Odoo 15 Development Essentials - Fifth Edition

Overview of this book

Odoo is fast becoming the reference open source platform for business applications thanks to the fact that it provides the infrastructure needed for developers to deliver software solutions for any business process quickly. Odoo's layered module approach makes it particularly effective for combining and extending features. This updated fifth edition is a tutorial-style introduction to essential Odoo development topics. The book starts by covering the development essentials for building business applications and takes you through Odoo installation and configuration, gradually transitioning from having no specific knowledge of Odoo to being ready for application development. You'll then learn how to develop your first Odoo application, while covering topics such as models and views. Later chapters will get you up to speed with using server APIs to add business logic, helping you lay a solid foundation for advanced topics. As you progress, you’ll get equipped to build and customize your applications and explore the new features available in Odoo 12 and beyond, such as in-memory ORM and computed writable fields. Finally, you’ll gain insights into building business logic and using the Odoo API to integrate with various applications. By the end of this book, you’ll be able to build business apps from scratch using the latest version of Odoo.

Step 3 – Adding automated tests

Programming best practices include having automated tests for your code. This is even more important for dynamic languages such as Python—since there is no compilation step, you can't be sure there are no syntactic errors until the interpreter runs the code. A good editor can help us detect some of these problems ahead of time but can't help us ensure the code performs as intended, as automated tests can.

The TDD method states that we should write tests upfront, check that they fail, then develop code that, in the end, should pass the tests. Inspired by this approach, we will add our module tests now before we add the actual features.

Odoo supports automated tests, based on Python's built-in unittest library. Here, we will have a quick introduction to automated tests, and a longer explanation is provided in Chapter 8, Business Logic – Supporting Business Processes.
