Learn the pytest way to write simple tests which can also be used to write complex testsKey FeaturesBecome proficient with pytest from day one by solving real-world testing problemsUse pytest to write tests more efficientlyScale from simple to complex and functional testingBook DescriptionPython's standard unittest module is based on the xUnit family of frameworks, which has its origins in Smalltalk and Java, and tends to be verbose to use and not easily extensible.The pytest framework on the other hand is very simple to get started, but powerful enough to cover complex testing integration scenarios, being considered by many the true Pythonic approach to testing in Python.In this book, you will learn how to get started right away and get the most out of pytest in your daily workflow, exploring powerful mechanisms and plugins to facilitate many common testing tasks. You will also see how to use pytest in existing unittest-based test suites and will learn some tricks to make the jump to a pytest-style test suite quickly and easily.What you will learnWrite and run simple and complex testsOrganize tests in fles and directoriesFind out how to be more productive on the command lineMarkers and how to skip, xfail and parametrize testsExplore fxtures and techniques to use them effectively, such as tmpdir, pytestconfg, and monkeypatchConvert unittest suites to pytest using little-known techniquesUse third-party pluginsWho this book is forThis book is for Python programmers that want to learn more about testing. This book is also for QA testers, and those who already benefit from programming with tests daily but want to improve their existing testing tools.
