What happened?

Hello,

I'm trying to use the Seleium module to execute browser tests inside a quarkus project. I can successfully create the browser, but when I attempt to augment it through the following code

new Augmenter().augment(driver)

this fails because the reported CDP URL (chrome devtools protocol) is the URL inside the docker network Augmenting the driver allows to use new features of Selenium like BiDi.

Selenium documentation (https://github.com/SeleniumHQ/docker-selenium?tab=readme-ov-file#grid-url-and-session-timeout) states that the environment variable SE_NODE_GRID_URL must be used in such case. But this is not possible with testcontainer because the URL I need to give to SE_NODE_GRID_URL environment variable must contain the random port that testcontainers provides on start up of container.

I think it's similar to the issue https://github.com/testcontainers/testcontainers-java/issues/256 and so, it may be useful to pass this environment variable automatically before selenium container starts

Thanks

Thanks for reporting the issue. In the past, I was able to do something like is described here.

Hello @eddumelendez

Thank you for your suggestion After raising the issue, I managed to augment the selenium driver providing a random port using port binding like

        .withCreateContainerCmdModifier(cmd -> cmd.withHostConfig(
            new HostConfig().withPortBindings(new PortBinding(Ports.Binding.bindPort(randomPortSelenium), new ExposedPort(4444) , Ports.Binding.bindPort(randomPortVnc), new ExposedPort(5900))))
        )

But this only work if VNC is disabled Enabling VNC is not possible as using such port bindings seems to modify network aliases that the selenium container exposes

Hello,

I've tested with your suggestion, but same problem with VNC, container does not start (I suppose it's due to the fact that we are on a network that the VNC container does not know)

Ran into this too. Tried using newer builder pattern,

            WebDriver driver = RemoteWebDriver.builder()
                    .address(webDriverContainer.getSeleniumAddress())
                    .oneOf(browserOptions)
                    .build();

later read that this auto-applies the augmentation

changed it to

WebDriver driver = new RemoteWebDriver(webDriverContainer.getSeleniumAddress(), browserOptions);

and its working

confusing, because the only error is HTTP connect timed out on SeleniumCdpConnection

I solved my problem using

BrowserWebDriverContainer<?> chrome = new BrowserWebDriverContainer<>()
                .withCapabilities(new ChromeOptions())
                .withEnv("SE_NODE_GRID_URL", "http://localhost:4444")
                .withEnv("SE_OPTS", " --docker-video-image false")
                .withEnv("SE_RECORD_VIDEO", "true")
                .withEnv("SE_VIDEO_RECORD_STANDALONE", "true")
                .withRecordingMode(BrowserWebDriverContainer.VncRecordingMode.SKIP, File.createTempFile("video", ".mp4"));

and before augmenting driver, I change it's se:cdp capability to point to the port exposed by testcontainers and not 4444

try {
	String cdp = ((HasCapabilities)driver).getCapabilities().getCapability("se:cdp").toString();
	int cdpPort = new URI(cdp).getPort();
	int hubPort = new URL(gridHubUrl).getPort();
	cdp = cdp.replace(":" + cdpPort + "/", ":" + hubPort + "/");
	((MutableCapabilities)((HasCapabilities)driver).getCapabilities()).setCapability("se:cdp", cdp);
} catch (MalformedURLException | URISyntaxException e) {
	return;
}
