Momentic can use traces from past test runs to improve AI consistency and reliability.

How memory works

Natural language phrases can often be interpreted in different ways. For example, does the description “the selected tab” refer to “the currently selected tab”, or does it mean “the tab with the text ‘Selected’”? What if both options exist on the page? In order to eliminate flakiness, it is imperative that AI chooses a single interpretation for each query across different test runs. To achieve this, Momentic stores AI completions from successful test runs and supplies those traces back to the AI agent when generating new completions. By using past runs’ decisions and logical reasoning processes as context, we can ensure Momentic’s AI agents are making consistent decisions.

When memory is used

Memory is used whenever a step uses AI to locate an element or evaluate an assertion. This includes interactive steps like CLICK as well as assertions like AI CHECK and ELEMENT CHECK.

Storage and expiration

Memory is:
  • Securely stored on Momentic Cloud.
  • Isolated per organization and only accessible during authenticated test runs.
  • Automatically expired after 30 days of inactivity.
  • Supported by our locator and assertion agents currently.
Momentic automatically chooses the most relevant traces to keep in memory, preventing memory size from growing indefinitely.

Failed steps and memory

If enabled, memory is updated whenever a step executes and uses AI. Even if the test ultimately fails, Momentic still stores a memory entry for that step. This behavior helps tests fail consistently when there are legitimate errors.

Enabling memory

Memory can always be controlled on a per-test basis through the test’s AI options in the test editor. The default setting for memory can be controlled through the organization-level AI settings on Momentic Cloud, and through the project configuration file when using the CLI.
