The original test used an elapsed time of two seconds against a three-second timeout, so it exercised the healthy path despite its test name, and it did not check any state changes.

CubeSat Fault Detection and Recovery Unit Test Repair Dataset
This dataset contains small-satellite flight software functions for fault detection, fault-state updates, and recovery, along with flawed and repaired unit tests for those functions. Examples cover common issues such as missing assertions, incorrect test inputs, and mismatched mock dependencies. The training objective is to generate repaired tests that verify fault-handling branches and expected state changes, supporting code SFT, spacecraft fault-handling test generation, and unit test repair.
