Selenium Grid setup in Selenium Java - Test Execution Trace

Test Overview

This test verifies that Selenium Grid is correctly set up by connecting to the Grid hub, launching a browser node, navigating to a web page, and checking the page title.

Test Code - JUnit 5

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.junit.jupiter.api.*;
import java.net.URL;

public class SeleniumGridSetupTest {

    private WebDriver driver;

    @BeforeEach
    public void setUp() throws Exception {
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setBrowserName("chrome");
        driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capabilities);
    }

    @Test
    public void testOpenPageAndCheckTitle() {
        driver.get("https://example.com");
        String title = driver.getTitle();
        Assertions.assertEquals("Example Domain", title);
    }

    @AfterEach
    public void tearDown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and DesiredCapabilities for Chrome browser are set	Test environment ready to connect to Selenium Grid hub	-	PASS
2	RemoteWebDriver connects to Selenium Grid hub at http://localhost:4444/wd/hub with Chrome capabilities	Browser node is launched by Selenium Grid	-	PASS
3	Driver navigates to https://example.com	Browser displays the Example Domain page	-	PASS
4	Test retrieves the page title	Page title is 'Example Domain'	Assert that page title equals 'Example Domain'	PASS
5	Driver quits and browser node closes	Browser closed, resources released	-	PASS

Failure Scenario

Failing Condition: Selenium Grid hub is not running or unreachable at http://localhost:4444/wd/hub

Execution Trace Quiz - 3 Questions

What does the RemoteWebDriver do in this test?

A Starts the Selenium Grid hub

B Runs tests locally without Grid

C Connects to Selenium Grid hub and launches a browser node

D Checks the page title

Key Result

Always verify that the Selenium Grid hub URL is correct and the hub is running before running tests that use RemoteWebDriver.
