IE specific functionality

These are capabilities and features specific to Microsoft Internet Explorer browsers.

As of June 2022, Selenium officially no longer supports standalone Internet Explorer. The Internet Explorer driver still supports running Microsoft Edge in “IE Compatibility Mode.”

Special considerations

The IE Driver is the only driver maintained by the Selenium Project directly. While binaries for both the 32-bit and 64-bit versions of Internet Explorer are available, there are some known limitations with the 64-bit driver. As such it is recommended to use the 32-bit driver.

Additional information about using Internet Explorer can be found on the IE Driver Server page

Options

Starting a Microsoft Edge browser in Internet Explorer Compatibility mode with basic defined options looks like this:

        InternetExplorerOptions options = new InternetExplorerOptions();
        options.attachToEdgeChrome();
        options.withEdgeExecutablePath(getEdgeLocation());
        driver = new InternetExplorerDriver(options);

As of Internet Explorer Driver v4.5.0:

  • If IE is not present on the system (default in Windows 11), you do not need to use the two parameters above. IE Driver will use Edge and will automatically locate it.
  • If IE and Edge are both present on the system, you only need to set attaching to Edge, IE Driver will automatically locate Edge on your system.

So, if IE is not on the system, you only need:

Here are a few common use cases with different capabilities:

fileUploadDialogTimeout

In some environments, Internet Explorer may timeout when opening the File Upload dialog. IEDriver has a default timeout of 1000ms, but you can increase the timeout using the fileUploadDialogTimeout capability.

InternetExplorerOptions options = new InternetExplorerOptions();
options.waitForUploadDialogUpTo(Duration.ofSeconds(2));
WebDriver driver = new RemoteWebDriver(options);
  
    options = webdriver.IeOptions()

ensureCleanSession

When set to true, this capability clears the Cache, Browser History and Cookies for all running instances of InternetExplorer including those started manually or by the driver. By default, it is set to false.

Using this capability will cause performance drop while launching the browser, as the driver will wait until the cache gets cleared before launching the IE browser.

This capability accepts a Boolean value as parameter.

ignoreZoomSetting

InternetExplorer driver expects the browser zoom level to be 100%, else the driver will throw an exception. This default behaviour can be disabled by setting the ignoreZoomSetting to true.

This capability accepts a Boolean value as parameter.

ignoreProtectedModeSettings

Whether to skip the Protected Mode check while launching a new IE session.

If not set and Protected Mode settings are not same for all zones, an exception will be thrown by the driver.

If capability is set to true, tests may become flaky, unresponsive, or browsers may hang. However, this is still by far a second-best choice, and the first choice should always be to actually set the Protected Mode settings of each zone manually. If a user is using this property, only a “best effort” at support will be given.

This capability accepts a Boolean value as parameter.

Command-Line Options

Internet Explorer includes several command-line options that enable you to troubleshoot and configure the browser.

The following describes few supported command-line options

  • -private : Used to start IE in private browsing mode. This works for IE 8 and later versions.

  • -k : Starts Internet Explorer in kiosk mode. The browser opens in a maximized window that does not display the address bar, the navigation buttons, or the status bar.

  • -extoff : Starts IE in no add-on mode. This option specifically used to troubleshoot problems with browser add-ons. Works in IE 7 and later versions.

Note: forceCreateProcessApi should to enabled in-order for command line arguments to work.

Service

Service settings common to all browsers are described on the Service page.

Log output

Getting driver logs can be helpful for debugging various issues. The Service class lets you direct where the logs will go. Logging output is ignored unless the user directs it somewhere.

File output
