momentic.config.yaml lives in your project root and defines a project. One
file covers both web and mobile.
Paths and globs may be relative to the file’s location or absolute.
Configuration sources
Momentic resolves configuration from these sources, highest precedence first:- CLI flags (e.g.
--local-avd-id,--local-apk-path) - Environment variables, including
MOMENTIC_API_KEYand any variable interpolated intomomentic.config.yaml momentic.config.yaml(this file). Includes theai.classificationtoggle for failure classification.- Organization AI settings. Failure categories and auto-heal behavior are configured in the Momentic dashboard and applied when the CLI is authenticated. These remain dashboard-managed and cannot be set in this file.
- CLI defaults
Example
momentic.config.yaml
Reference
Global options
Project name, file globs, retries, parallelism, video recording, Git branch
settings.
Environments
environments[]: name, base URL, env variables, per-env proxy.Environment variables
How Momentic resolves variables at runtime and the reserved variables
available in every test.
Browser
browser.*: defaults for browser type, timezone, timeouts, locator
behavior, AI context filtering.AI
ai.*: per-agent versions, memory, and failure recovery.Mobile
emulator.*: region and runtime options for remote-hosted mobile emulators.Advanced
advanced.*: Faker seed, per-environment cache isolation.Workspaces
Group multiple projects under one repo.
Test file globs
Glob syntax for
include / exclude.Global options
string
Project name, displayed in reports and the dashboard.
momentic.config.yaml
string[]
Globs for test and module files to include. Momentic picks up matching files
automatically when you start the local editor or run tests.
momentic.config.yaml
string[]
Globs for files to exclude. Momentic always excludes
node_modules, .git,
and .venv.momentic.config.yaml
number
Default number of retries per test on failure. A per-test
retries value
overrides this. Default: 1.momentic.config.yaml
number | "auto"
Number of tests to run in parallel. Default for
momentic run: 1.For momentic run, "auto" sizes workers from the host’s CPU cores. When the
project’s browser.remoteBrowser flag is enabled, workers scale to
cores * 4 - 2 (remote browsers are IO-bound); otherwise workers cap at cores
(local browsers are CPU-bound).For mobile projects (momentic-mobile), pass AUTO (CLI flag only, not in
momentic.config.yaml) to run as many tests in parallel as the current shard
contains. Combine with --shard-index / --shard-count so each shard saturates
its capacity.In momentic.config.yaml, only the lowercase form auto is valid.momentic.config.yaml
boolean | "on-fail"
Record video for test runs. Default:
on-fail.true: record every run.false: never record.on-fail: record every run but keep video only for failures.
ffmpeg, which is installed automatically by
momentic install-browsers; mobile recording does not.momentic.config.yaml
string
Directory for Visual diff golden files.
momentic.config.yaml
string
Directory for local run artifacts and result archives. Defaults to
./test-results. The --output-dir run flag overrides this setting.momentic.config.yaml
string
Default directory for reporter output.
momentic.config.yaml
object
Configuration for network reporters. Currently supports
newrelic; see
Push run results to New Relic.momentic.config.yaml
string
Main branch of the repo. When running tests on a new branch, Momentic seeds
cache entries from the nearest commit on this branch. In non-CI
environments, the main branch is also excluded from cache saving. See
cache saving eligibility.
momentic.config.yaml
string[]
Branches considered ineligible for cache saving in non-CI environments.
Prevents accidental cache overwriting on shared branches. See
cache saving eligibility.
momentic.config.yaml
string
Relative path from the project root to use as the Repository root in the
local editor. Display-only. Does not affect test execution or file
resolution.
