接口自动化，断言方法，深度定位错误。

 

代码如下：

 1 #!/usr/bin/env python
 2 # -*- coding: utf-8 -*-
 3 # @Time    : 2017-07-27 13:49
 4 
 5 # 断言方法，比较两个list或dict的不同之处

 7 a= {‘b‘:[1,2,5,8],‘c‘:3,‘d‘:2,‘f‘:[1,2,3],‘g‘:[1,2,3,[2,‘2‘,2]],‘h‘:‘5‘}
 8 b= {‘b‘:[1,2,‘3‘],‘c‘:2,‘e‘:‘4‘,‘f‘:[1,2,3,5],‘g‘:[1,2,3,[1,2]],‘h‘:[1,2]}

10 def compare_json_data(A, B, L = [], xpath = ‘.‘):
11     if isinstance(A, list) and isinstance(B, list):
12         for i in range(len(A)):
13             try:

29                 continue
30             compare_json_data(A.get(i), B.get(i), L, xpath + ‘/‘ + str(i))
31         return

38 def Assert(A,B):
39     C = []
40     compare_json_data(A, B, C)
41     assert len(C) == 0, "\\n"+"".join(C)
42 Assert(a, b)

效果图如下：
