Learn Pytest in 60 Minutes : Python Unit Testing Framework

py.test is an alternative, more Pythonic way of writing your tests. The pytest framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries. pytest is a mature full-featured Python testing tool that helps you write better programs. Learn Pytest basic functionality | Setup & Tear Down | Fixtures Beginning with a brief introduction and setup of Pytest. We will see How to install pytest, Using Options with Pytest, Parameterizing tests (pytest.mark.parametrize), pytest fixtures + setup/teardown methods, Using PyCharm to run pytest tests. The best part is, the overhead for creating unit tests is close to zero! How to use Options with pytest: How to run cases? • pytest tests/test_mod.py • pytest tests/ • pytest -k match # def test_match(): -k EXPRESSION only run tests which match the given substring expression. • pytest --showlocals # trace context • pytest -x # stop on first failure case • pytest --maxfail=2 # on the second • pytest -s # enable `print` output • pytest --durations=5 # list top 5 slowest cases • pytest --tb=long # default traceback • pytest --tb=line # oneline • pytest --tb=short • pytest --tb=native # Python default traceback -m MARKEXPR only run tests matching given mark expression. example: -m 'mark1 and not mark2'. --markers show markers (builtin, plugin and per-project ones). -x, --exitfirst exit instantly on first error or failed test. --maxfail=num exit after first num failures or errors. What is Unit Testing - According to wikipedia, unit testing is a software testing method by which individual units of source code are tested to determine whether they are fit for use. Why Unit Test? - Tests Reduce Bugs in New Features and Existing Features Tests Are Good Documentation Tests Reduce the Cost of Change Faster Debugging Faster Development Better Design Python Testing frameworks unittest - In the Python Standard Library nose - Not in the Standard Library. Simpler tests than unittest pytest - Not in the Python Standard Library. run with following command: pytest test_math_func.py -v or py.test #PythonTutorialforBeginners #ProgrammingKnowledge #PyTest #PythonCourse. ★★★Top Online Courses From ProgrammingKnowledge ★★★ Python Programming Course ➡️ http://bit.ly/2vsuMaS ⚫️ http://bit.ly/2GOaeQB Java Programming Course ➡️ http://bit.ly/2GEfQMf ⚫️ http://bit.ly/2Vvjy4a Bash Shell Scripting Course ➡️ http://bit.ly/2DBVF0C ⚫️ http://bit.ly/2UM06vF Linux Command Line Tutorials ➡️ http://bit.ly/2IXuil0 ⚫️ http://bit.ly/2IXukt8 C Programming Course ➡️ http://bit.ly/2GQCiD1 ⚫️ http://bit.ly/2ZGN6ej C++ Programming Course ➡️ http://bit.ly/2V4oEVJ ⚫️ http://bit.ly/2XMvqMs PHP Programming Course ➡️ http://bit.ly/2XP71WH ⚫️ http://bit.ly/2vs3od6 Android Development Course ➡️ http://bit.ly/2UHih5H ⚫️ http://bit.ly/2IMhVci C# Programming Course ➡️ http://bit.ly/2Vr7HEl ⚫️ http://bit.ly/2W6RXTU JavaFx Programming Course ➡️ http://bit.ly/2XMvZWA ⚫️ http://bit.ly/2V2CoAi NodeJs Programming Course ➡️ http://bit.ly/2GPg7gA ⚫️ http://bit.ly/2GQYTQ2 Jenkins Course For Developers and DevOps ➡️ http://bit.ly/2Wd4l4W ⚫️ http://bit.ly/2J1B1ug Scala Programming Tutorial Course ➡️ http://bit.ly/2PysyA4 ⚫️ http://bit.ly/2PCaVj2 Bootstrap Responsive Web Design Tutorial ➡️ http://bit.ly/2DFQ2yC ⚫️ http://bit.ly/2VoJWwH MongoDB Tutorial Course ➡️ http://bit.ly/2LaCJfP ⚫️ http://bit.ly/2WaI7Ap QT C++ GUI Tutorial For Beginners ➡️ http://bit.ly/2vwqHSZ ★★★ Online Courses to learn ★★★ Get 2 FREE Months of Unlimited Classes from skillshare - https://skillshare.eqcm.net/r1KEj Data Science - http://bit.ly/2lD9h5L | http://bit.ly/2lI8wIl Machine Learning - http://bit.ly/2WGGQpb | http://bit.ly/2GghLXX Artificial Intelligence - http://bit.ly/2lYqaYx | http://bit.ly/2NmaPya MERN Stack E-Degree Program - http://bit.ly/2kx2NFe | http://bit.ly/2lWj4no DevOps E-degree - http://bit.ly/2k1PwUQ | http://bit.ly/2k8Ypfy Data Analytics with R - http://bit.ly/2lBKqz8 | http://bit.ly/2lAjos3 AWS Certification Training - http://bit.ly/2kmLtTu | http://bit.ly/2lAkQL1 Projects in Java - http://bit.ly/2kzn25d | http://bit.ly/2lBMffs Machine Learning With TensorFlow - http://bit.ly/2m1z3AF | http://bit.ly/2lBMhnA Angular 8 - Complete Essential Guide - http://bit.ly/2lYvYRP Kotlin Android Development Masterclass - http://bit.ly/2GcblsI Learn iOS Programming Building Advance Projects - http://bit.ly/2kyX7ue ★★★ Follow ★★★ My Website - http://www.codebind.com DISCLAIMER: This video and description contains affiliate links, which means that if you click on one of the product links, I’ll receive a small commission.
