# Groggy Documentation Testing Report

## Overview
This report summarizes the testing of all existing Groggy documentation files to identify what works, what needs fixing, and what requires updates.

## Testing Results

### ✅ **Social Network Analysis Tutorial** (`docs/tutorials/social-network-analysis.rst`)

#### **What Works:**
- ✅ Basic graph creation with `gr.Graph()`
- ✅ Node and edge addition with `add_nodes()` and `add_edges()`
- ✅ Node mapping with `get_node_mapping(uid_key='uid')`
- ✅ Table operations: `g.nodes.table()`, `g.edges.table()`
- ✅ Basic analytics: `node_count()`, `edge_count()`, `density()`, `is_connected()`
- ✅ Filtering: `filter_nodes()`, `filter_edges()` with proper filter syntax
- ✅ Table analysis: column access, statistical operations
- ✅ NetworkX export: `to_networkx()`

#### **Issues Found:**
1. **Attribute Access Pattern**: Tutorial uses `node.get('attr')` but should use `node['attr']`
2. **Edge Iteration**: Some loops assume pandas-style iteration which doesn't work
3. **Missing Modules**: Tutorial references `g.centrality.*` and `g.community.*` which don't exist yet (properly marked as TODO)
4. **Table Row Access**: Some examples assume pandas-style `.iterrows()` which doesn't exist

#### **Recommended Fixes:**
```python
# ✗ Wrong (from tutorial)
user_data = g.nodes[user_id]
name = user_data.get('name', 'Unknown')

# ✅ Correct
user_data = g.nodes[user_id]
name = user_data['name']  # or user_data.to_dict()['name']

# ✗ Wrong (from tutorial)
for _, edge in edges_table.iterrows():
    # pandas-style iteration

# ✅ Correct
for i in range(len(edges_table)):
    edge = edges_table[i]
    # process edge
```

### ✅ **Quickstart Guide** (`docs/quickstart.rst`)

#### **What Works:**
- ✅ Basic graph creation
- ✅ Node and edge addition with attributes
- ✅ Table conversion: `g.nodes.table()`
- ✅ Basic table operations

#### **Issues Found:**
1. **String Node IDs**: Quickstart uses `g.add_node("alice", ...)` but Groggy generates numeric IDs
2. **Attribute Access**: Same issue as social tutorial - uses `.get()` instead of dictionary access
3. **Missing Table Features**: References `table(attributes=["age", "role"])` parameter which may not exist

#### **Recommended Fixes:**
```python
# ✗ Wrong (from quickstart)
g.add_node("alice", age=30, role="engineer")
g.add_edge("alice", "bob", relationship="collaborates")

# ✅ Correct
alice = g.add_node(age=30, role="engineer")
bob = g.add_node(age=25, role="designer")
g.add_edge(alice, bob, relationship="collaborates")
```

### ⚠️ **User Guide Documentation** (Critical Issues Found)

#### **`docs/user-guide/graph-basics.rst`** - NEEDS MAJOR FIXES
**Issues Found:**
1. **String Node IDs**: Uses `g.add_node("alice", ...)` instead of storing returned numeric IDs
2. **Non-existent Methods**: References `g.get_node()`, `g.get_edge()`, `g.update_node()`, etc. that don't exist
3. **Wrong Filtering Syntax**: Uses `g.nodes.filter("role == 'engineer'")` instead of proper filter syntax
4. **Non-existent Traversal Methods**: References `g.bfs()`, `g.dfs()` directly on graph
5. **Wrong Connectivity Method**: Uses `g.connected_components()` instead of `g.analytics.connected_components()`

#### **`docs/user-guide/analytics.rst`** - EXTENSIVE ISSUES
**Major Problems:**
1. **Non-existent Centrality Module**: All `g.centrality.*` references fail (betweenness, pagerank, etc.)
2. **Non-existent Community Module**: All `g.communities.*` references fail (louvain, leiden, modularity)
3. **Non-existent Analytics Methods**: References to clustering, assortativity, diameter methods that don't exist
4. **Wrong API Usage**: Many method calls don't match actual implementation

