This package enables dynamic orchestration of Celery environments for testing tasks in isolated conditions, leveraging Docker & pytest-docker-tools for environment simulation.

This project will create an empty file of a type requested. If possible, that file will be the smallest valid file for that type. For example, an empty jpg will be a 1x1 pixel jpg.

This package provides a Pytest plugin powered by VCR.py to record and replay HTTP traffic.

icontract brings design-by-contract to Python with informative violation messages and inheritance. icontract provides two function, require and ensure for preconditions and postconditions respectively. Additionally, it provides a class decorator, invariant, to establish class invariants.

This plugin makes it simple to test general data, images, files, and numeric tables by saving expected data in a data directory (courtesy of pytest-datadir) that can be used to verify that future runs produce the same data.

Testfixtures is a collection of helpers and mock objects that are useful when writing automated tests in Python.

nox is a command-line tool that automates testing in multiple Python environments, similar to tox. Unlike tox, Nox uses a standard Python file for configuration.

This package contains hypothesis strategies for generating Python programs, something like CSmith, a random generator of C programs.

Data-Driven Tests (DDT) allow you to multiply one test case by running it with different test data, and make it appear as multiple test cases.

Cram is a functional testing framework for command line applications. Cram tests look like snippets of interactive shell sessions. Cram runs each command and compares the command output in the test with the command’s actual output.

This package provides line_profiler - a Python module for doing line-by-line profiling of functions. kernprof is a convenient script for running either line_profiler or the Python standard library's cProfile or profile modules, depending on what is available. It's a successor of https://github.com/rkern/line_profiler.

This package provides a pytest plugin for efficiently checking PEP8 compliance.

Ruff aims to be orders of magnitude faster than alternative tools while integrating more functionality behind a single, common interface. Ruff can be used to replace Flake8 (plus dozens of plugins), Black, isort, pydocstyle, pyupgrade, autoflake, and more, all while executing tens or hundreds of times faster than any individual tool.

This pytest plugin provides fixtures to simplify Flask app testing.

This package provides a pytest plugin that allows multiple failures per test.

The python-mypy-extensions module defines experimental extensions to the standard typing module that are supported by the MyPy typechecker.

crosshair is an analysis tool for Python that works by repeatedly calling your functions with symbolic inputs. It uses an SMT solver explore viable execution paths and find counterexamples for you.

Blockbuster is a Python package designed to detect and prevent blocking calls within an asynchronous event loop. It is particularly useful when executing tests to ensure that your asynchronous code does not inadvertently call blocking operations, which can lead to performance bottlenecks and unpredictable behavior.

It does this by wrapping common blocking functions and raising an exception when they are called within an asynchronous context. Note that Blockbuster currently only detects asyncio event loops and is tested only with CPython.

This is a py.test plugin to facilitate the generation and comparison of data arrays produced during tests, in particular in cases where the arrays are too large to conveniently hard-code them in the tests.

This package is a pytest plugin for managing VCR.py cassettes.

This package implements a spell checker for source code that does not try to be particularly smart and instead does the simplest thing that can possibly work.

This package provides a plugin for the pytest framework that allows developers to detect whether any file handles or other file-like objects were inadvertently left open at the end of a unit test.

This package provides a plugin for Pytest which adds the ability to retry flaky tests, thereby improving the consistency of the test suite results.

This is a Python library for test combinations generator. The generator allows one to create a set of tests using pairwise combinations method, reducing a number of combinations of variables into a lesser set that covers most situations.
