Selenium Parallel tests execution

Our framework supports parallel test execution, how to enable it in your test project depends on selected Unit framework:

With Objectivity.Test.Automation.Tests.NUnit

you have to add the attribute to the test classes ParallelScope.Fixtures indicates that fixtures may be run in parallel with one another.

namespace Objectivity.Test.Automation.Tests.NUnit.Tests
{
    using System.Collections.Generic;

    using global::NUnit.Framework;

    using Objectivity.Test.Automation.Common;
    using Objectivity.Test.Automation.Tests.NUnit.DataDriven;
    using Objectivity.Test.Automation.Tests.PageObjects.PageObjects.TheInternet;

    [TestFixture]
    [Parallelizable(ParallelScope.Fixtures)]
    public class HerokuappTestsNUnit : ProjectTestBase
    {
        [Test]
        public void BasicAuthTest()
        {
            var basicAuthPage =
                new InternetPage(this.DriverContext).OpenHomePageWithUserCredentials().GoToBasicAuthPage();

            Verify.That(
                this.DriverContext,
                () =>
                Assert.AreEqual(
                    "Congratulations! You must have the proper credentials.",
                    basicAuthPage.GetCongratulationsInfo));
        }
    }
}

namespace Objectivity.Test.Automation.Tests.NUnit.Tests
{
    using global::NUnit.Framework;

    using Objectivity.Test.Automation.Tests.PageObjects.PageObjects.TheInternet;

    [TestFixture]
    [Parallelizable(ParallelScope.Fixtures)]
    public class JavaScriptAlertsTestsNUnit : ProjectTestBase
    {
        [Test]
        public void ClickJsAlertTest()
        {
            var internetPage = new InternetPage(this.DriverContext).OpenHomePage();
            var jsAlertsPage = internetPage.GoToJavaScriptAlerts();
            jsAlertsPage.OpenJsAlert();
            jsAlertsPage.AcceptAlert();
            Assert.AreEqual("You successfuly clicked an alert", jsAlertsPage.ResultText);
        }
    }
}

More info about NUnit Framework Parallel Test Execution. Please notice that currently only Fixtures may be run in parallel with NUnit 3.

With Objectivity.Test.Automation.Tests.MsTest

how set parallel test execution depends on Visual Studio version you using or test runner version. More details can be found here MsTest .runsettings .testsettings.

Please notice that Selenium IEDriver doesn't support test execution in parallel.
