Testing 1, 2, 3 (`Simulator`)

Building better testing tools

With new developments, testing by hand is no longer practical!

As a result, I've developed a Simulator which will do all the major testing from now on.

This post is just a show-and-tell because it's a fun tool.

Comprehensive Simulator / Test Harness

Testing now makes use of new Simulator capabilities, such as:

Simulating any scenario, directly feeding encoded data into the live Dashboard
- No need to transmit to test
27,000+ automated tests, across comprehensive input values, midpoints, etc
- Test every message type (extensible to new)
- Test pairs of messages (TT+GT, RT1+BT, etc)

Major Features

Simulation of "real" data by Simulator, then sent to Jetpack via JSON link
- Encoding performed ON Jetpack using Jetpack encoder/decoder
- Encoding performed Simulator using Dashboard encoder/decoder
- Resulting values compared by Simulator and differences flagged
Drawable GPS path on map
- With comparative view of grid4/grid6 snap-to path
Drawable altitude/speed/temperature/voltage values
Bulk Comprehensive test scenarios auto-generated
Window construction (any messages, any field values, in any slots)
Fingerprinting scenarios
- Multiple sending profiles to operate simultaneously
  - Any band/channel
- Multiple receiving station profiles to operate simultaneously
  - Any band/freq-offset
Solar angle conditions (choose date/time of simulated period)

Other Cool Stuff

2.6 Mbps data throughput between Simulator and Jetpack traffic via JSON link
- That's 325,000 bytes/sec for write, and another 325,000 bytes/sec for read
- Reliable high-bandwidth link supports high-volume low-latency testing

More work to be done to move this set of work ahead but now much easier to test and re-test as changes get made to see what works.
