1df53a87f4* refactor: add test for sorting vertices in unconnected graph Add a new test case to the `test_get_sorted_vertices_with_unconnected_graph` function in the `test_utils.py` file. This test verifies the correct sorting of vertices in an unconnected graph. The test defines a graph structure and checks that the first layer contains the input vertices and the remaining layers contain the rest of the vertices in the correct order. Refactor the code to improve test coverage and ensure the correctness of the sorting algorithm. * refactor: improve handling of unconnected vertices in graph sorting * [autofix.ci] apply automated fixes * Refactor: Update start_component_id in test_get_sorted_vertices_with_unconnected_graph The start_component_id parameter in the test_get_sorted_vertices_with_unconnected_graph function was updated to "A" to improve the handling of unconnected vertices in graph sorting. * Refactor: Improve handling of unconnected vertices in graph sorting * [autofix.ci] apply automated fixes * Refactor: Add test_filter_vertices_from_vertex function to test_utils.py * Refactor: Add error handling for missing graph information in filter_vertices_up_to_vertex and filter_vertices_from_vertex functions * [autofix.ci] apply automated fixes --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> |
