Selenium and Edge Dev (Chromium based)

Just to close this issue, based on the answer by Jools, I have updated my test (using the latest version of WebDriverManager) and now it is working:

import static org.hamcrest.CoreMatchers.containsString;
import static org.hamcrest.MatcherAssert.assertThat;

import org.junit.After;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.edge.EdgeDriver;
import org.openqa.selenium.edge.EdgeOptions;

import io.github.bonigarcia.wdm.WebDriverManager;

public class EdgeDevTest {

    private WebDriver driver;

    @BeforeClass
    public static void setupClass() {
        WebDriverManager.edgedriver().setup();
    }

    @Before
    public void setupTest() {
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.setBinary(
                "C:\\Program Files (x86)\\Microsoft\\Edge Dev\\Application\\msedge.exe");
        EdgeOptions edgeOptions = new EdgeOptions().merge(chromeOptions);
        driver = new EdgeDriver(edgeOptions);
    }

    @After
    public void teardown() {
        if (driver != null) {
            driver.quit();
        }
    }

    @Test
    public void test() {
        driver.get("https://bonigarcia.github.io/selenium-jupiter/");
        assertThat(driver.getTitle(),
                containsString("JUnit 5 extension for Selenium"));
    }

}

Just got it working. My setup is a little different from yours because I'm using a grid, but it should be fairly similar.

For me, when requesting a driver from the grid I use the chrome capabilities:

m_capability = DesiredCapabilities.chrome();
m_capability.setCapability( "browserName", "chrome" );

So in your case I guess you'll want this instead:

driver = new ChromeDriver();

When launching a node I specify the chrome driver to point to the edge driver (I have it on the PATH, so no need for absolute path)

java -Dwebdriver.chrome.driver=msedgedriver.exe ...

So in your case you'll want this instead:

System.setProperty("webdriver.chrome.driver",
        "C:\\Users\\boni\\Downloads\\msedgedriver.exe");

Another thing to remember is to have the location of Edge executable (see below) on your PATH

For Edge Dev you'll want to add:

C:\Program Files (x86)\Microsoft\Edge Dev\Application\

Or if you're using Canary, it's probably:

C:\Users\boni\AppData\Local\Microsoft\Edge SxS\Application\
