Although often overlooked, testing is an essential step in the Software Development Life Cycle (SDLC). Python comes with its built-in testing framework called unittest. However, some developers find writing tests in unittest to be complicated. In recent years, pytest, a third-party testing framework, has gained popularity among developers for its ease of use and flexibility.
Pytest is a Python testing framework designed to assist developers with writing better systems and releasing them with confidence. It requires less boilerplate code, making test suites more readable and easy to maintain. A simple assert statement is used, rather than the assertSomething methods of unittest, making it easier to write and understand tests.
Advantages:
Supports compact test suite.
No need for the debugger or any explicit test log.
Multiple fixtures
Extensible plugins
Easy and simple test creation.
Possible to create test cases with fewer bugs.
Limitations:
Not compatible with other frameworks.
