[🐛 Bug]: Browser version labels (stable, beta, dev, nightly) are not supported in Firefox (java)

[bonigarcia]

What happened?

Selenium 4.12.0 delivers automated browser management of Firefox through Selenium Manager 0.4.12. Nevertheless, the browser version labels (stable, beta, dev, nightly) are not supported in the Java bindings. I don't know if this problem is Java-specific or also applies to other bindings.

How can we reproduce the issue?

The following test reproduces this issue:

package org.openqa.selenium;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

class MyBasicTest {

    WebDriver driver;

    @BeforeEach
    void setup() {
        FirefoxOptions options = new FirefoxOptions();
        options.setBrowserVersion("beta");
        driver = new FirefoxDriver(options);
    }

    @AfterEach
    void teardown() {
        driver.quit();
    }


    @Test
    void basicTest() {
        driver.get("https://bonigarcia.dev/selenium-webdriver-java/");
    }

}

Even when Firefox beta is in the cache (it would need #12632), the test fails as follows:

I think the problem is GeckoDriver. What happens if you post this payload to GeckoDriver?

{
  "capabilities": {
		"alwaysMatch": {
			"browserName": "firefox",
			"browserVersion": "beta",
			"moz:firefoxOptions": {
				"binary": "path/to/binary"
			}
		},
    "firstMatch": [{}]
  }
}

Info for maintainers

Triage this issue by using labels.

If information is missing, add a helpful comment and then I-issue-template label.

If the issue is a question, add the I-question label.

If the issue is valid but there is no time to troubleshoot it, consider adding the help wanted label.

If the issue requires changes or fixes from an external project (e.g., ChromeDriver, GeckoDriver, MSEdgeDriver, W3C), add the applicable G-* label, and it will provide the correct link and auto-close the issue.

After troubleshooting the issue, please add the R-awaiting answer label.

Thank you!

Yeah, you need to delete the browserVersion from Options after you send it to Selenium Manager.
Chromedriver doesn't care what value is in browserVersion, but Geckodriver complains
