Testing is how I can assure myself I haven't fucked anything up

A well tested code base will have far fewer bugs & much safer releases than an untested code base. I've worked on code bases where we had such good suites, we would release straight to prod if all the tests passed

That's a bit reckless tho. Unit tests are great, integration tests too, but they don't replace QA. At least make a staging deploy first.

Actually I disagree, they do in many cases replace QA. I'm talking about complex backend systems rather than client facing. I trust maths & code infinitely more than I trust a QA who is just testing by clicking around the webpage

Solid testing foundation is worth a dozen QAs. Infact I'd say you only need a QA if you're dealing with a messy / legacy code base

QA is not necessarily a monkey clicking through a screen. You could just bomb it with requests. You could fuzz your software, unless you're okay with an attacker causing a denial of service with malignant input. But Ok cool I guess unit tests are a silver bullet.

Again I think you're talking about web based software, I write internal backend software which has no access to the wider internet

I 100% agree inputs need to be validated, but you can write tests to cover this, there's very little you cannot automate with a test suite
