Edge固有の機能
Microsoft EdgeはChromiumで実装されており、サポートされている最も古いバージョンはv79です。 Chromeと同様に、edgedriverのメジャー バージョン番号は、Edgeブラウザのメジャーバージョンと一致する必要があります。
Chromeページ にあるすべての機能とオプションは、Edgeでも機能します。
オプション
Capabilities common to all browsers are described on the Options page.
Capabilities unique to Chromium are documented at Google’s page for Capabilities & ChromeOptions
基本的な定義済みオプションを使用して Edgeセッションを開始すると、次のようになります。
driver = new EdgeDriver(options);
} options = webdriver.EdgeOptions()
driver = webdriver.Edge(options=options) var options = new EdgeOptions();
driver = new EdgeDriver(options); options = Selenium::WebDriver::Options.edge
@driver = Selenium::WebDriver.for :edge, options: options driver = await env.builder()
.setEdgeOptions(options)
.build();
});
引数
The args parameter is for a list of command line switches to be used when starting the browser.
There are two excellent resources for investigating these arguments:
一般的に使用される引数には、--start-maximized および --headless=new が含まれます。 and --user-data-dir=...
オプションに引数を追加します。
options.add_argument("--start-maximized") options.AddArgument("--start-maximized"); options.args << '--start-maximized' .setEdgeOptions(options.addArguments('--headless=new'))Start browser in a specified location
The binary parameter takes the path of an alternate location of browser to use. With this parameter you can
use chromedriver to drive various Chromium based browsers.
Add a browser location to options:
options.binary_location = edge_bin options.BinaryLocation = GetEdgeLocation(); options.binary = edge_locationAdd extensions
The extensions parameter accepts crx files. As for unpacked directories,
please use the load-extension argument instead, as mentioned in
this post.
Add an extension to options:
options.add_extension(extension_file_path) options.AddExtension(extensionFilePath); options.add_extension(extension_file_path)Keeping browser open
Setting the detach parameter to true will keep the browser open after the process has ended,
so long as the quit command is not sent to the driver.
Note: This is already the default behavior in Java.
options.add_experimental_option("detach", True)Note: This is already the default behavior in .NET.
options.detach = trueExcluding arguments
MSEdgedriver has several default arguments it uses to start the browser.
If you do not want those arguments added, pass them into excludeSwitches.
A common example is to turn the popup blocker back on. A full list of default arguments
can be parsed from the
Chromium Source Code
Set excluded arguments on options:
options.add_experimental_option('excludeSwitches', ['disable-popup-blocking']) options.AddExcludedArgument("disable-popup-blocking"); options.exclude_switches << 'disable-popup-blocking'Service
Examples for creating a default Service object, and for setting driver location and port can be found on the Driver Service page.
Log output
Getting driver logs can be helpful for debugging issues. The Service class lets you direct where the logs will go. Logging output is ignored unless the user directs it somewhere.
File output
To change the logging output to save to a specific file:
Note: Java also allows setting file output by System Property:
Property key: EdgeDriverService.EDGE_DRIVER_LOG_PROPERTY
Property value: String representing path to log file
service = webdriver.EdgeService(log_output=log_path) service.LogPath = GetLogLocation();Console output
To change the logging output to display in the console as STDOUT:
Note: Java also allows setting console output by System Property;
Property key: EdgeDriverService.EDGE_DRIVER_LOG_PROPERTY
Property value: DriverService.LOG_STDOUT or DriverService.LOG_STDERR
$stdout and $stderr are both valid values
service.log = $stdoutLog level
There are 6 available log levels: ALL, DEBUG, INFO, WARNING, SEVERE, and OFF.
Note that --verbose is equivalent to --log-level=ALL and --silent is equivalent to --log-level=OFF,
so this example is just setting the log level generically:
new EdgeDriverService.Builder().withLoglevel(ChromiumDriverLogLevel.DEBUG).build();
Note: Java also allows setting log level by System Property:
Property key: EdgeDriverService.EDGE_DRIVER_LOG_LEVEL_PROPERTY
Property value: String representation of ChromiumDriverLogLevel enum
service = webdriver.EdgeService(service_args=['--log-level=DEBUG'], log_output=log_path)Log file features
There are 2 features that are only available when logging to a file:
- append log
- readable timestamps
To use them, you need to also explicitly specify the log path and log level. The log output will be managed by the driver, not the process, so minor differences may be seen.
new EdgeDriverService.Builder().withAppendLog(true).withReadableTimestamp(true).build();
Note: Java also allows toggling these features by System Property:
Property keys: EdgeDriverService.EDGE_DRIVER_APPEND_LOG_PROPERTY and EdgeDriverService.EDGE_DRIVER_READABLE_TIMESTAMP
Property value: "true" or "false"
service = webdriver.EdgeService(service_args=['--append-log', '--readable-timestamp'], log_output=log_path) service.args << '--append-log'
service.args << '--readable-timestamp'Disabling build check
Edge browser and msedgedriver versions should match, and if they don’t the driver will error. If you disable the build check, you can force the driver to be used with any version of Edge. Note that this is an unsupported feature, and bugs will not be investigated.
new EdgeDriverService.Builder().withBuildCheckDisabled(true).build();
Note: Java also allows disabling build checks by System Property:
Property key: EdgeDriverService.EDGE_DRIVER_DISABLE_BUILD_CHECK
Property value: "true" or "false"
service = webdriver.EdgeService(service_args=['--disable-build-check'], log_output=log_path) service.DisableBuildCheck = true;Internet Explorer Compatibility モード
Microsoft Edge は、Internet Explorer ドライバークラスを Microsoft Edgeと組み合わせて使用する “Internet Explorer 互換モード"で動かすことができます。 詳細については、Internet Explorerページを参照してください。
Special Features
Some browsers have implemented additional features that are unique to them.
Casting
You can drive Chrome Cast devices with Edge, including sharing tabs
Network conditions
You can simulate various network conditions.
Logs
Permissions
DevTools
