Avoid the use/creation of real databases in the UTs. #570

Nicogp · 2025-02-03T21:24:36Z

Description

This PR adds the necessary changes to avoid the use and/or creation of the agent_info.db database in the UTs.

Proposed Changes

The Persistence interface is used to declare a mock class(MockPersistence) that implements this interface in order to mock the methods used by AgentInfoPersistance

The changes include:

Creation of class MockPersistence
Changes in the constructor of AgentInfoPersistance to be able to inject the object of the MockPersistence class.
Creating UTs for AgentInfoPersistance
Changes in the constructor of AgentInfo, AgentRegistration and Agent to be able to inject an object of the AgentInfoPersistance class created with the MockPersistence object injection.
Correction of AgentInfo, AgentRegistration and Agent UTs

Results and Evidence

I'm wondering if we are doing the correct thing here by testing AgentInfo and AgentInfoRegistration with a mocked persistence class. The specific of the persistence implementation should be a detail visible only to AgentInfoPersistence, who uses it. In some of these tests we are actually testing the certain Persistence functions are being called, which I believe should be beyond the concerns of AgentInfo and AgentInfoRegistration. Maybe it would be more correct to test AgentInfo with a mocked AgentInfoPersistence, and to test AgentInfoRegistration with a mocked AgentInfo? Perhaps you already evaluated this, let me know what you think.

We should check all ocurrences of "persistance" and change it to "persistence" to keep some consistency

Hi @jr0me, I have created another issue to work on this.

I'm wondering if we are doing the correct thing here by testing AgentInfo and AgentInfoRegistration with a mocked persistence class. The specific of the persistence implementation should be a detail visible only to AgentInfoPersistence, who uses it. In some of these tests we are actually testing the certain Persistence functions are being called, which I believe should be beyond the concerns of AgentInfo and AgentInfoRegistration.
