Overview

Vendored Google Closure Library module providing logging and debugging utilities used by Selenium JavaScript atoms.

Description

goog.debug is a vendored copy of the Google Closure Library module. It provides logging and debugging utilities including error catching, object inspection/exposure, error normalization and enhancement, and stack trace generation. It supports configurable logging enablement and sloppy stack building modes. Selenium uses this as part of its JavaScript atom infrastructure for browser automation commands.

Usage

This module is consumed internally by Selenium's JavaScript atoms build system. It is not imported directly by end users.
