How do you organize testing during development when you start sending a new field to another team?

When adding a new field that is sent to another team, it is important to structure testing to minimize risks and ensure correct integration.

1. Discussion of requirements and contracts: First, agree with the receiving team on the format and purpose of the new field to avoid misunderstandings.

2. Unit tests: Write tests that verify the correct formation and sending of the new field in outgoing messages or APIs.

3. Integration tests: If possible, set up tests that check the interaction between teams, for example, through mock services or test environments.

4. Contract testing: Use contract testing approaches (e.g., Pact) to ensure that changes do not violate agreements between services.

5. Manual testing and communication: Conduct joint testing with the other team to ensure that the new field is processed correctly.

6. Post-release monitoring: Set up monitoring and logging to quickly detect possible issues in production.

This approach ensures quality and reduces risks when making changes that affect team interactions.
