To test our software effectively, we employ various methods. Our primary approach involves integrating our code into a Raspberry Pi 3 and connecting multiple sensors to it.
In an ideal scenario, we envision attaching the setup to a rocket for multiple test launches. This will help us:
- Identify potential errors
- Assess performance in fast and long-distance environments
However, due to substantial costs, we opt for simpler tests like walking around with the device to ensure successful data collection from all sensors.
Our focus extends to ensuring the software seamlessly interfaces with a database, managing and correctly storing information from sensors, especially under hardware error conditions.
To simulate challenging scenarios, we:
- Intentionally remove sensors during testing
- Check for potential disconnects, particularly relevant in a rocket environment
Since testing on a physical Raspberry Pi demands significant time, we use a virtual environment that mirrors the Raspberry Pi's behavior. This is crucial for running sensor libraries exclusive to the Raspberry Pi.
Our development process involves:
- Using a server
- Collaborative work on GitHub
A notable challenge is sensor testing in the virtual environment due to the lack of actual sensor data. We counter this by ensuring software functionality based on documentation, followed by live testing sessions.
For delivery, clients will receive the source code, deployable on multiple Raspberry Pis. Upon initiation, the software:
- Automatically identifies connected sensors
- Begins data collection
- Organizes information into a table for post-testing analysis
