test.ai

aid: test-ai
name: test.ai
description: 'test.ai (formerly Appdiff, Inc.) built an AI-powered test-automation platform that used computer vision and
  machine-learning element classification to make Selenium and Appium tests resilient to UI change. It published first-party
  Java, Python, Node.js and Ruby SDKs, a gRPC "Classifier" service that labelled UI elements from screenshots, an Appium classifier
  plugin, and OpenTestData — a free open database of automated test fixture data with its own REST API. The company raised
  over $30M and was sold; its founder has since moved on to other ventures. As of 2026-08-30 test.ai serves no website of
  its own: the domain has no HTTPS listener and every HTTP path redirects off-domain. The artifacts profiled here are the
  contracts and packages the company published while operating, all of which remain publicly retrievable from its own GitHub
  organization and from the npm, PyPI, RubyGems and Maven Central registries.'

  description: REST API behind opentestdata.org, test.ai's free and open database of automated test fixture data. 13 paths
    / 16 operations covering user signup and login, e-mail confirmation, avatars, admin promotion, test and datum create/read/update,
    and a combined search over tests and data. Authenticated with a JWT bearer token. The publicly hosted instance the provider
    documented, api.opentestdata.org, no longer resolves; the contract survives in the company's own repository.

- name: test.ai Classifier
  description: gRPC service that classifies UI element screenshots into semantic labels. A single RPC, ClassifyElements, takes
    a map of element id to PNG bytes plus a label hint, a confidence threshold and a weaker-match flag, and returns a per-element
    label with confidence scores. This is the engine behind the test.ai Appium classifier plugin and the Java, Python, Node.js
    and Ruby classifier clients. The server is run by the consumer, so there is no vendor-hosted base URL — the clients take
    host and port as constructor arguments.
