Load test your app in the cloud using Visual Studio

Check your app or web site's performance before you launch it or deploy updates to production. Find problems before your customers do. Start running cloud-based load tests in almost no time with Visual Studio and Team Services.

This example shows how to execute a load test using Visual Studio. You can also run cloud-based load tests directly using your Team Services portal. If you prefer to run your tests in a local environment rather than in the cloud, see Use a lab environment for your devops.

In this example, you'll learn how to:

Prepare your environment

  • Download and install Visual Studio Enterprise, if you don't already have it.

  • Create your Team Services account, if you don't have one already. You can have any access level assigned do you in Visual Studio Team Services when you use Visual Studio Enterprise to run load tests.

  • If you don't have a load test project, use our sample load test project with your web site or app. Just provide the address for the web site that you want to test. Or, if you have a load test project, jump ahead to set up your load test project to run load tests in Visual Studio Team Services.

Get the sample load test project

  1. Download the sample load test project, unblock the zip file in its Properties dialog, and unzip the files into a local folder on your computer.

  2. Open the GettingStartedWithLoadTesting.sln solution in Visual Studio Enterprise.

  3. Open the SampleWebTest.webtest file. Replace the URL with the URL of your app's web page.

    Open SampleWebTest.webtest. In Properties window, replace URL with your web page address

Connect to your Visual Studio Team Services account

Before you can run load tests in the cloud, connect Visual Studio to your Team Services account.

  1. If you haven't already, sign up for a Visual Studio Team Services account. Learn more about signing up for Visual Studio Team Services.

  2. In Team Explorer, connect to your Team Services account.

    Connect to your Team Services account

  3. Connect to one of your team projects.

    Select Team Projects

    • If you haven't connected to your Team Services account before, add your account to the server list.

      Click Servers to add your Visual Studio Team Services account

    • Enter your Team Services account name ({youraccount}

      Enter your account name

    • If you're prompted to sign in to Team Services, do that.

  4. Select your Team Services account from the list, then choose your team project. Now you can connect.

    Choose your team project

Run and analyze your load test

  1. In Solution Explorer, open the load test that you want to run.

    Solution Explorer: double-click your load test

  2. To run your test closer to where your users are, select a location closer to your users.

    Edit load test to set location

    Select location

  3. Now run your load test. This will run in the cloud using Team Services.

    On the load test toolbar, click Run

    Your test appears in the queue and waits for its turn to run. When Team Services is ready to run your test, the test status changes to "Acquiring resources".

    Your load test appears in the queue

    A large test run might take up to 10 minutes while Team Services sets up virtual machines and agents for you.

  4. You can watch your app's performance while the test runs. Look at the details to review errors, warnings, or other information about your test.

    Running your load test show the performance

  5. When the test is done, download the report to view the results.

    Click Download to save the report

    Click View Report to view results

    The results include performance counter data, threshold violations, and error information.

  6. Review your test's details. Find the number of users where your app's performance fails to meet your requirements by examining the step load pattern for virtual users.

  7. Fix any performance issues that you find in your app's code, then rerun the test.

  8. To simulate real-world loads more closely, you can refine your test by specifying web performance test properties, load test scenario properties, and run settings properties.
