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.
