See files Changed section

These changes have increased the Sonar coverage from the 15% achieved with the exception unit test PR #2348 (9.45% overall). These tests were written last week and debugged this week. The PR has been released after the approval of the exception unit test PR on 2023-12-04.

Preview

Overall sonar coverage has increased to 50%, from 0%, for organization service model entity.

The Sonar coverage increase for model/mapper:

The goal was to get organization-service > 30% and I will confirm this once the PR has been merged. Given that the Sonar coverage calculation is 15% higher than the intended coverage it's possible that the Code Quality Dashboard will reflect 30% code coverage with the updates made to this class.

@tschaffter Do you feel this covers #1528? Or were you thinking about another class when creating this? This is intended to be reviewed after #2388 but were created during the same week.

Changes implemented:

1. Updated organizationEntity to entity in tests with a single entity
2. Changed all occurrences of retrieved in variable names to actual
3. TBD on how to implement @BeforeAll w/o throwing errors

Changes made to condense the code and avoid repitition led to a slight increase in Sonar coverage for to 51%.

Organization entity properties, login and email, were removed during PR #2399 which caused the OrganizationEntityTest.java unit tests to fail. Removed the unit tests related to the Organization Entity login and email properties. Sonar coverage was reduced to 48%.

@tschaffter This is ready for you to review. I made the changes you asked for:

Implemented the following changes:

1. Changed the unit test name from EqualsObject_ShouldReturnBoolean_WhenPassedTwoObjects to EqualsObject_ShouldBeTheSame_WhenPassedTwoIdenticalObjects
2. Separated that test into 2 smaller tests 1 test differentiates between two different objects and the other recognizes two objects as being identical.

I tried to push changes to this PR but git didn't offer me this option unlike when attempting to push to Verena's and Rong's PR. I wanted to delete the file that only include commented content. I will now merge this PR and make the change later.
