示例1: test_remove_connected_vertex
# 需要导入模块: from graphs import Graph [as 别名]
# 或者: from graphs.Graph import connected_vertex [as 别名]
def test_remove_connected_vertex(self):
"""Tests the remove_vertex method for a connected vertex.
"""
data = { 'A' : ['B'], 'B' : ['A'] }
graph = Graph(graph=data)
self.assertTrue('B' in graph.connected_vertex('A'), 'There is an edge between A and B.')
self.assertTrue('A' in graph.connected_vertex('B'), 'There is an edge between A and B.')
graph.remove_vertex('A')
self.assertFalse('A' in graph.connected_vertex('B'), 'No more edge between A and B.')示例2: test_add_vertex_existing_one
# 需要导入模块: from graphs import Graph [as 别名]
# 或者: from graphs.Graph import connected_vertex [as 别名]
def test_add_vertex_existing_one(self):
"""Tests the add_vertex method in a graph where the vertex to add already exists.
