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.
