从Eclipse访问URL时获取org.apache.http.conn.HttpHostConnectException

Question

We are using BrowserStack for a project.

The portal we are testing is whitelisted for our IP.

And we access internet behind proxy.

While running below code snippet:

public class DemoClass {

public static final String USERNAME = "<Username>";
public static final String AUTOMATE_KEY = "<Key>";
public static final String URL = "https://" + USERNAME + ":" + AUTOMATE_KEY 
+ "@hub-cloud.browserstack.com/wd/hub";

public static void main(String[] args) throws Exception {
 String baseUrl;
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("browser", "IE");
caps.setCapability("browser_version", "7.0");
caps.setCapability("os", "Windows");
caps.setCapability("os_version", "XP");
caps.setCapability("browserstack.debug", "true");
caps.setCapability("browserstack.local", "true");
System.getProperties().put("http.proxyHost", "<Proxy URL>");
System.getProperties().put("http.proxyPort", "<Proxy Port>");
WebDriver driver = new RemoteWebDriver(new URL(URL), caps);
....

We are getting below error:

Exception in thread "main" 
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a 
new session. Possible causes are invalid address of the remote server or 
browser start-up failure.

How to resolve this issue?

Answer 1

Here is the Answer to your Question:

I din't find any significant issue in your code block as such. But here are a few points you need to take care:

1. When you do WebDriver driver = new RemoteWebDriver(new URL(URL), caps); remember to import java.net.URL;
2. I have observed you handling the base exception as public static void main(String[] args) throws Exception rather you may consider to be precise by public static void main(String[] args) throws MalformedURLException
3. You mentioned We are using BrowserStack for a project but you haven't mentioned whether you are using BrowserStack Automation or BrowserStack Running local tests .
4. Assuming you are using BrowserStack Automation you need to remove caps.setCapability("browserstack.local", "true"); from your code.
5. Incase you are using BrowserStack Running local tests you need to mention caps.setCapability("browserstack.local", "true"); in your code.

6. Assuming you are using BrowserStack Automation , here is your own code block along with some simple tweaks which successfully executes on "BrowserStack Automation":

    package SeleniumGrid; import org.openqa.selenium.WebDriver; import org.openqa.selenium.remote.DesiredCapabilities; import org.openqa.selenium.remote.RemoteWebDriver; import java.net.MalformedURLException; import java.net.URL; public class Q44196893_IE_BrowserStack { public static final String USERNAME = "<Username>"; public static final String AUTOMATE_KEY = "<Key>"; public static final String URL = "https://" + USERNAME + ":" + AUTOMATE_KEY + "@hub-cloud.browserstack.com/wd/hub"; public static void main(String[] args) throws MalformedURLException { String baseUrl; DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("browser", "IE"); caps.setCapability("browser_version", "7.0"); caps.setCapability("os", "Windows"); caps.setCapability("os_version", "XP"); caps.setCapability("browserstack.debug", "true"); System.getProperties().put("http.proxyHost", "<Proxy URL>"); System.getProperties().put("http.proxyPort", "<Proxy Port>"); WebDriver driver = new RemoteWebDriver(new URL(URL), caps); driver.get("http://google.com/"); System.out.println("Title is : "+driver.getTitle()); driver.quit(); } }

Answer 2

Set your proxy in _JAVA_OPTIONS under system variables and it will start working. I faced the same issue and it get resolved by providing proxy for both http and https for _JAVA_OPTIONS .
