" summary

Compares testing needs of web services versus safety- and mission-critical systems used on spacecraft, and presents a rubric for choosing verification approaches based on software and environment attributes. Shows a real-world example using pytest (fixtures, hook system) plus Python features (generators, context managers, threading) to test Varda Space Industries' spacecraft software, including tools for real-time telemetry testing and rich test reporting.
