This test plan aims to ensure the robustness, reliability, and compliance of processes for downloading, processing, and ingesting the Hugging Face dataset into SQLite3. By implementing Test-Driven Development (TDD), we create a comprehensive suite of granular tests covering all critical functionalities of the data pipeline. These tests are organized into structured directories to enhance maintainability.
- Validate dataset download: Ensure successful download from Hugging Face.
- Verify PDF text extraction: Confirm accurate text extraction from PDF files.
- Test dataset processing: Ensure correct processing into a DataFrame.
- Validate data ingestion: Confirm correct insertion into the SQLite3 database.
- Ensure data cleaning accuracy: Validate operations such as removing duplicates and handling missing values.
- Confirm data transformation: Validate operations like merging datasets, enriching data, and deriving new features.
- Verify data validation: Ensure schema validation and data integrity checks.
- Quality assurance: Verify the final dataset meets quality standards and performance metrics, incorporating user feedback.
The tests are organized into the following directory structure:
tests/
├── dataset/ # Tests related to dataset operations
│ ├── test_download.py # Tests focused on downloading the dataset
│ ├── test_extract.py # Tests focused on extracting text from PDFs
│ ├── test_process.py # Tests focused on processing the dataset
│ └── test_ingest.py # Tests focused on ingesting the dataset into SQLite3

Objective: Verify successful download and integrity of the dataset from Hugging Face.
Objective: Ensure accurate text extraction from PDF files.
Objective: Confirm the dataset is processed correctly into a DataFrame.
Objective: Validate that processed data is correctly inserted into the SQLite3 database.
Objective: Ensure accuracy of data cleaning operations like removing duplicates and handling missing values.
Objective: Confirm that data transformation operations like merging datasets, enriching data, and deriving new features are performed correctly.
Objective: Validate the schema and integrity of the data, ensuring consistency across subsets.
Objective: Verify the final dataset meets quality standards and performance metrics, incorporating user feedback.
To run the tests, navigate to the root of your project directory and use the following command:
pytest tests/
This command runs all the tests in the specified directory, ensuring that each component of the data pipeline functions as expected.
By implementing granular and focused tests organized in a clear directory structure, we ensure that our data pipeline is thoroughly validated at each stage. This approach helps maintain code quality, prevent bugs, and facilitate future enhancements.
