Introduction to Visual Studio Online cloud stress testing

If a large system, e-commerce or external http://www.aliyun.com/zixun/aggregation/36698.html "> Public service, often face a large number of simultaneous online users (concurrent users), How do you make sure your system is available, reliable, and effective? Most developers and systems teams know that load stress tests (stess test/load test) can be performed prior to the launch to ensure that the application is under a lot of pressure and that the system is bottle-neck and tuned as early as possible, such as adjusting system architecture, programming, and leveraging Cache, dispersing machines and using cloud services, or scale-up/scale-out.

How many concurrent users? Change it to you right now! Cloud stress test on Visual Studio Online (Cloud Load test)

But before the stress tests, the machine that needs to be prepared for pressure is the agent, the number of machines required is usually more than 10 to simulate a large number (TENS/100,000) while online users (concurrent users), even within the enterprise you are ready for these machines and environment, When the implementation of the pressure test, immediately enterprise network bandwidth is eaten, can not simulate the real online operation. You can now use the resilient Cloud stress test (Cloud Load test) provided by Yunping Visual Studio Online to automatically generate these pressures through the cloud, quickly and easily, saving you time to prepare the machine and cost and install/set the relevant software. Visual Studio consumers use the same IDE (required with the Visual Studio Ultimate version) to manage, set up, execute load stress tests, and generate test reports to quickly identify bottlenecks in the system.

The cloud pressure test service is now public preview for you to use, with a free amount of 15,000 virtual user minutes (virtual user/minutes) per month, for example: Free amount can simulate 1,500 online users for 10 minutes (1,500 x 10 = 15,000), because Visual Studio online is one of Windows Azure services and, if needed, can be purchased online via the Windows Azure Billing mechanism, how to buy more load test capacity for accounts.

Now look at demo!.

[Simple Screenshot]-recording WEB performance tests

Establish a WEB performance test. (In Visual Studio Ultimate 2013)

Your Web browser opens.

Enter the URL of the Web site you want to test.

Use applications, such as Web e-business applications, to search for products and add them to the shopping cart in a way that is expected to be used by customers.

The recorder will knot the HTTP requirements and responses.

When finished, stop recording.

Edit the test properties to specify the performance target. For example, you can select a page and set the response time target for that page to 1 seconds.

Build a Load test

Create a new load test in the WEB performance and load test project. (In Visual Studio Ultimate 2013)

When the Load Test Wizard appears, select the Load mode step. Changing the load pattern to a gradual execution of the load will gradually add the user over time. This can be based on the real network use environment, set the situation of stress testing to achieve as much as possible to meet the real test

Select the test mix step.

Join the WEB Performance test you established.

Move the WEB performance test to the test list that you want to execute. Is the test scenario you've recorded before.

When you complete the wizard, the Web performance test is added to the load test and appears in the Load Test Editor.
