How to run any (Chrome, Firefox, PhantomJS) browse

问题:

My Question or Problem = I cannot run any browser with selenium remote server, how do I fix this?

My environment:

• Operating System Windows 10
• I'm using eclipse(Version: Neon Release (4.6.0)) with java 1.8
• selenium Web driver 3.0.0
• selenium-server-standalone-3.0.1.jar

I start selenium-server-standalone in cmd. ("selenium-server-standalone-3.0.1.jar" the file is stored in the utilities folder on my c drive )

C:\Windows\system32> cd\
C:\> cd utilities
C:\Utilities> java -jar selenium-server-standalone-3.0.1.jar

Then selenium-server-standalone starts and everything looks fine

When I run my tests

Eclipse provides this error:

Driver info: driver.version: RemoteWebDriver

In cmd I received this error:

My code looks something like this for the remoteDriver part that I have added. I have included the class and constructor

public class browser {
    private  browser (WebDriver driver){ 
        browser.driver = driver;
    }

    public static void runRemoteDriver(){
        try {
            WebDriver webDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),DesiredCapabilities.firefox());
            new browser (webDriver);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}   

回答1:

I copied all the driver to folder where I store the "selenium-server-standalone-3.0.1.jar" file. Then it worked!!!

I started server with cmd command:

java -jar selenium-server-standalone-3.0.1.jar

then in you code you must specify which browser you want to run for example:

    WebDriver webDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),DesiredCapabilities.firefox());
    WebDriver webDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),DesiredCapabilities.chrome());
    WebDriver webDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),DesiredCapabilities.phantomjs());

I think you are missing the path for your driver.exe file. You have two options:

1.you can either use System.setProperty(), in the way you do generally.

2.you can start the RemoteDriver using the path as shown below.

java -Dphantomjs.binary.path=phantomjs.exe -jar selenium-server-standalone-3.4.0.jar

and this line of code is responsible for establishing the connection.

WebDriver webDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),DesiredCapabilities.firefox());
