Lessons learned

Clemens:

• Learning to send Json through the message Queue
• How to create Json in Java
• Creative thinking of how to pack and unpack data which is sent through the Queue
• How the distributed parts of the System work as one
• Using SQL in Java

Nico:

• Access databases with Java (JDBC)
• Create artifacts from Java code (PDF)
• Connect different services through implementing a MQ
• Develop "loosely" coupled services
• Test code through Unit Tests

Florian:

• Learning how to programm a API wich can be called by another Program (JavaFx)
• Implementing different programms, wich are communicating just over the message Queue
• Find out how so send and handle POST Requests with Springboot
• Learn how to build a frontend program with JavaFx, which does something in the background, without knowing what exactly.
• Learned how to use Docker

Unit test decisions

shouldReturnSpecificCustomer - PDFGenerator

This unit test was chosen/created to verify the correctness of the getCustomerFromDB method in the GeneratorService class. By setting up an expected customer with known values and comparing it to the actual customer returned by the method, we can verify the accuracy of the database connection and query execution.

shouldReturnTotalAmount - PDFGenerator

This test aims to verify the accuracy of the getTotalAmount method in the GeneratorService class. The test helps us to see whether the method correctly calculates the total amount based on the charge information provided. This ensures that the correct amount is written into the PDF.

shouldConvertJsonProperly - StationDataCollector

At last, the advantage of implementing this test is to ensure that the convertToJson method in the ServiceSDC class correctly converts a list of ChargeInfoSDC objects into the expected JSON format. It helps us to see if the data is correctly sent to the subsequent services, which is crucial for their further processing.
