I like that you can run pure tests in local or cloud environments without any external dependencies (like containers).It's great to have different versions running at same time with ease so it makes development easier by letting us quickly make changes live as we go along rather than having one big version stuck somewhere which might not be good enough yet! It would really help if some way could exist where multiple people work together but their code does't get merged into master until they've tested every single combination between them using this feature before merging - otherwise there will just always need someone who works all alone doing lots more boring stuff while others are working closely collaborating via pull requests etcetera? This has been solved since then because our team now uses CI/CD pipelines instead (to merge PRs) however when those fail during deployment due solely from network issues e g., internet being down temporarily causing deploy failures.
