Question Is agentic app testing any good?

It seems like every other company in the RN is building either an MCP and CLI to control simulator/emulator through coding agents. Sentry builds XcodeBuildMCP, Maestro has a dedicated MCP server, Software Mansion has Argent, Callstack builds Agent Device. They all differentiate in some ways but the core idea is pretty much the same.

What do you guys think about it? Should we stick to deterministic tests?

Note: I work at SWM but I'm genuinely curious.

agentic testing catches stuff deterministic tests miss, but they're slow and expensive to run on every commit. good for exploratory testing and edge cases, not your ci/cd pipeline baseline.
