Pytest is a Python testing framework that originated from the PyPy project. It can be used to write various types of software tests, including unit tests, integration tests, end-to-end tests, and functional tests. Its features include parametrized testing, fixtures, and assert re-writing.
Unit testing, a.k.a. component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior. [1] Unit testing describes tests that are run at the unit-level to contrast testing at the integration or system level.
This can be modified by options to the doctest runner. In addition, doctest has been integrated with the Python unit test module allowing doctests to be run as standard unittest testcases. Unittest testcase runners allow more options when running tests such as the reporting of test statistics such as tests passed, and failed.
Unit testing framework with automatic test registration. Supports theories and parameterized tests. Each test is run in its own process, so signals and crashes can be reported. Can output to multiple formats, like the TAP format or JUnit XML. Supports Linux, macOS, FreeBSD, Windows. CU [50] 3-clause BSD
Wing Pro supports unit testing by allowing running and debugging of unit tests written for the unittest, pytest, doctest, nose, and Django testing frameworks. It optionally tracks code coverage, to indicate how well code is being tested and to re-run only tests affected by changes to code.
[1] [2] Its use began to become popular in the Python community from around 2015. [3] tox acts a wrapper for both virtual environments and test automation tools, to simplify the consistent testing of Python code across a range of environments. [4] It integrates the use of a virtualisation tool, such as virtualenv, with a test script such as ...
According to Google's testing blog, unit tests should make up the majority of your testing strategy, with fewer integration tests and only a small amount of end-to-end tests. [19] Unit tests: These are tests that test individual components or units of code in isolation. They are fast, reliable, and isolate failures to small units of code.
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
