MSTest-Cross browser testing C# with Selenium?-how to run C# Selenium tests against multiple browsers

Question

At the moment my tests are running only in Firefox, because that is the driver which initialize at last. I need to run my tests on both Firefox and Chrome. Parallel or serially. But it should be automatic.

Below is my example test-code:.

namespace TestOne
{
    [TestClass]
    public class UnitTest1
    {
        public static IWebDriver driver;

        [TestInitialize]
        public void BeforeEveryTest()
        {
            driver = new ChromeDriver();

            driver = new FirefoxDriver();
        }

        [TestMethod]
        public void NavigateToGoogle()
        {
            driver.Navigate().GoToUrl("http://google.com");
        }

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

What are the options to run this test for both Chrome and Firefox? When using the C# testing tools (e.g. mstest.exe or vstest.console.exe)

I think you can use a .RunSettings as described in the MSDN documentation.

<?xml version="1.0" encoding="utf-8" ?>
<RunSettings>
  <TestRunParameters>
    <Parameter name="browser" value="chrome" />
  </TestRunParameters>
</RunSettings>

If you make a file for Firefox and Chrome you can run the tests from the command-line with VStest.Console like this:

vstest.console myTestDll.dll /Settings:Chrome.RunSettings /Logger:trx
vstest.console myTestDll.dll /Settings:Firefox.RunSettings /Logger:trx

Your test would look like this:

    [TestInitialize]
    public void BeforeEveryTest()
    {
        if ( TestContext.Properties["browser"].ToString() == "chrome" ) {
          driver = new ChromeDriver();
        } else {
          driver = new FirefoxDriver();
        }
    }
