Taschenbuch. Zustand: Neu. Neuware - Test applications, packages, and libraries large and small with pytest, Python's most powerful testing framework. pytest helps you write tests quickly and keep them readable and maintainable. In this fully revised edition, explore pytest's superpowers - simple asserts, fixtures, parametrizati…on, markers, and plugins - while creating simple tests and test suites against a small database application. Using a robust yet simple fixture model, it's just as easy to write small tests with pytest as it is to scale up to complex functional testing. This book shows you how.pytest is undeniably the best choice for testing Python projects. It's a full-featured, flexible, and extensible testing framework. pytest's fixture model allows you to share test data and setup procedures across multiple layers of tests. The pytest framework gives you powerful features such as assert rewriting, parametrization, markers, plugins, parallel test execution, and clear test failure reporting - with no boilerplate code.With simple step-by-step instructions and sample code, this book gets you up to speed quickly on this easy-to-learn yet powerful tool. Write short, maintainable tests that elegantly express what you're testing. Speed up test times by distributing tests across multiple processors and running tests in parallel. Use Python's builtin assert statements instead of awkward assert helper functions to make your tests more readable. Move setup code out of tests and into fixtures to separate setup failures from test failures. Test error conditions and corner cases with expected exception testing, and use one test to run many test cases with parameterized testing. Extend pytest with plugins, connect it to continuous integration systems, and use it in tandem with tox, mock, coverage, and even existing unittest tests.Write simple, maintainable tests quickly with pytest.What You Need:The examples in this book were written using Python 3.10 and pytest 7. pytest 7 supports Python 3.5 and above.

Taschenbuch. Zustand: Neu. Neuware - The office isn't as essential as it used to be. Flexible working hours and distributed teams are replacing decades of on-site, open-plan office culture. Wherever you work from nowadays, your colleagues are likely to be somewhere else. No more whiteboards. No more water coolers. And certainly…no Ping-Pong. So how can you organize yourself, ship software, communicate, and be impactful as part of a globally distributed workforce We'll show you how. It's time to adopt a brand new mindset. Remote working is here to stay. Come and join us.Remote working is on the rise. Whether or not we are remote workers, it is likely we are all part of a global workforce. We need to learn to interact remotely, because we are all remote from someone in some way. Rather than simply simulating the way we'd usually work together via digital means, we have to learn new communication skills and adopt a different mindset in order to work remotely effectively, efficiently, and, most importantly, healthily.We'll start by getting you set up with the right equipment and habits. Then, we'll learn the mindset of treating everyone as remote, and conquer both synchronous and asynchronous communication. You'll learn how to produce amazing artifacts, how to communicate clearly, and how to manage yourself and your teams. Then we'll look at the bigger picture: from measuring the remote readiness of your workplace, to creating a handbook for your team, to exploring remote-first culture and tackling burnout and mental well-being.Fundamentally we'll see that adopting a remote-working mindset can do wonders for our organization, our effectiveness, and our impact in our careers. It can even create a more diverse and inclusive industry for us all to work in.So what are you waiting for The remote future is now. Be a part of it.What You Need:There are no prerequisites to reading this book, other than having had some experience of working in the software industry and a healthy curiosity.
