Vote for Sofie

My daughter got a new pair of glasses. The shop asked if she wanted to participate in an election. They took her picture and uploaded it to their website. We could then vote for her on that website.

Trying to vote multiple times was blocked for the same IP Address. That was something I wanted to beat with automation. Here’s my run for president with the use of WebJobs, BrowserStack and selenium automation.


browserstackSignup for Windows Azure and BrowserStack. Take a look at the documentation for writing automate test scripts in C#. When you’ve logged in to BrowserStack it contains your user and token. Just copy-and-paste into your code.


seleniumYou can run a console application as a webjob. Start Visual Studio and Create a Console Application. Add the nuget-package Selenium.WebDriver and use the code below

static int Main(string[] args) {
    IWebDriver driver;
    DesiredCapabilities caps = DesiredCapabilities.Firefox();
    caps.SetCapability("browserstack.user", "YOUR_USER");
    caps.SetCapability("browserstack.key", "YOUR_KEY");
    driver = new RemoteWebDriver(
        new Uri(""), caps
    // write the title of the page loaded
    // try to click the vote button
    IWebElement button = driver.FindElement(By.Name("submit-vote"));
    // if element not found right away, retry for the next 10 seconds ...
    var result = 1;
    try {
        IWebElement message = driver.FindElement(By.ClassName("message"));
        // When Thank you is displayed the vote was successful
        if (message.Text.ToLower().StartsWith("Thank you")) { result = 0; }
    catch {
    finally {
    return result;

Run the console application to see it working on your local machine!

Create a zip archive from the files in the bin folder (your_console_app.exe and WebDriver.dll). This is the content for your webjob.

webjobsNow create a new website on the windows azure portal. Add a webjob and upload the created zip archive as the content. Set a schedule and your done.



In the source code you see the return code is set to 0 when “Thank you” is displayed else the return code is 1. The webjob uses this return code for the status of the run.

On the AzureJobsextension the date/time and the status are showed in a table. The url is Return code 0 displays Success and code 1 displays Failed. No need to go into the logging for every run to see if the vote was registered.

Time’s up

After running the webjob for serveral weeks it started to Fail every time. The logging showed my BrowserStack free Automated testing time was used up.

[> abaad4: SYS INFO] Status changed to Initializing

I removed the webjob in the Windows Azure Portal as it would keep failing. Hope it was enough to win the election 😀 Results are expected first week of 2015.


Using BrowserStack automated (selenium) testing and Azure Webjobs I automatically voted on a website that didn’t allow multiple votes from the same IP Address. This post describes how I did it.
