At this point I only see value in manual QA testing for front-end apps. It's now possible to test pretty much anything via automation, although front-end testing is still harder than most and there are some intangible UX issues that can only be experienced by human users. But for testing APIs? It is normally possible to cover 100% of what is needed via a combination of unit tests and integration tests. This is especially true now that tooling exists that can bring up ephemeral test environments with dependencies such as databases etc.