#### **API Documentation Issues**

#### **`docs/api/graph.rst`** - INCONSISTENT WITH REALITY
**Problems:**
1. **Claims centrality module exists** (lines 535-551) but testing shows it doesn't work
2. **Claims communities module exists** (lines 553-568) but testing shows it doesn't work  
3. **Documents methods that don't exist**: `get_node()`, `get_edge()`, `update_node()`, etc.
4. **Wrong filtering syntax**: Documents string-based filtering that doesn't work

#### **Still Need Testing:**
- `docs/user-guide/storage-views.rst`
- `docs/api/analytics.rst`
- `docs/api/array.rst`
- `docs/api/matrix.rst`
- `docs/api/table.rst`

#### **Example Notebooks:**
- `notebooks/SocialMediaAnalysis.ipynb`
- Other `.ipynb` files in notebooks directory

## Common Issues Across Documentation

### 1. **Attribute Access Patterns**
**Problem**: Documentation uses `.get()` method
**Solution**: Use dictionary-style access `node['attr']` or `node.to_dict()['attr']`

### 2. **Node ID Management**
**Problem**: Examples assume string node IDs
**Solution**: Use numeric IDs returned by `add_node()` or use `uid_key` mapping

### 3. **Table Iteration**
**Problem**: Assumes pandas-style `.iterrows()`
**Solution**: Use range-based iteration: `for i in range(len(table)):`

### 4. **Missing Features**
**Problem**: References to unimplemented features without TODO marks
**Solution**: Add proper TODO comments or remove references

### 5. **Import Statements**
**Problem**: Some examples may have incorrect imports
**Solution**: Standardize on `import groggy as gr`

## Recommended Documentation Update Strategy

### Phase 1: **Critical Fixes** (High Priority)
1. ✅ Update social network analysis tutorial with working code
2. ✅ Fix quickstart guide examples
3. ⚠️ **URGENT**: Fix user-guide/graph-basics.rst - contains many non-existent method calls
4. ⚠️ **URGENT**: Fix user-guide/analytics.rst - references non-existent centrality/community modules
5. ⚠️ **URGENT**: Fix api/graph.rst - documents features that don't exist
6. Update attribute access patterns throughout
7. Fix node ID handling patterns

### Phase 2: **Comprehensive Testing** (Medium Priority)
1. Test all user guide examples
2. Test all API documentation examples  
3. Test example notebooks
4. Create working versions of all examples

### Phase 3: **Enhancement** (Low Priority)
1. Add more examples using confirmed working features
2. Create advanced tutorials using new features (boolean indexing, temporal analysis)
3. Add performance optimization guides
4. Create troubleshooting sections

## Working Code Templates

### **Basic Graph Creation**
```python
import groggy as gr

# Create graph
g = gr.Graph()

# Add nodes (returns numeric IDs)
alice = g.add_node(name="Alice", age=30, role="engineer")
bob = g.add_node(name="Bob", age=25, role="designer")

# Add edges
g.add_edge(alice, bob, relationship="collaborates", strength=0.8)

# Basic analysis
print(f"Nodes: {g.node_count()}, Edges: {g.edge_count()}")
print(f"Density: {g.density():.3f}")
```

### **Table Operations**
```python
# Get data as tables
nodes_table = g.nodes.table()
edges_table = g.edges.table()

# Access table data
for i in range(len(nodes_table)):
    row = nodes_table[i]
    name = row['name']  # Direct dictionary access
    age = row['age']
    print(f"{name}: {age} years old")

# Statistical analysis
ages = nodes_table['age']
print(f"Average age: {ages.mean():.1f}")
```

### **Filtering**
```python
# Node filtering
young_people = g.filter_nodes(
    gr.NodeFilter.attribute_filter('age', gr.AttributeFilter.less_than(30))
)

# Edge filtering
strong_relationships = g.filter_edges(
    gr.EdgeFilter.attribute_filter('strength', gr.AttributeFilter.greater_than(0.7))
)
```

### **Attribute Access**
```python
# Node attributes
node = g.nodes[node_id]
name = node['name']           # Dictionary access
all_attrs = node.to_dict()    # Get all as dict
keys = node.keys()            # Get attribute names

# Edge attributes  
edge = g.edges[edge_id]
strength = edge['strength']
edge_dict = edge.to_dict()
```
