Unit Tests

Unit tests focus on testing individual functions and classes in isolation, ensuring that each component behaves correctly under various conditions.

Overview

The unit test suite covers core hazelbean functionality including:

  • Path Resolution - Testing file path handling and resolution logic
  • Array Framework - Testing the ArrayFrame data structure and operations
  • Core Utilities - Testing utility functions and helper methods
  • Data Structures - Testing custom data types and containers
  • Geospatial Operations - Testing fundamental geospatial processing functions

Path Resolution Testing

Tests for file path handling, validation, and resolution across different operating systems.

Key Test Cases Covered:

  • test_file_in_current_directory() - Resolves files in project root
  • test_file_in_intermediate_directory() - Finds files in intermediate folders
  • test_file_in_input_directory() - Locates input data files
  • test_raster_file_resolution() - Handles .tif/.tiff raster formats
  • test_vector_file_resolution() - Processes .gpkg/.shp vector files
  • test_csv_file_resolution() - Manages .csv data files
  • test_pyramid_data_resolution() - Accesses pyramid datasets
  • test_none_input_handling() - Gracefully handles None inputs
  • test_empty_string_input() - Validates empty string behavior
  • test_invalid_characters_in_path() - Rejects invalid path characters
  • test_google_cloud_bucket_integration() - Cloud storage integration
  • test_bucket_name_assignment() - Cloud bucket configuration

Unit tests for ProjectFlow.get_path() functionality

This test suite covers: - Local file path resolution - File format handling - Error handling and edge cases - Directory prepending functionality - Cloud storage integration - Integration with existing data directories

Array Framework Testing

Comprehensive tests for the ArrayFrame class, which provides enhanced array operations for geospatial data.

Key Test Cases Covered:

  • test_arrayframe_load_and_save() - Load, process, and save geospatial arrays
🔧 Helper Methods (Click to expand)

These are setup and utility methods used by the test class:

  • setUp() - Hook method for setting up the test fixture before exercising it
  • tearDown() - Hook method for deconstructing the test fixture after testing it
  • delete_on_finish() - Custom cleanup method for test data

Tile Iterator Testing

Tests for efficient iteration over large raster datasets using tiling strategies.

Unit tests for Hazelbean tiling iterator functionality

This test suite covers: - Basic iterator instantiation and configuration - ProjectFlow iterator creation and execution - Directory structure handling for tiles - Parallel processing flag configuration - Workflow execution validation - Spatial tiling bounds calculations - Geographic coordinate tiling logic - Tile boundary completeness and edge cases - Raster simulation with tiling - Coordinate transformations - Spatial integration with ProjectFlow

Running Unit Tests

To run the complete unit test suite:

# Activate the hazelbean environment
conda activate hazelbean_env

# Run all unit tests
pytest hazelbean_tests/unit/ -v

# Run specific test file
pytest hazelbean_tests/unit/test_get_path.py -v

# Run with coverage
pytest hazelbean_tests/unit/ --cov=hazelbean --cov-report=html

Test Coverage

Unit tests aim for comprehensive coverage of:

  • Happy path scenarios - Normal usage patterns
  • Edge cases - Boundary conditions and unusual inputs
  • Error conditions - Invalid inputs and exception handling
  • Cross-platform compatibility - Different operating systems
  • Performance characteristics - Memory usage and execution time
  • Integration Tests → See how unit-tested components work together in Integration Tests
  • Performance Tests → Review performance implications in Performance Tests
  • System Tests → Validate complete system behavior in System Tests
