ChromeDriver
An NPM wrapper for Selenium ChromeDriver.
Building and Installing
npm install chromedriver
Or grab the source and
node ./install.js
What this is really doing is just grabbing a particular "blessed" (by
this module) version of ChromeDriver. As new versions are released
and vetted, this module will be updated accordingly.
The package has been set up to fetch and run ChromeDriver for MacOS (darwin),
Linux based platforms (as identified by nodejs), and Windows. If you
spot any platform weirdnesses, let us know or send a patch.
Custom binaries url
To use a mirror of the ChromeDriver binaries use npm config property chromedriver_cdnurl
.
Default is http://chromedriver.storage.googleapis.com
.
npm install chromedriver --chromedriver_cdnurl=http://npm.taobao.org/mirrors/chromedriver
Or add property into your .npmrc
file.
chromedriver_cdnurl=http://npm.taobao.org/mirrors/chromedriver
Another option is to use PATH variable CHROMEDRIVER_CDNURL
.
CHROMEDRIVER_CDNURL=http://npm.taobao.org/mirrors/chromedriver npm install chromedriver
Running
bin/chromedriver [arguments]
And npm will install a link to the binary in node_modules/.bin
as
it is wont to do.
Running with Selenium WebDriver
require('chromedriver');
var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder()
.forBrowser('chrome')
.build();
(Tested for selenium-webdriver version 2.48.2
)
The path will be added to the process automatically, you don't need to configure it.
But you can get it from require('chromedriver').path
if you want it.
Running via node
The package exports a path
string that contains the path to the
chromdriver binary/executable.
Below is an example of using this package via node.
var childProcess = require('child_process');
var chromedriver = require('chromedriver');
var binPath = chromedriver.path;
var childArgs = [
'some argument'
];
childProcess.execFile(binPath, childArgs, function(err, stdout, stderr) {
});
You can also use the start and stop methods:
var chromedriver = require('chromedriver');
args = [
];
chromedriver.start(args);
chromedriver.stop();
Note: if your tests are ran asynchronously, chromedriver.stop() will have to be
executed as a callback at the end of your tests
Versioning
The NPM package version tracks the version of chromedriver that will be installed,
with an additional build number that is used for revisions to the installer.
A Note on chromedriver
Chromedriver is not a library for NodeJS.
This is an NPM wrapper and can be used to conveniently make ChromeDriver available
It is not a Node JS wrapper.
