🧪 Test Case: Secure Background Scanning Verification (v1.0.3)

🎯 Goal

Verify that background scanning operates securely — the app records WiFi/Bluetooth scans with GPS data in the database while in the background, and the passphrase is only cached during active scanning.

---

✅ Test Checklist

• Start a WiFi/Bluetooth scan in the app.
• Send the app to the background (press Home or switch to another app).
• Move to different locations for several minutes to generate GPS data.
• Return to the app.
• Stop the scan.
• Check the database for new scan entries recorded during the background period.
• Confirm GPS coordinates and timestamps are present in the new entries.
• After stopping the scan, verify that the passphrase is cleared from memory.
• Confirm the unlock dialog appears when reopening the app after stopping the scan.
• Ensure app content is hidden by a black overlay until the passphrase is re-entered.

---

🧾 Expected Results

• WiFi/Bluetooth scans and GPS data are successfully recorded while the app runs in the background (if scanning is active).
• Passphrase remains cached only during active scanning.
• Passphrase is cleared and re-entry required once scanning stops or the app is closed.
• App content remains hidden behind the black overlay until successful unlock.

🧭 Notes

• Test on multiple devices and Android versions if possible.
• Report any cases where scans are missing, GPS data is incomplete, or the security overlay/passphrase logic fails.
