For example, if you're looking for information on a celebrity, your search might look like this:

| Component | Description | Key Interactions | |-----------|-------------|------------------| | Live Feed | Chronological list of Milena’s tweets with media preview. | Click to expand, share, open on X. | | Analytics Dashboard | Graphs for: | Time‑range selector, export CSV. | | Keyword Alerts | User‑defined keywords (e.g., “conference”, “launch”). | Push notification (web, mobile, email) when a new tweet contains a keyword. | | Sentiment Overlay (optional) | Basic sentiment (positive/neutral/negative) using a lightweight NLP library (e.g., VADER). | Toggle overlay on the feed. | | Settings | Manage polling interval, notification channels, data deletion. | Save preferences → backend API. |

| Test type | Example scenario | |-----------|------------------| | Unit | Mock API response → verify fetchNewTweets returns correct shape. | | Integration | Spin up a test DB, run the scheduler, ensure no duplicate tweets are stored. | | Load | Simulate 100 concurrent users on the feed; verify latency < 200 ms. | | Rate‑limit | Force a 429 response → ensure back‑off and graceful degradation. | | Security | Run OWASP ZAP scan; check that bearer token never appears in logs or client‑side code. | | Compliance | Verify data‑deletion endpoint removes all rows linked to a given tweet ID within 24 h. |
