# Test Plan for `ColorFeaturesPyramid`
|
|
|
|
## Overview
|
|
This document outlines the plan for testing and documenting the `ColorFeaturesPyramid` class.
|
|
|
|
## 1. Understanding the `ColorFeaturesPyramid` Class
|
|
- The `ColorFeaturesPyramid` class performs pyramid down-sampling and color feature analysis on images.
|
|
- It relies on the `ColorFeaturesTile` class for tile-based analysis.
|
|
- Key parameters:
|
|
- `uuid`: Identifier for the image.
|
|
- `tilew` and `tileh`: Dimensions of the tiles for analysis.
|
|
- `down_sampling`: Number of down-sampling levels.
|
|
- `colorspace`: Color space for analysis (e.g., `lab`, `rgb`, `hsv`).
|
|
- The class reads an image, down-samples it, and analyzes the tiles at each level.
|
|
|
|
## 2. Design the Test Function
|
|
### Test Scope
|
|
Unit tests to verify the functionality of the `ColorFeaturesPyramid` class.
|
|
|
|
### Test Cases
|
|
1. **Initialization Test**:
|
|
- Verify that the class initializes correctly with default and custom parameters.
|
|
- Ensure that the `check_params` function from `utils.py` is used correctly.
|
|
2. **Down-Sampling Test**:
|
|
- Verify that the down-sampling process works as expected.
|
|
- Check that the down-sampled images are saved correctly.
|
|
3. **Tile Analysis Test**:
|
|
- Verify that the tile analysis produces the expected output.
|
|
- Ensure that the histograms are computed correctly.
|
|
4. **Edge Cases**:
|
|
- Test with invalid inputs (e.g., non-existent image, invalid color space).
|
|
- Test with extreme values for parameters (e.g., very large or small tile sizes).
|
|
|
|
### Testing Framework
|
|
Use `pytest` for writing and running the tests.
|
|
|
|
## 3. Document the Test Function
|
|
- Write clear docstrings for the test function.
|
|
- Include examples of how to use the `ColorFeaturesPyramid` class.
|
|
- Document the expected behavior and assumptions.
|
|
- Add comments to explain the purpose of each test case.
|
|
|
|
## 4. Plan the Implementation
|
|
- Create a new test file: `test_color_features_pyramid.py`.
|
|
- Implement the test function and test cases.
|
|
- Ensure the test function is modular and reusable.
|
|
- Use the `check_params` function from `utils.py` to validate parameters.
|
|
|
|
## 5. Verify the Plan
|
|
- Review the plan to ensure all aspects are covered.
|
|
- Confirm that the test function aligns with the purpose of the `ColorFeaturesPyramid` class. |
