I'm new to Selenium and I have little knowledge of the java compilation and run process, because I always compiled and executed with the help of the IDE.

My problem

I'm trying to run a simple test with selenium (for learning purposes) to request "www.google.com" and assert that the title is the correct one.
My goal is to learn enough to use it on my work and reduce time doing manual testing on multiple browsers and OS.

My problem is that when I want to run the test from the command line it fails with a java.lang.IllegalArgumentException: Could not find class

I saw a lot of similar problems in SO but none of them helped me....

What I have done

I did the following steps:

  1. Follow this https://code.google.com/p/selenium/wiki/Grid2 and start hub+node

  2. Download the chromedriver and write this simple test class 

    import junit.framework.TestCase;
import org.junit.*;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriverService;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

import java.io.File;
import java.io.IOException;

@RunWith(JUnit4.class)
public class ChromeTest extends TestCase {

    private static ChromeDriverService service;
    private WebDriver driver;

    @BeforeClass
    public static void createAndStartService() {
        service = new ChromeDriverService.Builder()
                .usingDriverExecutable(new File("tools/chromedriver"))
                .usingAnyFreePort()
                .build();
        try {
            service.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @AfterClass
    public static void createAndStopService() {
            service.stop();
    }

    @Before
    public void createDriver() {
        driver = new RemoteWebDriver(service.getUrl(),
                DesiredCapabilities.chrome());
    }

    @After
    public void quitDriver() {
            driver.quit();
    }

    @Test
    public void testTitleDevel() {
        driver.get("http://www.google.com");
        TestCase.assertEquals("Google", driver.getTitle());
    }
}

  3. Use maven and create a pom.xml

        <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>

                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-java</artifactId>
                <version>2.46.0</version>
            </dependency>

            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.12</version>
            </dependency>
            <dependency>
                <groupId>org.hamcrest</groupId>
                <artifactId>hamcrest-core</artifactId>
                <version>1.3</version>
                <scope>compile</scope>
            </dependency>
            <dependency>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
                <version>12.0</version>
            </dependency>
        </dependencies>

        <build>
    <sourceDirectory>/Users/user1/QAScripts/AmateurTest/src/</sourceDirectory>


            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.18.1</version>
                </plugin>
            </plugins>
        </build>
    </project>

I have now the following directory structure:

Test
|--pom.xml
|--src
|------ChromeTest.java
|--tools
|------chromedriver
|------selenium-server-standalone-2.46.0.jar

  1. Run mvn dependency:build-classpath
  2. Use that classpath to compile ChromeTest.java

javac -cp "..HERE GOES CLASSPATH.." src/ChromeTest.java

user1@tororrosso ~/T/src> ls -la
total 16
drwxrwxrwx  4 user1  staff   136 Jun 12 16:43 ./
drwxrwxrwx  8 user1  staff   272 Jun 12 16:41 ../
-rw-r--r--  1 user1  staff  2316 Jun 12 16:44 ChromeTest.class
-rwxrwxrwx  1 user1  staff  1372 Jun 12 16:43 ChromeTest.java*
  1. Use the same classpath to run ChromeTest.class

java -cp "..HERE GOES CLASSPATH.." org.junit.runner.JUnitCore src/ChromeTest

But FAILS!!

Edit2: My classpath

Maybe there is a problem with my classpath. But is what maven uses....

You're trying to run class "src/ChromeTest" and I suspect your class file is not there. Assuming your target folder is in your classpath, your java command-line should be 'java -cp "blah;foo;..." ChromeTest' (since you have no package).

Also, it appears you're trying to run Selenium via Selenium Grid. To start learning Selenium, I'd suggest just running Selenium standalone and not use the grid hub.
compile via 'javac -cp "..." src/ChromeTest.java'
ok. Compiled, and ran like you said, but still the same error (see edit) :(
OMG. It was my classpath! I had to add ".:./src/:" to the beggining! Thank you!
