Test scenario for Classic Bluetooth (BR/EDR) continuous data streaming
- verify data can be transmitted consistently and reliably over a Bluetooth connection.
Test Case: Continuous Data Streaming over Classic Bluetooth (BR/EDR) Objective: To ensure that a Classic Bluetooth (BR/EDR) connection can handle continuous data streaming effectively without data loss or significant performance degradation.
Test Environment:
- Devices: Two Bluetooth-enabled devices with BR/EDR support (e.g., smartphones, tablets, or specialized Bluetooth test devices).
- Software: Bluetooth communication application or test tool that supports continuous data transfer.
- Configuration: Ensure both devices are paired and connected using Classic Bluetooth (BR/EDR).
Test Steps
1.Setup and Initialization:
- Pair Devices: Pair the two Bluetooth devices if not already paired.
- Establish Connection: Connect the devices using Classic Bluetooth (BR/EDR) in a data transfer mode (e.g., SPP - Serial Port Profile).
2. Test Preparation:
- Select Data Source: Choose or create a data source for streaming (e.g., a file with a known size or a data generator tool).
- Determine Stream Rate: Define the rate at which data will be sent (e.g., 1 MB per minute).
3.Continuous Data Streaming:
- Start Data Transmission: Begin streaming data from the source device to the target device.
- Monitor Data Transfer: Use monitoring tools or software to observe data transmission rates and ensure the data is being sent continuously.
4.Metrics Collection:
- Measure Throughput: Record the data transfer rate (throughput) during the streaming process. Track Latency: Measure the latency of data packets (time taken for a packet to travel from the sender to the receiver).
- Monitor Errors: Check for any data errors, lost packets, or retransmissions.
5.Stress Testing:
- Increase Data Rate: Gradually increase the data transfer rate to test the limits of the Bluetooth connection.
- Vary Environment: Test in different environments to observe how factors like distance and obstacles affect data streaming.
6.Interruption Testing:
- Simulate Interference: Introduce potential sources of interference (e.g., other Bluetooth devices, Wi-Fi networks) and observe the impact on data streaming.
- Disconnection and Reconnection: Temporarily disconnect one device and reconnect to ensure that the streaming resumes correctly.
7.Data Integrity Check:
- Verify Data: After the streaming is complete, verify that the received data matches the sent data without corruption or loss.
- Check File Integrity: If using a file-based approach, compare the original file with the received file for consistency.
Expected Results:
- Consistent Throughput: The data transfer rate should be consistent with the expected rate and should not fall below a specified threshold.
- Minimal Latency: Latency should be within acceptable limits as defined by the application or Bluetooth specification.
- No Data Loss: Data should be transmitted and received without loss or corruption.
- Stable Connection: The connection should remain stable throughout the streaming process, even under stress or interference conditions.
Reporting:
- Document the test results, including throughput, latency, any data loss or corruption, and the impact of environmental factors.
- Include screenshots or logs from monitoring tools if applicable.
In some Agile teams you will have a debriefing/retro in which you can contribute
- Provide recommendations based on test findings, such as improvements needed for better performance or stability.
