Modes
Each workflow runs in one of two modes, chosen at creation time: Deterministic - Lark’s AI writes a test script based on your description. The script runs the same steps on each invocation. If your product changes, Lark repairs the script to match. Best for repeatable regression tests. AI-driven - Lark’s AI performs the test from scratch on each run, deciding how to reach the goal you described. No stored script. Best for exploratory tests and complex flows where the exact path may vary.Workflow statuses
A workflow moves through these statuses as Lark generates, runs, and maintains it:Summarization
When a deterministic workflow’s execution fails, Lark runs a summarization step before deciding what to do next. Summarization classifies the failure as one of:
This split keeps repairs targeted (only when the script is the problem) and stops alert noise from script drift. AI-driven workflows skip summarization. They have no stored script to be at fault.
