Selenium/Chromedriver automation hanging when run as executable

Question

I am trying to create a simple automation task. For now I want to log in to the webpage. This all works fine when I run the test in Visual Studio 2017. However this will need to be executed as an exe on regular interval in windows system. When I run the executable it hangs after displaying:

Starting ChromeDriver 2.32.498550 (9dec58e66c31bcc53a9ce3c7226f0c1c5810906a)

on port 9515

Only local connections are allowed.

I understand this is just info not an error per most SO posts related to this issue such as - When running WebDriver with Chrome browser, getting message, "Only local connections are allowed" even though browser launches properly (note: my browser does not launch)

How do I run the test code as an executable? Do I have to write additional code to invoke the test when running as executable?

        driver = new ChromeDriver();
        driver.Manage().Window.Maximize();
        driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(30));
        driver.Navigate().GoToUrl(this.baseURL);
        driver.FindElementById("UserName").SendKeys("user");
        driver.FindElementById("Password").SendKeys("12345");
    }

    [TestCleanup()]
    public void MyTestCleanup()
    {
        driver.Quit();
    }

    [TestInitialize()]
    public void MyTestInitialize()
    {
    }
}

}

The cmd window message after launching exe

Thank you for your time.

Did you run in Visual Studio and as EXE on same machine? If so, it should pass as run in Visual Studio because both use same chrome and chromedriver.exe. — yong, Sep 20 '17 at 23:39
the issue is chrome driver hangs & you need to quit all chromedriver process before invoking the exe again. Example cmd command can be used as first part of your code: "taskkill /F /IM chromedriver.exe /T" which needs to be run on cmd — thebadguy, Sep 21 '17 at 04:11

To run as EXE I think there are two options:

1) not with selenium server or grid
. you need package the chromedriver.exe with your code into the EXE
. you code need to calculate the path of chromedriver.exe in runtime, because you don't know user will put the EXE in which folder
. specify chromedriver.exe by ChromeOptions to tell selenium where to find it when create driver instance

Shortage of this way: a chromedriver.exe of certian version support limited chrome verions, not all chrome verions, you need to tell user which chrome the EXE support.

2) use selenium server/grid
. you code need accept selenium server/grid address from a config file which user can modify it
. create RemoteWebDriver instance with above address, not ChromeDriver in code
. no need to package chromedriver.exe with your code

Shortage of this way: A selenium server/grid need be ready before execute EXE, But your code no need to consider the compatibility of chrome and chromedriver.exe, because they had been considered when setup selenium server/grid.

For option 1, you can use config file as option 2 to setting the path of chromedriver.exe by user self. — yong, Sep 21 '17 at 00:03
