There should not be long strings of commits that focus on features. Continuous development means continuously looking after developers, too: intersperse commits that remove code, increase documentation, update versions of dependencies, fix ancient bugs or whatever else eases maintenance. Test suites should not just be thrown together, where every test is a "diff" of a giant log file! You do NOT want to be constantly fixing “tests” that “fail” due to trivial differences. Ensure that your code can completely expose all relevant state for one feature so that you can write precise checks and ignore any other output. There should be no compile-time options (like #ifdef) that are not automatically built before every commit. Developers change things, and they have to know exactly what can break by doing so (especially with languages like C++, where a tiny change can cause true chaos). Put another way, don’t set yourself up to discover problems weeks from now at the worst possible moment; build defensive code and infrastructure.
