json-compare-deep 2.0

Features

• Compare jsons and print the differences (what and where they are, recursion supported). Useful for interface testing.

• Config whether it will ignore the order of items in a list or not, recursively.

• Both python 2.6-2.7 and 3.5-3.9 supported. (New)

• Regular expressions supported for string to skip unconcerned keys or just to assert the format.

• Compact str and unicode (or bytes and str in python3), they are considered equal. Good for non ascii coding languages.

• Both json string (unicode or binary str) and json object (dict, list or tuple) are supported.

• Support tuples, so results from pymysql.cursors.DictCursor can compare with interface response directly.

• Json type legal check(strict_json).

• Support skipping anywhere using argument like ignore_path=[“/a/1/k”, “/a/1/l”], dict keys or list indexes. Skipped fields are regarded as match.

• The ignore_path list now support regular expressions too. You can use [r“^(/:raw-latex:`d+`/a)”] as ignore_path to skip all keys named “a” in [{“a”: 1, “b”: 2}, {“a”: 1, “b”: 4}] but still compare the value of “b”. (New)

  • Useful when compare multi records in database query result (dictionary cursor) with some fields unconcerned.

• Fuzzy equal when handling floats.

• Custom handlers supported.

• Strict_number_type option to make int(1) != float(1.0) supported.

• Emit keys in dict compare supported. (New)

QuickStart

install

pip install jsoncomparedeep

or update

pip install -U jsoncomparedeep

a simple example

from json_compare import compare
print(compare({"key1":["v1","v2"],"key2":{"key3":1}},{"key1":["v2","v1"],"key2":{"key3":2}}))

to see

a is {'key1': ['v1', 'v2'], 'key2': {'key3': 1}}
b is {'key1': ['v2', 'v1'], 'key2': {'key3': 2}}
ignore_list_seq = True, re_compare = True, ignore_path = None, omit_path = None, float_fuzzy_digits = 0
different value at /key2/key3
a: 1
b: 2
False

For more demos and information, just install it and visit the test file test_json_compare.py in Your_Python_Path/Lib/site-packages/json_compare/

Small Hints

• Datetime in SQL result is not JSON serializable type, use something like CAST(create_time as CHAR) ‘create_time’ in SQL statement to solve it.
