#2947

Description

This PR aims to add a new test to the Wazuh QA repository of the new development of the core team. The EPS limits development reduces the load of events processes by creating a circular buffer.

Good first approach. However, there are multiple changes and pending conversations to resolve.
The most important changes to apply are the following:

• Change the framework in order to not affect the rest of the testing module (Agent simulator and simulate agents )
• Ensure the logcollector is disabled in the environment
• Refactor methods when proceeding
• Use name conventions of the repository

Detected error in simulate_agent fixture. In case of not running tests with python3 (for example running python3.10) all tests that make use of simulate agent script fail. I have talked with @fedepacher in order to avoid if possible this case.

All tests and frameworks have been refactored because they were unstable and not optimized.

The tests documentation can be found in the docstrings of the implemented test modules.
