43-44: Great addition of edge case tests!Testing behavior with invalid indices is essential for robust code. These assertions verify that the Path class gracefully handles out-of-bounds scenarios by returning None instead of raising exceptions.

💡 Verification agent
🧩 Analysis chain
Verify the expected string representation format.
The test checks for a specific string format, but I can't verify if it matches the actual implementation without seeing the Path class's __str__ method. Ensure that the hardcoded string "<(node1)-(edge1)->(node2)>" matches how nodes and edges are actually represented when converted to strings.
🏁 Script executed:
#!/bin/bash
# Check the __str__ implementation in the Path class
grep -A 10 "__str__" $(fd "path.py" --type f --exclude "test_path.py")Length of output: 425
I want to confirm the full __str__ logic to ensure the test’s expected output matches exactly. Let's dump the entire method:
🏁 Script executed:
#!/bin/bash
grep -n "def __str__" -A 200 falkordb/path.pyLength of output: 864
I’d like to verify how nodes and edges are set up in the test (their IDs and types). Dumping the relevant portion of tests/test_path.py:
🏁 Script executed:
sed -n '1,200p' tests/test_path.pyLength of output: 1712
I’d like to inspect how Node.id and Edge.id are defined to confirm the string formatting. Dump the class definitions:
🏁 Script executed:
#!/bin/bash
grep -n "class Node" -A 50 falkordb/node.py
grep -n "class Edge" -A 50 falkordb/edge.pyLength of output: 3375
Let’s inspect the __str__ implementations for both Node and Edge to confirm how they format IDs and aliases:
🏁 Script executed:
#!/bin/bash
grep -n "def __str__" -A 20 falkordb/node.py
grep -n "def __str__" -A 20 falkordb/edge.pyLength of output: 1409
To confirm how equality and the edge’s __str__ tail behave, let’s dump any __eq__ methods and the rest of the Edge.__str__ implementation:
🏁 Script executed:
#!/bin/bash
# Check for __eq__ in Node and Edge
grep -R "def __eq__" -n falkordb/node.py falkordb/edge.py || echo "No __eq__ methods found"
# Dump full Edge.__str__ method
sed -n '57,120p' falkordb/edge.pyLength of output: 1925
Mismatch between test’s expected format and Path.str implementation
The Path.__str__ method builds its output using the numeric id values and square brackets around edge IDs, e.g.
"<(1)-[1]->(2)>"However, the test asserts:
assert str(p) == "<(node1)-(edge1)->(node2)>"– which doesn’t align with the implementation.
Please update the test in tests/test_path.py accordingly:
- When creating the edge, supply an integer ID:
- edge_1 = Edge(node_1, None, node_2)
- edge_1 = Edge(node_1, None, node_2, edge_id=1)
- Change the expected string to match `Path.__str__`’s output:
```diff
- assert path_str == "<(node1)-(edge1)->(node2)>"
+ assert path_str == "<(1)-[1]->(2)>"
