Package Exports

appium-chromium-driver
appium-chromium-driver/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (appium-chromium-driver) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

appium-chromium-driver

This is an Appium driver for Chromium-based browsers (like Chrome).

Why does this project exist?

It is already possible to automate Chromium browsers with Chromedriver. In fact, this Appium driver uses Chromedriver under the hood! It is not any kind of fundamentally new or different technology. The advantages of using this project are:

Automate Chromium browsers using the Appium server you already have, simply by including this Appium driver.
No need to download specific versions of Chromedriver manually. This driver takes care of downloading a version of Chromedriver appropriate for the version of the browser under test.
Take advantage of the ecosystem of Appium plugins and features (e.g., image analysis) not available via Chromedriver on its own.

Installation

It's assumed that you have an Appium server (version 2.x+) installed, and that you have a browser compatible with Chromedriver ready to automate on your system. The recommended installation method is to use the Appium extension CLI to install the driver:

appium driver install chromium

Usage

To start an automation session targeting this driver, construct a set of options/capabilities in any WebDriver client that (minimally) includes the following:

Capability	Value
`platformName`	One of `macOS`, `Linux`, or `Windows` (depending on your system
`browserName`	`chrome`
`appium:automationName`	`Chromium`

Use these capabilities to start a new session. (Refer to the documentation for your WebDriver client for the particular syntax used to start a session in that client).

At this point, all WebDriver commands are proxied directly to Chromedriver. This driver does not implement any additional commands. Refer to the Chromedriver documentation or the WebDriver specification for a list of the available automation commands.

Capabilities

In addition to all of the Chromedriver capabilities (nested underneath goog:chromeOptions), this driver supports the following:

Capability	Description	Default Value
`appium:chromedriverPort`	The port to start Chromedriver on	`9515`
`appium:executable`	The absolute path to a `chromedriver` binary executable. If set, the driver will use that path instead of its own Chromedriver
`appium:executableDir`	A directory within which is found any number of `chromedriver` binaries. If set, the driver will search this directory for Chromedrivers of the appropriate version to use for your browser
`appium:verbose`	Set to `true` to add the `--verbose` flag when starting Chromedriver	`false`
`appium:logPath`	The path to use with the `--log-path` parameter directing Chromedriver to write its log to that path, if set
`appium:disableBuildCheck`	Set to `true` to add the `--disable-build-check` flag when starting Chromedriver	`false`
`appium:autodownloadEnabled`	Set to `false` to disable automatic downloading of Chromedrivers	`true`
`appium:useSystemExecutable`	Set to `true` to use the version of Chromedriver bundled with this driver, rather than attempting to download a new one based on the version of the browser under test	`false`
