Working status

• Test purpose: Ensure that the robot vacuum can properly report each working status.
• Scenario: Check the real-time status of the robot vacuum on the app.
• Test method: Check whether the status on the app is correct when the robot vacuum is in each working status.
• Pass standard: The current working status of the robot vacuum can be displayed on the app in real time.

Sweeping time and area

• Test purpose: During sweeping, ensure that the robot vacuum can properly report the sweeping time and area.
• Scenario: Check the sweeping time and area on the app.
• Test method: Check the sweeping time and area displayed on the app when the robot vacuum is working.
• Pass standard: The sweeping time and area data on the app are basically consistent with the actual situation.

Battery level

• Test purpose: Ensure that the battery level of the robot vacuum is reported properly.
• Scenario: The remaining battery level of the robot vacuum can be displayed on the app.
• Test method: When the robot vacuum is working or charging, check whether the battery level is displayed correctly on the app and whether the battery level properly increases or decreases.
• Pass standard: The battery level displayed on the app remains the same as the battery level of the robot vacuum. During the sweeping and charging process, the battery level evenly decreases or increases.
• Possible problems: After the robot vacuum leaves the charging station and starts to sweep, it might consume too much power.

Map

• Test purpose: Ensure that the map function on the app works as expected.
• Scenario: The app can display the sweeping map and the current location in real time. The map supports zooming, and panning up, down, left, and right.
• Test method: Check the map display on the app in each sweeping mode.
• Pass standard: The route is complete and continuous, without interruption, and is roughly the same as the actual operation of the robot vacuum. The current location is displayed accurately.
• Possible problems: The map is not updated in real time, and the map display is inconsistent with the actual operation.

Sweeping history

• Test purpose: Ensure that the sweeping history data is correct and complete.
• Scenario: Users can view the sweeping results and history on the app.
• Test method: After sweeping is completed each time, check whether the information in the sweeping history on the app is correct.
• Pass standard: The data in the sweeping history is correct and complete, without repetition.
• Possible problems: The sweeping history is not reported, the displayed map is incorrect, and the history data is not cleared after the robot vacuum is restored to factory default settings.

Consumable management

• Test purpose: Ensure that the app can display the remaining amount of consumables properly.
• Scenario: Remind users to replace consumables in time.
• Test method: Check the accuracy of reporting the remaining amount before and after consumables are replaced.
• Pass standard: The remaining amount of consumables is consistent with the actual amount.
• Possible problems: Users reset the remaining amount of consumables on the app, but the value is not restored to the default value.

Manual control

• Test purpose: Ensure that the manual control function of the robot vacuum works as expected.
• Scenario: On the app, perform remote control of the robot vacuum.
• Test method: Use the manual control function on the app, tap the forward, backward, left, and right buttons to check whether the robot vacuum is running as expected.
• Pass standard: The robot vacuum properly moves forward, backward, left, and right. The robot vacuum will move continuously after a user holds down the direction button on the app, and stop immediately after the user releases the button.

Location

• Test purpose: Ensure the location function of the robot vacuum works properly.
• Scenario: Help users quickly locate the robot vacuum.
• Test method: In each status, tap the location button on the app.
• Pass standard: The robot vacuum can send a prompt tone in time.

Sleep mode

• Test purpose: Ensure that the sleep mode is functional.
