A new standard for "passing."
The tests pass.
But do you know what they're testing?
A prompt changes. A component gets restyled. An agent edits a test to make it pass.
The suite stays green the whole time, because green was never the same as correct.
It just used to be close enough that nobody checked the difference.
LitmusLab is the definition of "good" your tests answer to,
kept outside the code that keeps changing around them.
Your users follow workflows.
Your tests should too.
Your users ask follow-up questions. They change direction. They click through screens you didn't script for.
LitmusLab tests against the real situational data your workflows operate on—an API response or a rendered screen—and judges the result against what you actually intended, not just whether it ran. Build scenarios, define what success looks like, and run every release against them, even as your contexts grow.
Test what an endpoint returns. Chain requests, extract values, evaluate the response with deterministic checks and plain-language judgment, side by side.
Test what a screen shows. Walk a real workflow in a browser (no coding necessary), capture what happened, and evaluate it against what you meant to build.
Over time, it becomes a system. Add a new scenario—a new customer persona, a new user state, a new use case—and your existing tests automatically cover it. Every release ships with more confidence than the last.
Built for the whole team, not just developers
