I think asking here is a good idea but you should also try this question on the LLMs like perplexity, chatGPT , etc. This question might be too high level and not contain enough context, but you can ask the model how to focus your question to specific aspects of your business. The models can outline the tradeoffs you can expect once you pick a tech stack and a team. The models can also suggest how things might go wrong and what you should watch out for. Try and get the LLMs to design your test suite.

Remember: There's no one-size-fits-all answer. The best approach depends on your specific circumstances, goals, and resources.
