FAQ

How does the platform handle the creation of automated tests for users without coding experience?

The platform utilizes a low-code editor where users describe the desired test flow in plain English. The AI interprets these natural language instructions to generate and execute the automated test coverage, significantly reducing the time required for automation compared to traditional methods (verified: 2026-01-30).

What specific features are available to help teams manage and maintain their automated test suites?

Momentic provides several core features including auto-healing, step caching, and failure analysis to ensure test stability. It also supports environment variables, modules, and request mocking to help engineering teams scale their coverage to hundreds of tests quickly (verified: 2026-01-30).

Can this tool be used to verify features that involve non-deterministic outputs from generative AI?

Yes, the tool includes specific Gen AI testing capabilities designed to validate LLM features. It uses intent-based checks that handle non-deterministic outputs, allowing teams to run automated evaluations across numerous prompts simultaneously (verified: 2026-01-30).
