A programming language is a language designed to produce desired machine code output. It allows us to give instructions to computers 👩💻 Developers use programming languages to create programs, apps, websites, and more. There are many different programming languages, and before deciding which one you should learn, you will need to determine what you intend to use it for.
Python is a good programming language for beginners and is therefore often used to teach the principles of programming. Additionally, because this language is often used as a training tool for coding, it is open-source, which makes it very accessible.
Python is also object-oriented, which means that you can reuse blocks of coding, a feature that further simplifies work for beginning coders. Python 3.9.0, the most recent major release, introduced some additional features that can streamline programming.
It’s worth mentioning that over the years, Python has been gaining momentum among both testers and developers, and it is the fastest-growing programming language out there (as we can see in the Stack Overflow Trends chart below):
There are quite a few reasons as to why Python’s popularity has been rising in the test automation field, and why it’s thought of as one of the best choices for learning code. I recommend reading more about it in this Top 8 Python Testing Frameworks in 2021.

|Useful for complex applications, such as those that have a central role in an organization’s processes||Useful for simple data management applications|
|Generally allows for customization with options to use code or scripting||Easy management of apps that are updated frequently|
|Customization options may be non-existent or difficult to use without some programming knowledge|
While there are many misconceptions about codeless automation testing, it has a number of benefits 💡 No-code development programs allow people to develop application software without needing to know how to code. This is accomplished through the use of a graphical user interface (GUI) that allows them to mix and match existing templates and other pre-made components.
There are many different options for no-code software, and the user’s capabilities within the software will depend on the features available through that particular program.
No one programming language stands head-and-shoulders above the rest in terms of its suitability for test automation. This is because what will work best for your software testing will depend on many factors, such as what language the target software is being developed in.
It’s worth mentioning that Java and Python are generally easier languages to learn — this is worth keeping in mind when exploring test automation as a beginner.
That being said, there are a few hallmarks of a programming language that is well-suited to test automation 📌 Ideally, a programming language used for test automation should be:
- Portable: You don’t want to have to adjust the programming for different platforms. It will also always be helpful to conduct cross-platform testing to further ensure the portability of the code.
- Flexible: You will want to be able to tweak the programming as needed.
- Widely known and used: If a programming language is widely known and used, it will be easier to find people with experience in it, and you can benefit from community knowledge about the language.
- Easy to use: It will be helpful to choose a relatively easy-to-use programming language, as the coding for test automation is not typically very complex, and an easier language will make training related to test automation a simpler task if you can find someone with sufficient existing experience.
When developing code for testing, it can help to use an open-source automation framework, such as TestProject OpenSDK, to get started. With that in mind, the following programming languages are widely thought to be particularly well-suited to test automation:
