About Project
AI-powered web platform that transforms natural language queries into SQL requests to simplify access to business data and streamline BI analytics.
Before
- Before our QA joined the project, testing was conducted by the development team.
- There was testing documentation in the form of a checklist, and no visual references to guide UI validation.
- AI responses often missed the point of user queries, and inconsistencies in SQL logic led to unpredictable results.
Challenges and Solutions
Challenges
- AI responses lacked consistency; identical queries to AI often resulted in outputs with different SQL logic.
- The absence of UI mockups made it challenging to validate interface elements precisely.
- There was no detailed documentation to guide the testing process.
- Lack of reference outputs made verifying the correctness of AI-generated responses challenging.
Solutions
- We designed flexible test cases to validate SQL logic relevance rather than exact SQL templates.
- SQL queries were manually validated using DBeaver to check both logic and data accuracy in responses.
- Clear UI issues were reported through bug reports.
- We compiled a complete documentation set, including a test strategy and a detailed test plan with test cases.
Technologies, Tools, and Approaches
- DBeaver is used to validate SQL queries and ensure the accuracy of database responses.
- Browsers: Google Chrome was the primary browser for functional and UI testing, and Firefox and Safari were also used for cross-browser compatibility checks.
- Xbox Game Bar / Zoom is used for screen recording and capturing defects.
- Slack served as the main channel for direct team communication.
- Jira and Confluence are used for task tracking, documentation management, and storing test cases.
Testing Approaches
- Developed and documented regression testing scenarios to cover critical user flows and system functionalities.
- Maintained a list of failed or inaccurate SQL queries as a supporting artifact for root cause analysis and AI model improvement.
- Conducted UI/UX testing without design mockups, relying on UX best practices, interface consistency, and common sense.
Features of the Project
- There was a high tolerance for variation in correct answers. Due to AI's generative nature, multiple SQL queries could produce equally valid results.
- Test cases tailored for working with generative AI, focusing on SQL logic relevance rather than exact query structure.
Results
- Over 200 detailed test cases were created to verify AI-generated SQL queries and UI functionality.
- Up to 150 bugs were reported.
- The accuracy of AI responses improved by up to 40%—the system started generating answers that matched the intent of the user's questions.
- The probability of receiving incorrect or logically irrelevant SQL queries decreased.
- AI passed the red teaming review after the final testing cycle.
- Response generation became more consistent across similar queries.
- A complete QA documentation package was delivered: a test strategy and detailed test plan with test cases.
- The client gained better visibility into product quality and a structured foundation for further development and quality control.
