Edit details

unittest features and specs

Standard Library Integration
Unittest is part of the Python Standard Library, which means it is included with every standard Python installation. This makes it easily accessible and eliminates the need for additional dependencies.
Discoverability
Unittest automatically discovers tests, which makes it simpler to organize and run a large suite of tests.
Test Suite Management
It provides powerful mechanisms for structuring test cases, including test suites, test cases inheritance, and grouping of tests, allowing for better organization.
Compatibility with Other Testing Frameworks
Unittest is compatible with test runners from other testing frameworks like pytest, providing flexibility and integration with more advanced features if needed.
Setup and Teardown Facilities
It provides built-in setup and teardown methods with setUp(), tearDown(), setUpClass(), and tearDownClass(), which help in preparing the environment before tests and cleaning up afterward.

Possible disadvantages of unittest

Verbose Syntax
The syntax for writing tests in unittest can be more verbose compared to some other testing frameworks, like pytest, which may lead to more boilerplate code.
Less Expressive Assertions
Unittest comes with a set of built-in assertions that are sometimes not as expressive or convenient as those provided by other testing libraries like pytest.
Limited Fixtures Flexibility
While unittest provides basic setUp and tearDown methods, it lacks more sophisticated fixtures that other frameworks like pytest offer, which can lead to less flexible test setups.
Steeper Learning Curve
For beginners, unittest can have a steeper learning curve compared to simpler or more modern testing frameworks, mainly due to its structure and the amount of boilerplate.

The last part of our CI/CD was running tests and getting coverage reports. In the Python ecosystem, pytest is an extremely popular testing framework. Though very tempting and might still be used later on, we will stick with Python's built-in testing library, unittest, and use coverage for measuring code test coverage of our program. Let's start with the test setup:. - Source: dev.to / 4 months ago

How to improve third-party libraries with Kotlin extensions
The extensions are not particularly useful in this scenario because the described functionality can be incorporated into the Host class. On the other hand, they flourish in test frameworks like Kotest and enable the rapid development of useful add-ons like custom matchers. Extending third-party libraries with utility functions is another prevalent use case. In the next sections, we'll zero in on this specific aspect. - Source: dev.to / over 2 years ago
