Define InternetExplorerOptions with additional properties that point to the Microsoft Edge browser.

Start an instance of InternetExplorerDriver and pass it InternetExplorerOptions . IEDriver launches Microsoft Edge and then loads your web content in IE mode.

The next section shows the complete sample, and then the subsequent sections focus on each of the main steps that are listed above.

The complete sample

The following sample launches Microsoft Edge in IE mode, navigates to bing.com , and then searches for "WebDriver".

ie_options = webdriver.IeOptions()
ie_options.attach_to_edge_chrome = True
ie_options.edge_executable_path = "C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe"
driver = webdriver.Ie(options=ie_options)
driver.get("http://www.bing.com")
elem = driver.find_element(By.ID, 'sb_form_q')
elem.send_keys('WebDriver' + Keys.RETURN)
driver.quit()

  ieOptions.setEdgePath('C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe');
  let driver = await new Builder().
                         forBrowser('ie').
                         setIeOptions(ieOptions).
                         build();
  try {
    await driver.get('http://www.bing.com');
    let elem = await driver.findElement(By.id('sb_form_q'));
    await elem.sendKeys('WebDriver', Key.RETURN);
    await driver.wait(until.titleIs('WebDriver - Bing'), 1000);
  } finally {
    await driver.quit();
})();
The following sections explain the steps in this sample in more detail.
Define InternetExplorerOptions with additional properties for Microsoft Edge
Define InternetExplorerOptions with additional properties that point to the Microsoft Edge browser.
Python
JavaScript
Define a new variable, ieOptions, by calling InternetExplorerOptions().
Set ieOptions.AttachToEdgeChrome property to true, and ieOptions.EdgeExecutablePath to the path of the Microsoft Edge executable.
var ieOptions = new InternetExplorerOptions();
ieOptions.AttachToEdgeChrome = true;
//change the path accordingly
ieOptions.EdgeExecutablePath = "C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe";
Define a new variable, ie_options, by calling webdriver.IeOptions().
Set the ie_options.attach_to_edge_chrome property to True, and ie_options.edge_executable_path to the path of the Microsoft Edge executable.
ie_options = webdriver.IeOptions()
ie_options.attach_to_edge_chrome = True
ie_options.edge_executable_path = "C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe"
Define a new variable ieOptions of type InternetExplorerOptions, by calling new InternetExplorerOptions().
Call ieOptions.attachToEdgeChrome() and ieOptions.withEdgeExecutablePath() with the path of the Microsoft Edge executable.
InternetExplorerOptions ieOptions = new InternetExplorerOptions();
ieOptions.attachToEdgeChrome();
ieOptions.withEdgeExecutablePath("C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe");
Define a new variable, ieOptions, by calling Options().
Call ieOptions.setEdgeChromium() with value true and ieOptions.setEdgePath() with the path of the Microsoft Edge executable.
let ieOptions = new Options();
ieOptions.setEdgeChromium(true);
ieOptions.setEdgePath('C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe');
Start InternetExplorerDriver and pass it the previously defined ieOptions.  IEDriver launches Microsoft Edge in IE mode.  All page navigation and subsequent interactions occur in IE mode.
var driver = new InternetExplorerDriver(ieOptions);
Start IEDriver by calling webdriver.Ie and passing it the previously defined ie_options.  IEDriver launches Microsoft Edge in IE mode.  All page navigation and subsequent interactions occur in IE mode.
driver = webdriver.Ie(options=ie_options)
Start IEDriver by calling new InternetExplorerDriver() and passing it the previously defined ieOptions.  IEDriver launches Microsoft Edge in IE mode.  All page navigation and subsequent interactions occur in IE mode.
WebDriver driver = new InternetExplorerDriver(ieOptions);
Start IEDriver by calling Builder.forBrowser('ie') and setIeoptions(ieOptions).  IEDriver launches Microsoft Edge in IE mode.  All page navigation and subsequent interactions occur in IE mode.
let driver = await new Builder().
                       forBrowser('ie').
                       setIeOptions(ieOptions).
                       build();
Known limitations
This section covers known scenarios that previously worked with IEDriver and the IE11 desktop application but require workarounds when using IEDriver with Microsoft Edge in IE mode.
Opening new windows
If your test code creates a new browser window using one of the following methods, you may need to add a short wait operation afterwards to ensure that IEDriver has detected the new window:
Opening a new window by calling window.open from <script> in the page.
Opening a new window by using the WebDriver New Window command.
To ensure the new window has been created successfully and IEDriver has detected it, you must continuously check the result of the Get Window Handles command until it contains a handle to the new window.
The following sample demonstrates a possible way to wait for new window handles to be detected when opening new windows.
Python
JavaScript
After the Click method is called on a button that opens a new window, the test code must wait until driver.WindowHandles contains the new window handle.
var initialHandleCount = driver.WindowHandles.Count;
driver.FindElement(By.Id("<Id of the button that will open a new window>")).Click();
var newHandles = driver.WindowHandles;
while (newHandles.Count == initialHandleCount)
    newHandles = driver.WindowHandles;
After the click method is called on a button that opens a new window, the test code must wait until driver.window_handles contains the new window handle.
initial_handle_count = len(driver.window_handles)
driver.find_element(By.ID, "<Id of the button that will open a new window>").click()
new_handles = driver.window_handles
while len(new_handles) == initial_handle_count:
    new_handles = driver.window_handles
After the click method is called on a button that opens a new window, the test code must wait until driver.getWindowHandles() contains the new window handle.
int initialHandleCount = driver.getWindowHandles().size();
driver.findElement(By.id("<Id of the button that will open a new window>")).click();        
Set<String> newHandles = driver.getWindowHandles();
while (newHandles.size() == initialHandleCount) {
    newHandles = driver.getWindowHandles();
After the click method is called on a button that opens a new window, IEDriver must wait with await driver.getAllWindowHandles().
const initialHandleCount = (await driver.getAllWindowHandles()).length;
const elem = await driver.findElement(By.id("<Id of the button that will open a new window>"));
await elem.click();
let newHandles = await driver.getAllWindowHandles();
while (newHandles.length == initialHandleCount) {
    newHandles = await driver.getAllWindowHandles();
Creating and switching between tabs
If your test code switches between multiple tabs in the same Microsoft Edge window, tabs that become inactive may not be included in the list of handles returned by Get Window Handles.  In the Internet Explorer 11 desktop application, IEDriver will return handles for all of the tabs in IE, regardless of activation state.
When using Microsoft Edge in IE mode, if your test switches focus away from a certain tab and you would like to be able to switch back to that tab later, you must store a copy of the tab's window handle.
