This article focuses on "what Python frameworks are commonly used in automated testing", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn what Python frameworks are commonly used in automated testing.

Commonly used frameworks are Robot Framework, Pytest, UnitTest/PyUnit, Behave, and Lettuce. Pytest, Robot Framework and UnitTest are mainly used for functional and unit testing, while Lettuce and Behave are only used for behavior-driven testing.

1. Robot Framework

One of the Python testing frameworks, Robot Framework is used in test-driven (test-driven) type development and acceptance. Although developed by Python, it can also run on .net-based IronPython and Java-based Jython. As a Python framework, Robot is also compatible with platforms such as Windows, MacOS, and Linux.

Before you can use Robot Framework (RF), you need to install Python 2.7.14 or above. Python 3.6.4 is recommended to ensure that appropriate comments can be added to the code snippet and that changes to the program can be tracked. You also need to install the Python package manager, pip.

II. Pytest

Pytest, which is suitable for many kinds of software testing, is another automated testing framework of Python type. With its open source and easy-to-learn characteristics, the tool is often used by QA (quality Analysis) teams, development teams, individual teams, and various open source projects. Given that Pytest has practical functions such as "assert rewriting", many large Internet applications, such as Dropbox and Mozilla, have switched from unittest (Pyunit) to Pytest.

In addition to basic Python knowledge, users do not need more technical reserves. In addition, users only need to have a test device with a command-line interface and install the Python package manager and IDE tools that can be used for development.

III. UnitTest/PyUnit

UnitTest/PyUnit is a standardized Python class automated testing framework for unit testing. The base class TestCase provides various assertion methods, as well as all cleanup and setup routines. Therefore, each method in the Testcase subclass is prefixed with the noun "test" to identify that they can be run as test cases. Users can use the load method and the TestSuite class to group and load various tests.

You can use it together to build a custom test runner. Just as we use Junit to test Selenium, UnitTest uses UnitTest-sml-reporting and can generate reports of various XML types. Because UnitTest uses Python by default, we don't need any prerequisites. In addition to having a basic knowledge of the Python framework, you can also install pip and IDE tools for development.

IV. Behave

Behavior-driven development is a method based on agile software development. It encourages collaboration among developers, business participants, and QA personnel. The Python testing framework Behave allows teams to avoid complex situations and perform BDD tests. In essence, this framework is similar to SpecFlow and Cucumber and is often used to perform automated tests. Users can write test cases in a simple and easy-to-read language and paste them into the code during their execution. Moreover, those established behavior norms and steps can also be reused in other test scenarios.

Anyone with basic knowledge of Python can use Behave. Other prerequisites include: install Python 2.7.14 or above first. Collaborate with Behave through the Python package manager or pip. Most developers will choose Pycharm as their development environment, but you can also choose other IDE tools.

5. Lettuce

Lettuce is another behavior-driven class automation tool based on Cucumber and Python. Lettuce focuses on common tasks with the characteristics of behavior-driven development. It is not only easy to use, but also makes the whole testing process smoother and even more interesting. Install Python 2.7.14 with IDE and above. Of course, you can also use Pycharm or any other IDE tool. At the same time, you need to install the Python package manager.

The Python framework of automated testing, Pytest, Robot Framework and UnitTest can be used mainly for functional and unit testing, while Lettuce and Behave are only suitable for behavior-driven testing. For functional testing, Pytest is. If you are new to Python-based automated testing, Robot Framework is the starter tool. Although its function is limited, it is very easy to use. For Python-based BDD testing, Lettuce and Behave are equally excellent.

At this point, I believe you have a deeper understanding of "what Python frameworks are commonly used in automated testing". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
