WebDriverError: unknown error: Chrome failed to st

What I'm trying to achieve Successfully run my protractor tests on headless chrome on Ubuntu 14 non gui.

Set up Using multiple reference pages I have managed to successfully install: Xvfb Chrome latest browser Protractor 3.3.0 Java 7 (also tried with Java 8) and also set the LOCAL_HOME. Also, managed to start the Xvfb using this reference.

Protractor conf

exports.config = {
    baseUrl: 'http://<qa environment>',
    framework: 'jasmine',
    seleniumAddress: 'http://localhost:4444/wd/hub',
    jasmineNodeOpts: {
        showColors:true,
        defaultTimeoutInterval: 2500000
    },
     capabilities: {
    'browserName': 'chrome'
  },

    specs: ['administration/*-spec.js'],  //'signinandout/*-spec.js', 'homepage/*-spec.js',
    onPrepare: function(){
        //browser.driver.manage().window().setSize(1280, 1080);
    }
}

回答1:

Check your Google chrome Version and its compatibility with the chrome driver.

You can check that from the Chromedriver Site and download the compatible version.

It worked for me.

回答2:

probably your window screen size is not matching try giving maximize in onPrepare:

onPrepare: function(){
browser.driver.manage().window().maximize();
    }

回答3:

Open your project and Please update your npm modules by the following command.
```
project_root:\> npm update
```
Now update your selenium driver to the latest version using the following command
```
project_root:\> webdriver-manager update  
```
Run your tests again.

Error due to Xvfb display is not specified here. Here , Selenium scripts are running using headless browser testing concept which is without GUI.

Hope u have used chromedriver, chrome binaries and XVfb. here chromedriver is initializing chrome binaries but chrome binary not able to sits on the monitor with XVfb .Thats y its throwing error as " Chrome failed to start:exit abnormally"

please follow the below steps before executing ur script.Example:(Execute this cmd in ur Unix server (ex.putty))

usr/bin/Xvfb :2 -ac -screen 0 1280x1024x24 &

export DISPLAY=:2

It will work definitely.
