Behave

Behave is widely regarded as one of the top Python frameworks for testing, especially beneficial for implementing Behavior-Driven Development (BDD) practices. This Agile development approach facilitates collaboration among developers, stakeholders, and quality analysts. By leveraging Behave, the seamless execution of BDD processes is facilitated without encountering significant challenges. Notably, Behave shares many similarities with Cucumber.

Behave allows for the creation of test scripts in a straightforward language that can then be integrated into the existing codebase. This framework facilitates the reusability of predefined steps across multiple use-case scenarios. To begin working with Behave, you must install Python 2.7.14, pip, and configure PyCharm accordingly.

A few pivotal features of the Behave are:

• It uses a domain vocabulary and semi-formal language to describe system behavior. This guarantees that everyone on the team utilizes consistent terminology to describe the system’s behavior.
• Provide a set of building blocks to execute various test cases. This way, developers can work on numerous modules and coordinate team endeavors effectively.
• All the test specifications are written using a similar format. Regardless of the specifications or the specific modules being tested, ensuring that all specifications adhere to a consistent structure and format is essential. This practice is vital for enhancing clarity in communication between developers and quality assurance personnel.
• Uses semi-formal language to define system behavior. With this feature, developers can communicate with each other and better understand what is being developed.

Pytest

Pytest is a widely adopted Python framework that is open source and facilitates unit testing, functional testing, and API testing. It offers ease of use and learning, making it suitable for both individual practice and open-source projects. Its simple and intuitive syntax enables straightforward creation and execution of automation tests.

A few pivotal features of the Pytest are:
