Could not start Selenium session: in Junit 3.8.2 test and selenium 3.4 on linux

My environment:

linux ubuntu

selenium-html-runner-3.4.0.jar

selenium-java-3.4.0

selenium-server-standalone-3.4.0.jar

to build I do:

 javac -cp "/usr/share/java/junit.jar:/home/me/ushare/hobo/selenium/selenium-html-runner-3.4.0.jar:." TestHobo2.java

to run selenium-server: 

java -jar selenium-server-standalone-3.4.0.jar

to run the test I do: 

java junit.textui.TestRunner TestHobo2

and I get:

java.lang.RuntimeException: Could not start Selenium session:

at com.thoughtworks.selenium.DefaultSelenium.start(DefaultSelenium.java:114) at com.thoughtworks.selenium.SeleneseTestBase.setUp(SeleneseTestBase.java:139) at com.thoughtworks.selenium.SeleneseTestBase.setUp(SeleneseTestBase.java:108) at com.thoughtworks.selenium.SeleneseTestCase.setUp(SeleneseTestCase.java:113) at TestHobo2.setUp(TestHobo2.java:10) at com.thoughtworks.selenium.SeleneseTestCase.runBare(SeleneseTestCase.java:289) Caused by: com.thoughtworks.selenium.SeleniumException:

Here is my test case:

import com.thoughtworks.selenium.*;
import java.util.regex.Pattern;

public class TestHobo2 extends SeleneseTestCase {
    public void setUp() throws Exception {
        setUp("http://www.example.com/", "*chrome");
    }
    public void testGetLink() throws Exception {
        selenium.type("name=p_loc", "groove");
        selenium.click("css=input[type=\"Submit\"]");
        selenium.waitForPageToLoad("30000");
    }
}

Edit 2017/07/20 More info:

I am using Firefox version 52.0.2 (64-bit).

Should I be getting the following after the build?

Note: TestHobod2.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details.

Solution

  • Are you sure that you have properly defined on which ip address and port is selenium running? Run your selenium server and put http://127.0.0.1:4444/wd/hub/ link into your browser. Try to create new session manually (click on create session and select browser, see image below), new browser blank window should appear. If this is working correctly than selenium server is ok. Then there can be problem with connection between server and your runner.
    screen of selenium hub with create session option
    Do you have correctly setup selenium driver? For example I'm using 

    new RemoteWebDriver(new URL("http://127.0.0.1:4444/wd/hub/"),DesiredCapabilities.firefox())

    EDIT1: Show example of setUp method which create instance of RemoteDriver, create new browser session and fill url.

    WebDriver driver = new RemoteWebDriver(new URL("http://192.168.4.52:4444/wd/hub"), DesiredCapabilities.firefox());
driver.manage().window().maximize()//maximaze window as possible
driver.get("www.google.com"); //navigate to google, i.e. fill url into opened session
