/**
|
|
* @fileoverview Defines a {@linkplain Driver WebDriver} client for the
|
|
* Opera web browser (v26+). Before using this module, you must download the
|
|
* latest OperaDriver
|
|
* [release](https://github.com/operasoftware/operachromiumdriver/releases) and
|
|
* ensure it can be found on your system
|
|
* [PATH](http://en.wikipedia.org/wiki/PATH_%28variable%29).
|
|
*
|
|
* There are three primary classes exported by this module:
|
|
*
|
|
* 1. {@linkplain ServiceBuilder}: configures the
|
|
* {@link selenium-webdriver/remote.DriverService remote.DriverService}
|
|
* that manages the
|
|
* [OperaDriver](https://github.com/operasoftware/operachromiumdriver)
|
|
* child process.
|
|
*
|
|
* 2. {@linkplain Options}: defines configuration options for each new Opera
|
|
* session, such as which {@linkplain Options#setProxy proxy} to use,
|
|
* what {@linkplain Options#addExtensions extensions} to install, or
|
|
* what {@linkplain Options#addArguments command-line switches} to use when
|
|
* starting the browser.
|
|
*
|
|
* 3. {@linkplain Driver}: the WebDriver client; each new instance will control
|
|
* a unique browser session with a clean user profile (unless otherwise
|
|
* configured through the {@link Options} class).
|
|
*
|
|
* By default, every Opera session will use a single driver service, which is
|
|
* started the first time a {@link Driver} instance is created and terminated
|
|
* when this process exits. The default service will inherit its environment
|
|
* from the current process and direct all output to /dev/null. You may obtain
|
|
* a handle to this default service using
|
|
* {@link #getDefaultService getDefaultService()} and change its configuration
|
|
* with {@link #setDefaultService setDefaultService()}.
|
|
*
|
|
* You may also create a {@link Driver} with its own driver service. This is
|
|
* useful if you need to capture the server's log output for a specific session:
|
|
*
|
|
* var opera = require('selenium-webdriver/opera');
|
|
*
|
|
* var service = new opera.ServiceBuilder()
|
|
* .loggingTo('/my/log/file.txt')
|
|
* .enableVerboseLogging()
|
|
* .build();
|
|
*
|
|
* var options = new opera.Options();
|
|
* // configure browser options ...
|
|
*
|
|
* var driver = new opera.Driver(options, service);
|
|
*
|
|
* Users should only instantiate the {@link Driver} class directly when they
|
|
* need a custom driver service configuration (as shown above). For normal
|
|
* operation, users should start Opera using the
|
|
* {@link selenium-webdriver.Builder}.
