Odoo supports different ways of writing addon module tests, YAML tests, and Python tests. In this recipe, we will see how to write YAML tests for the my_module methods we wrote in Chapter 5, Basic Server Side Development, in the recipe Define Model methods and use the API decorators.

Getting ready

This recipe assumes you have an instance ready with the code for the my_module module defined in Chapter 3, Creating Odoo Modules, and the code from the Define Model methods and use the API decorators recipe in Chapter 5, Basic Server Side Development.
