What is TDD in D365 F and O?

Test-Driven Development (TDD)

TDD in D365 F&O refers to Test-Driven Development in Dynamics 365 Finance and Operations. Test-Driven Development is a software development practice that emphasizes writing automated tests before writing the actual code. In the context of D365 F&O, TDD involves creating tests for specific functionalities or business processes within the application and then writing code to fulfill those tests.

With TDD, the development process starts by defining the desired behavior or requirements of a feature through test cases. These test cases are written in a way that verifies the expected behavior of the feature. Once the test cases are defined, developers write the code to pass these tests. This approach ensures that the code is built to meet the desired requirements and helps prevent regressions or unintended changes in functionality as the codebase evolves.

In D365 F&O, TDD can be applied to various areas, such as customizations, extensions, integrations, and business process automation. By following TDD principles, developers can have a structured and reliable approach to building and maintaining the system, ensuring that changes and updates are thoroughly tested and meet the expected outcomes.

Overall, TDD in D365 F&O helps improve the quality of the solution, reduces the risk of introducing defects, and provides a solid foundation for continuous integration and deployment practices.

Technical Design Document (TDD)

In the context of D365 F&O (Dynamics 365 Finance and Operations), TDD can also refer to the Technical Design Document. The Technical Design Document is a document that outlines the technical specifications and details of a solution or development project within D365 F&O.

The TDD serves as a comprehensive guide for developers, technical consultants, and stakeholders involved in the implementation or customization of D365 F&O. It typically includes the following information:

1. Solution Overview: This section provides an overview of the solution or project, including its objectives, scope, and key functionalities.

2. Architecture: The TDD describes the system architecture and technical infrastructure required for the solution, including hardware, software, databases, and integration components.

3. Data Model: It outlines the structure and relationships of the data entities and tables within D365 F&O that are relevant to the solution.

4. Business Logic: This section covers the technical design and implementation details of the business rules, workflows, calculations, and processes within the solution.

5. User Interface: The TDD specifies the user interface design and layout, including forms, fields, menus, and navigation within D365 F&O.

6. Integration: If the solution requires integration with external systems or services, the TDD outlines the integration requirements, protocols, and interfaces.

7. Customizations and Extensions: It describes any custom code, extensions, or modifications to the standard functionality of D365 F&O, along with the associated technical specifications.

8. Security: This section covers the security model and access controls for the solution, including user roles, permissions, and data privacy considerations.

9. Performance and Scalability: The TDD may include guidelines and recommendations for optimizing the performance and scalability of the solution within D365 F&O.

10. Testing and Validation: It outlines the testing strategy, test scenarios, and acceptance criteria for validating the solution's functionality and quality.

The Technical Design Document serves as a reference and communication tool between technical teams, project managers, and stakeholders, ensuring a shared understanding of the technical aspects of the solution and guiding the development process within D365 F&O.
