feat: Add tests for RobotsNode and update test setup

- Added pytest fixture to set up the RobotsNode with the initial state. - Implemented test_robots_node to test the execution of RobotsNode. - Used unittest.mock.patch to mock the execute method, ensuring faster and more reliable tests without actual network calls. - Added assertions to verify the correctness of the result and ensure the execute method is called once with the correct arguments.
