Improve ODK-X Services Test Coverage:Write Tests for Data class

[Agaba-derrick]

This issue introduces unit tests for the ColorRule class in the org.opendatakit.data package. The tests aim to verify the correct behavior of the ColorRule methods, including JSON representation, getters, setters, and equality checks.

Test Coverage

• JSON Representation:
  Verifies the correct structure of the JSON object produced by getJsonRepresentation().

• Getters and Setters:
  Tests all getter and setter methods to ensure the proper handling of:

  • columnElementKey
  • val
  • foreground
  • background
  • operator

• Equality Methods:
  Ensures the equals() and equalsWithoutId() methods function as expected:

  • equals() checks full object equality.
  • equalsWithoutId() ignores the rule ID when comparing objects.

• Additional Methods:
  Ensures correct behavior for methods like:

  • getRuleId()
  • getColumnElementKey()
  • And other key logic methods.

Key Test Methods

• testGetJsonRepresentation()
• testGetRuleId()
• testSetVal()
• testEquals()
• testNotEqualsDifferentId()
• testEqualsWithoutId()
• And more...
