Testing and Running Python Web Applications

Developing a web application is only half the battle; ensuring it runs correctly, securely, and reliably is what separates amateur code from production-ready software. This text-based course guides you through the essential process of launching, testing, and debugging Python web applications, giving you the confidence to deploy bug-free code. You will learn how to: Understand the core concepts of local web servers, ports, and secure HTTPS connections; Practice manual verification and handle common local environment issues like SSL certificate warnings; Learn the fundamentals of writing automated tests using the modern pytest framework; Build integration tests to verify web routes, HTTP requests, and application responses; Configure mock objects to isolate your tests from external databases and third-party APIs. You will start with foundational web concepts and manual testing before advancing to writing robust, automated test suites that fit seamlessly into your development workflow. This course is designed for beginner Python developers who want to transition from writing basic scripts to building and testing reliable web applications, with no prior testing experience required.
