Use Integration Tests For Get Operations

[Torres-ssf]

The current tests for the get operations functionality are unit tests, which rely on a significant amount of mocked/fake data.

Due to the nature of unit tests—isolating many components and requiring extensive setup—and the complexity of simulating all operations (which involves executing multiple types of transactions), we need to replace these unit tests with integration tests.

Using integration tests will provide greater confidence that all operations are being properly extracted as expected.
