momentic-test

Momentic is an end-to-end testing framework that uses AI agents to automate browser interactions via Playwright and CDP. It manages tests and modules as serialized YAML files, supporting both v1 (MCP-only) and v2 (direct-edit) formats.

Review the source first

Review the source first: our audit of momentic-test's source files found 1 shell command, 2 external URLs, file reads and writes (high risk). Every command and URL listed appears verbatim in the skill's source. The tool reads and writes local test files (*.test.yaml, *.module.yaml) and configuration files. It executes shell commands for linting and interacts with browser sessions which can perform destructive actions like form submissions or deletions.

# Momentic background

## Execution model

Momentic is an end-to-end testing framework. Tests are ordered lists of
structured steps executed with Playwright and CDP.

- Interactive steps such as clicks and types use AI to resolve natural-language
  targets into concrete browser actions.
- Assertion steps can use multimodal models to evaluate page state.
- Goal-based AI actions can perform broader tasks such as "checkout with credit card".

## Cache and memory

Momentic caches resolved step metadata such as selectors, XPaths, visible text,
and coordinates so most runs avoid repeated AI calls. T...

Frequently asked questions

How do I choose between v1 and v2 formats?

v2 files contain a fileType field and support direct YAML editing. v1 files lack this field and must be modified exclusively through the momentic_test_splice_steps tool.

How does Momentic handle test speed?

It caches resolved step metadata like selectors and coordinates. You can bypass this with --disable-cache or force fresh behavior by changing step descriptions.

Can I use JavaScript in my tests?

Yes. JavaScript steps can run in NODE or BROWSER contexts. NODE context provides access to libraries like axios, faker, and pg, while BROWSER context provides access to window and document.

What is the recommended way to handle risky actions like deletions?

Avoid repeated previews. Preview the setup steps, splice the checkpoint before the risky action, and execute the saved step only once.
