Add Tests Skill

Generate test scaffolding for untested modules in Panoptes.

Steps

1. Analyze the target module

   • Read the source file
   • Identify public functions and their signatures
   • Note any complex logic or edge cases

2. Determine testable components

   • Pure functions (no side effects)
   • State transitions
   • Type conversions
   • Validation logic
   • Filter/search functions

3. Generate test scaffolding Add a #[cfg(test)] block at the end of the module:

   #[cfg(test)]
   mod tests {
       use super::*;
   
       // Helper functions for creating test fixtures
       fn create_test_item() -> ItemType {
           // ...
       }
   
       #[test]
       fn test_function_name_basic() {
           // Arrange
           let input = create_test_item();
   
           // Act
           let result = function_name(input);
   
           // Assert
           assert_eq!(result, expected);
       }
   
       #[test]
       fn test_function_name_edge_case() {
           // Test edge cases
       }
   }
   

4. Test categories to include

   • Happy path: Normal expected usage
   • Edge cases: Empty inputs, boundaries, special values
   • Error cases: Invalid inputs, error conditions
   • State transitions: Before/after state changes

Panoptes-Specific Patterns

Testing State Navigation

#[test]
fn test_navigate_to_project() {
    let mut state = AppState::default();
    let project_id = uuid::Uuid::new_v4();

    state.navigate_to_project(project_id);

    assert_eq!(state.view, View::ProjectDetail(project_id));
    assert_eq!(state.selected_branch_index, 0);
}

Testing Filters

#[test]
fn test_filter_empty_query() {
    let items = create_test_items();
    let filtered = filter_items(&items, "");
    assert_eq!(filtered.len(), items.len());
}

#[test]
fn test_filter_case_insensitive() {
    let items = create_test_items();
    let filtered = filter_items(&items, "MAIN");
    assert!(filtered.iter().any(|i| i.name == "main"));
}

Testing Enums

#[test]
fn test_event_type_roundtrip() {
    for event_type in [EventType::A, EventType::B, EventType::C] {
        let str_repr = event_type.as_str();
        let parsed: EventType = str_repr.into();
        assert_eq!(parsed, event_type);
    }
}

Common Dependencies

Tests often need:

use tempfile::TempDir;  // For filesystem tests
use uuid::Uuid;          // For ID generation

Output

After running this skill, you should have:

1. A #[cfg(test)] module with tests
2. Tests for all public functions
3. Edge case coverage
4. Verifiable assertions (not just assert!(true))
