Browser Actuator

//components/browser_actuator is a layered Chromium component that provides the foundational architecture for service-oriented browser actuation.

Component Organization

This is a layered component designed for cross-platform reuse, and it also cleanly separates public APIs and internal implementations.

public/: Public API headers and feature flags defining the service interface (BrowserActuatorService), allowing embedders (e.g., //chrome, //ios) to consume the service without depending on internal implementation details.
internal/: Internal service implementations, transport routing logic, session state machines, and protocol handlers.
test_support/: Fakes, mocks, and test utilities for unit and browser integration testing.

When building and testing, you can use the following commands:

zsh

autoninja -C out/Default components/browser_actuator

To run unit tests for this component, use autotest.py:

zsh

tools/autotest.py -C out/Default components/browser_actuator
