Python has really started to capture the imagination of developers worldwide in the past few years. It is steadily climbing the rankings and is presently third best, after Java and C, according to the Tiobe index. The easy syntax of Python code along with the vast quantity of libraries available for almost any need has made it a very firm favorite for all sorts of development. But with that broad adoption comes the need for Python to be ready for serious, commercial code quality and the best way to ensure you use one of the Python testing frameworks to both validate the logic of your coding as well as trap the more difficult logic errors which can creep in.

Python’s adaptability makes it ideal for a wide range of commercial use cases, but testing your code is crucial before publishing any Python-based products to a wider arena. This post will discuss what we mean by formal Python testing and walk you through the top six Python testing tools. By the conclusion, you’ll be able to identify the ideal testing framework for your project.

What is automated testing using Python?

Automated testing is the practice of writing programs, scripts or macros which either test programs and apps externally as if a user was clicking or touching elements of the user interface and interacting with it; or it can be a series of specially written code units and projects which instantiate the program’s objects and methods in code and test that they behave and return results as expected, usually by providing test routines which supply a set of parameters or carry out actions to exercise the code and then return true or false to indicate whether the test passed or failed.

What is a unit test?

A unit test is a specially written set of one or more programs which create or instantiate a program’s objects and calls the programs methods in a controlled way purely to test that those objects and functions behave as expected. A unit test often returns true to indicate the test was successful and when these tests are gathered together into a project it is often referred to as a “unit test project”. Many automated CD/CI (continuous integration, continuous delivery) systems will not allow new code to be integrated unless there is a test project which has all the tests it contains ‘passing’ (returning true).

A unit test is not intended to be run by an end-user and is usually written with the most minimal set of functionality required to exercise the objects, methods or functions it is designed to test. Unit tests operate at the code level rather than at the user interface level.

What is an automated test script?

An automated test script might be a program designed to run a set of unit tests or it might be a set of instructions which drive the user interface of the application to attempt to automate the testing of the various controls and input or output.

Automated test scripts are available in several different programming languages, such as Python, C#, Ruby, Java, among others. However, because Python is more closely related to the English language it helps make it easier to learn to write test scripts in Python. Furthermore, unlike other programming languages, Python is an open-source language with an accessible syntax so the mechanics of how various concepts work are more simple to read and grasp than languages like C.

What are Python testing frameworks?

A Python testing framework is a set of functions and routines which help provide the capability to perform automated testing of programs and apps. The apps might not be written in Python although the tests are.

Every Python testing framework has advantages and disadvantages, but Python’s popularity means there is almost certainly something out there that will work for your business project.

What Is PyScripter and why is it the go-to tool for Python testing frameworks?

Many developers consider PyScripter to be one of the best Python IDEs. PyScripter is an editor with syntax highlighting, a Python interpreter, a debugger, a project coordinator, and more. However, PyScripter’s inherent capability for integrated unit testing is its most noteworthy feature. As a result, it has made a name for itself as one of the greatest Python testing tools for software development.

You may carry out automated unit testing thanks to PyScripter’s automatic test creation. The unit testing GUI that comes with the PyScripter IDE is excellent. Additionally, it provides a sophisticated graphical user interface for executing unit tests, a common Python module, in its unit tests window. For further details, consult the official documentation.

The two most important toolbar buttons on this window are Refresh and Run. 

Updating the unit test panel loads the PyScripter unit tests for the active module. It’s important to note that this necessitates importing the component into the built-in interpreter. Use the tree view to select the tests you wish to run after loading a module. You may access the testing methods or class definition in the source code by double-clicking on the name of a test or test class.

Run performs the chosen tests, making it easy to use. In the tree view, the color adjacent shows the test’s state following execution. For instance, the colors green and purple indicate success. The color red indicates a Python exception. The aggregate data are immediately below the tree view, and you can learn about the errors made by clicking on the failed tests.

Is Pytest a popular Python testing framework?

Undoubtedly one of the most popular Python testing frameworks available, Pytest is an open-source testing framework. Unit testing, functional testing, and API testing are all supported by Pytest. You will want Python 3.5 or later to run it.

What are the advantages of using Pytest?

Pytest allows for small and straightforward test suites. Secondly, utilizing plugins, such as pytest-randomly, pytest-cov, pytest-django, and pytest-bdd, is very expandable. Additionally, you may include the pytest html plugin in your project to easily produce HTML reports. You may use the Pytest plugin pytest-xdist to run tests concurrently. It possesses a sizable community. Pytest is a great approach to handling context between stages and supports fixtures, which assist you in covering all the parameter combinations without rewriting test cases.

What are the disadvantages of using Pytest?

Although Pytest makes it simple to create test cases, you won’t be able to use those in any other testing framework since Pytest uses its special techniques. Therefore, compatibility is not important for Pytest.
