python testing automation tools available for you to choose from. And there are a lot of factors that play into choosing which one is the best for your project.

  • The number of users: Python has become one of the most popular languages in recent years, and this should be taken into account when determining which tool will suit your needs. One thing I like about Python is that its open source and easy to modify, so if you find yourself working on something similar to what another developer already wrote but want something more specific or better suited to your particular needs (such as adding new features), then you can quickly adapt their code by yourself without having any issues with copyright laws or licensing agreements related to what they created originally (which could potentially cause problems later down the road). Another advantage here is having access.

Python is quickly emerging as the go-to automation testing language. The combination of its syntax, ecosystem, and ability to make one-off scripts makes Python an invaluable tool for automation. In this blog post, we've compiled a list of what we believe are the best Python frameworks and tools to use when automating your test cases. Each has unique strengths and weaknesses, but they all fill different niches within your automated testing process. Picking the right one depends on what you're building, how many resources you have, and how much time you can invest in learning a new library or framework.



There has been no question that the skills gap in the technology industry is a major issue. Many companies do have a process in place to handle automated testing, but there is still a glaring hole when scaling this type of testing beyond a certain point. The fact that so much time and effort is spent on solving different aspects of automation testing is what makes it so compelling. Ultimately, automated testing will become an even more relevant topic in the years to come.
