No, it’s shitty because it’s complicated, looks correct, but actually filled with errors and hallucinations. Including libraries that may not exist, and that leaves code open to injection attacks (where people make fake libraries/dependies based on commonly hallucinated code, then package them with genuine FOSS software which is now playing cover for malware/viruses).
Maybe big companies and projects with lots of people do white tests, but indie devs don’t. FOSS is not the well organized machine you may have it confused for.
