mismatcha 0.1.1

Yes, another compare tool

A tool for comparison of JSON-like structures.

It recursively walks through both structures and reports any mismatches found, such as:

• missing keys in dict
• type mismatch
• value mismatch
• list length difference

---

Usage:

Call:

d1 = {
    "user": {
        "id": 512341,
        "name": "Alex",
        "active": True,
        "score": 4.5,
        "tags": ["qa", "python", {"extra": False}]
    }
}

d2 = {
    "user": {
        "id": 6512,
        "active": "yes",
        "score": 4.5,
        "tags": ["qa", "python", {"extra": True}]
        "extra_param": "boo!"
    }
}

compare(expected=d1, actual=d2, ignore=["user.tags.extra"])

Output:

[user.id] Value mismatch 
Expected: 512341 (int) 
Actual: 6512 (int)

[user.name] Param not found 
Expected: name (str) 
Actual: None (NoneType)

[user.active] Type mismatch 
Expected: True (bool) 
Actual: yes (str)

Comparison rules:

• dicts are compared only by keys present in the expected structure (extra keys in the actual will be ignored)
• lists are compared by index (order matters)
• int and float are treated as compatible numeric types
• Anything other than dict/list will be compared as is.
