Critical Patterns (Detailed)

small_graph

This pattern provides a predefined small graph for testing purposes, allowing for consistent and repeatable tests.

# Example usage of small_graph
from tests.test_graph import small_graph

def test_small_graph():
    assert len(small_graph.nodes) == expected_node_count

TestAddNode

This pattern tests the functionality of adding a node to the graph, ensuring that the graph updates correctly.

# Example usage of TestAddNode
from tests.test_graph import TestAddNode

def test_add_node():
    test_case = TestAddNode()
    test_case.run()

When to Use

• When you need to create a small graph for unit tests.
• When testing the addition of nodes to a graph structure.

Commands

pytest tests/test_graph.py

Anti-Patterns

Don't: Use real RepoMaps in tests

Using real RepoMaps can lead to flaky tests and inconsistent results.

# BAD
from repo.maps import RepoMap

def test_with_real_repos():
    repo = RepoMap()
    assert repo is not None
