Test Driven in the AI Agent Era
Digital Democracy 2030 Slack

I let my own service with E2E testing tinker around to use my Devin's soon-to-expire credits, but it was amazing to see him accomplish things that people don't want to do, like updating Firebase and React (small scale).
I have a growing feeling that it is still important to maintain tests so that I can easily throw tasks to AI, and I want to start with small tests and put them into CI.
I think it would be better to position the test not as a way to reduce speed and improve quality, but as a way to quickly notice mistakes when speed is increased, and make it a rule that the test results can be merged without checking them.
So, it's like there are high-quality tests maintained by humans and AI-generated tests based on them.
I wonder if it would be possible to notify Slack which tests are failing often or when a high quality test fails.

Using AI generated tests to make Go/NoGo decisions is a totally different paradigm from conventional testing, maximizing return on investment without aiming for all green.
takahiroanno Evaluating high quality human-written tests, AI-generated tests, LLM E2E test signals by Browser-use, etc., while mixing them. Evaluating mixed signals, without aiming for All Green (LLM E2E test is probabilistic to begin with), there could be a more risk-taking and cost-effective flow to make a Go/NoGo decision...?

Probabilistic test
nishio I think there is going to be a shift from the traditional concept of test-driven AI agents in the age of AI agents, where all tests are expected to succeed, to ensemble a bunch of probabilistic discriminators to make them stronger. I think there is going to be a shift equivalent to the paradigm shift from rule-based to machine learning with if statements.
