testindex-knowledge-contract 0.1.0

Knowledge v1 Contract for TestIndex

TestIndex Knowledge Contract

This package provides the minimal contract interface for working with Knowledge v1 data, designed for other internal testing tools to build on top of the Knowledge v1 system.

Installation

There are two ways to install the package:

1. Local Installation (Recommended)

Install the package directly from the included wheel file:

# From within this repository
pip install testindex_knowledge_contract/dist/testindex_knowledge_contract-0.1.0-py3-none-any.whl

# OR using absolute path (works from any directory)
pip install /Users/btsznh/kine/vsearch/testindex_knowledge_contract/dist/testindex_knowledge_contract-0.1.0-py3-none-any.whl

2. GitHub Release (Not currently working)

# NOTE: There are currently issues with the GitHub release.
# Please use the local installation method above instead.
pip install https://github.com/thusai/testindex-graph/releases/download/v0.1.0/testindex_knowledge_contract-0.1.0-py3-none-any.whl

Or add to requirements.txt:

# For now, it's recommended to use a local path to the wheel file
# instead of this PyPI reference
testindex-knowledge-contract==0.1.0

Local Development

If you need to rebuild the package:

# Activate your virtual environment first
source venv/bin/activate

# Build the wheel
cd testindex_knowledge_contract
bash build_wheel.sh

# Install the freshly built wheel
pip install dist/testindex_knowledge_contract-0.1.0-py3-none-any.whl

# OR using absolute path (works from any directory)
pip install /Users/btsznh/kine/vsearch/testindex_knowledge_contract/dist/testindex_knowledge_contract-0.1.0-py3-none-any.whl

Components

The package contains four main components:

1. Schema Constants - Node labels and property names
2. Neo4j Client - Minimal interface for Neo4j access
3. Benchmark Constants - For consistent testing
4. Gold Sample - For precision validation

Usage

Schema Constants

from testindex_knowledge_contract.schema import (
    IMPL_LABEL, GAP_LABEL, PROP_ID, PROP_PATH, PROP_START, PROP_END, PROP_COVER
)

# Example: Use schema constants in a query
query = f"MATCH (n:{IMPL_LABEL}) WHERE n.{PROP_COVER} < 50 RETURN n"

Neo4j Client

from testindex_knowledge_contract.neo4j_client import Neo4jClient

# Connect using environment variables (NEO4J_URI, NEO4J_USER, NEO4J_PASS)
client = Neo4jClient()

# Or connect with specific credentials
client = Neo4jClient(
    uri="bolt://localhost:7687",
    username="neo4j",
    password="password"
)

# Run a query
results = client.run_query(
    "MATCH (n:Implementation) WHERE n.coverage < $threshold RETURN n",
    {"threshold": 50}
)

# Results are returned as a list of dictionaries
for record in results:
    print(record)

Using Benchmark Constants

from testindex_knowledge_contract.bench_constants import DJANGO_SHA, PATCH_FILE

print(f"Using Django at commit: {DJANGO_SHA}")
print(f"With test patch: {PATCH_FILE}")

Using Gold Schema for Testing

import json
import importlib.resources
from testindex_knowledge_contract import test_data

# Access the gold schema data
gold_schema_path = importlib.resources.files(test_data).joinpath('gold_schema.json')
with open(gold_schema_path, 'r') as f:
    gold_schema = json.load(f)

# Use gold schema for precision testing
print(f"Gold schema has {len(gold_schema['nodes'])} nodes and {len(gold_schema['edges'])} edges")

Example: Coverage Map 360 Integration

from testindex_knowledge_contract.schema import (
    IMPL_LABEL, GAP_LABEL, PROP_ID, PROP_PATH, PROP_START, PROP_END, PROP_COVER
)
from testindex_knowledge_contract.neo4j_client import Neo4jClient

# Create client
client = Neo4jClient()

# Query uncovered implementation functions
query = f"""
MATCH (n:{IMPL_LABEL})
WHERE n.{PROP_COVER} < 10
RETURN n.{PROP_ID} as id, n.{PROP_PATH} as path, n.{PROP_START} as start_line, n.{PROP_END} as end_line
"""

results = client.run_query(query)

# Process results
for record in results:
    print(f"Low coverage detected: {record['path']} (lines {record['start_line']}-{record['end_line']})")
