Selenium  FrameWork:

The Selenium framework is a set of automated testing tools built on the JavaScript framework. It could run the tests on the target browser, drive the interactions on the needed web page, and rerun them without requiring any operator intervention.

Manual testing, which takes a lot of time and effort, is no longer necessary. Selenium is in line with Agile and DevOps, both of which promote a continuous delivery approach. As a result, Selenium has become one of the most popular testing tools since it satisfies the need for rapid and reliable testing, allowing businesses to save time and money on testing.

PyTest Framework

PyTest is a testing framework that lets users create test programs in Python. It helps in the creation of easy and scalable test cases for databases, APIs, and user interfaces. PyTest is mostly used for developing API tests. It assists with the creation of tests ranging from simple unit tests to sophisticated functional tests.

ADVANTAGES OF PyTest:

1. Because of its basic and simple syntax, it's a comfort to get started with.

2. Tests can be run in parallel.

3. Can perform a single test or a group of tests.

4. Tests are detected automatically.

5. Tests can be skipped.

6. Open-source software.

Robot Framework

Robot Framework is a free and open-source framework for acceptance testing and test-driven development. For writing test cases, it uses three separate test case styles: keyword-driven, behavior-driven, and data-driven. This characteristic makes it quite simple to comprehend. In a tabular structure, test cases are written in keyword language. External libraries and open source technologies that may be utilized for automation are well supported by the Robot Framework. Selenium Library, which is used for web development and UI testing, is the most common library used with Robot Framework.

Behave Framework:

Simply said, behavior testing entails determining how an application acts in specific scenarios. Our consumers frequently provide us with the behavior. They describe an application's functionality, and we build code to satisfy its requirements. Behavioral tests are a technique for putting their criteria in writing. This naturally leads to behavior-based growth (BDD).

PyUnit (or UnitTest) Framework

The Python unit testing framework, sometimes known as "PyUnit," was created by Kent Beck and Erich Gamma as a Python language version of JUnit. Since Python 2.1, PyUnit has been included in the Python Standard Library.

Test automation, sharing of setup and shutdown code for tests, aggregation of tests into collections, and test independence from the reporting system are all supported by the Python unit testing framework. The unittest module includes classes that make supporting these criteria for a collection of tests simple.

Nose2 Framework

The successor to the nose is nose2. It's a plugin-based unit test. Because nose2 is a new project, it does not support all of the nose's features. For a complete list, see differences. The goal of nose2 is to expand unit tests in order to make testing more pleasant and understandable.

Testify Framework

The Java implementation of the Semantic Testing standard is called Testify. Testify offers users a standard set of primitives that can be learned once and used to build test cases anywhere. Testify provides primitives and extension points for developers to make their libraries and frameworks testable.

Lettuce Framework

Lettuce is a Behavior Driver Development framework for automating Python tests based on plain-text descriptions. This enables you to create tests that even your company's executives can comprehend. You may also utilize CrossBrowserTesting's cloud testing infrastructure to run your tests with Lettuce.
