Cloud-based load testing service end of life

When Visual Studio 2019 Preview 1 shipped in early December, we announced our plans to deprecate the load test functionality in Visual Studio. Visual Studio 2019 will be the last version of Visual Studio with web performance and load test features.

To give our customers plenty of notice, I also wanted to let everyone know that we plan on closing down the corresponding Azure DevOps cloud-based load testing service on March 31st, 2020.

Why

Load testing helps you ensure that your apps can scale and do not go down when peak traffic hits. Although we have been shipping our load testing tools and our cloud-based load testing service for many years, unlike our other services their adoption has not been growing. While it is difficult for me to pinpoint one specific reason for this, there are a few contributing factors, including:

  • Load testing is typically initiated for seasonal events such as tax filing season, Black Friday, Christmas, summer sales, etc. The classic example I always like to give is the NORAD Santa Tracker
  • Load testing requires a certain level of expertise to ensure you have the confidence in the results. This ranges from understanding the application & deployment architecture, designing of load tests, authoring/executing of tests at scale and analyzing the results to identify performance and application bottlenecks.
  • We’ve found that very few organizations rely on in-house expertise for this. Instead, most prefer to engage consultants to help them.

Also, frankly, I feel that our offering has fallen behind. When I look around at other offerings in this space (open source as well as commercial offerings that sometimes include consulting services) I honestly feel they are now better suited to meet the needs of our customers.

Please do not think that we are saying that load testing is not important. On the contrary – load testing, done well, remains relevant and will continue to be very important for some of our customers. But I think this need is now best addressed by making sure we have great partner provided or open source load testing options integrated into Azure DevOps.

Timeline for deprecation

  1. Visual Studio and Test Controller/Test Agent for on-premises load testing: Visual Studio 2019 will be the last version of Visual Studio with the web performance and load test capability. Visual Studio 2019 is also the last release for Test Controller and Test Agent (installed via the ‘Agents for Visual Studio’ SKU) for setting up a load test rig on-premises on in a virtual machine.

    While no new features will be added, load test in VS 2019 will continue to be supported for any issues that may arise during the support lifecycle of the product. As outlined in the product lifecycle and servicing documentation, you can continue to use the on-premises offering and will be fully supported for the next 5 years and an additional 5 years of extended support is also available should you need it. Different Visual Studio versions can be installed side-by-side on the same machine. This means that you can continue to use Visual Studio 2019 to maintain your on-premises load tests, while using a newer Visual Studio version when it becomes available in the future for other development needs.

    Visual Studio web performance tests (.webtest files) are tied to the load test functionality and is also deprecated. While it was never designed for it specifically, I know of a few customers who have used .webtest’s for other purposes such as for running API tests. I would encourage them to take a look at some of the other API testing alternatives that are available in the market that would better serve their needs. SOAP UI is a free, open source alternative to consider and is also available as a commercial option with additional capabilities.

  2. Shutting down the cloud-based load testing service: Our cloud-based load testing service will continue to run through March 31st, 2020. You can continue to use all the experiences powered by this service without interruption until then. After the service goes offline, you can continue to use the tests as outlined below while you evaluate alternatives.

    The cloud-based load testing service is also used in the following places, which will no longer be available after March 31st, 2020.

Load testing Alternatives

There are many alternatives, both free and commercial tools that you can consider. For instance, Apache JMeter is a free, popular open source tool with a strong community backing. It supports many different protocols and has rich extensibility that can be leveraged to customize the tool to your needs. Many commercial services such as Blazemeter support running Apache JMeter tests.

If you use code based tests for load testing and .NET is your platform of choice then tools such as Neoload, Micro Focus Silk Performer and Micro Focus Load Runner are options to consider.

In addition, extensions from several load test vendors such as SOASTA (now Akamai CloudTest), Apica Loadtest and Load Impact are available in the Azure DevOps and Azure marketplace.

More Information

Deprecating features is always hard and therefore not something we ever do lightly. We recognize that this announcement will be disruptive for the people that are using the service today and we will be working with affected customers to ensure they are aware of the changes. Premier support for Enterprise can be engaged for help with migrating tests to alternatives – they can be reached via email on premdevinfo@microsoft.com

If you have any further questions or concerns then please send us an email at vsoloadtest@microsoft.com or contact me directly.

This is really sad news for us. Our company have been investing more and more into this tool, and it is a large reason why most of our devs have enterprise licenses. Our top customer issue for the last couple of years has been performance, and the VS performance testing tools have probably gained us millions of dollars of revenue, and saved us million of lost revenue. It seems that a proper investigation into why the tool is not gaining more traction was not done. In my opinion, the tool has poor UX and has not had features added to it since 2012. Both of these could and should have been addressed. The price point of requiring enterprise is likely also a stumbling block to many, especially considering the fact that UX issues were never addressed. The alternative is to run the load tests in Azure, which can be very expensive very quickly. While there are alternative tools, they don't do everything better than the VS performance testing tools do. Monitoring alone is one reason to stick with the tool. At least we will have no further need to pay for an enterprise license going forward...

I just created a user voice suggestion. Vote and let's see what happens. https://developercommunity.visualstudio.com/idea/490150/open-source-performance-testing-tools-and-allow-co.html

I'm also sad to see this go. The easy way of working with load tests have been great. I think it is natural that this is not the first thing for new teams to adapt. I also belive that the test manager license have been holding this product back. It would be awesome to have it intigrated as a service and pay per consumption in your Azure Subscription.

This is a real shame. As suggested maybe open source the project to the community.

This seems premature to me. I've been doing perf testing for 6 years now and all I ever needed to use was visual studio perf testing tools. There is only one instance that I couldn't use it, it was for a VDI testing project that required more like a UI Testing approach but I don't count it as it was not a pure load testing project. I would suggest open source the entire tool as a VSIX package and let us the community support it. Anywhere we can create this idea and let the community vote on it? Regarding the Azure Load tests, I've never personally used them but if I needed there is always the possibility of using VMs with the agents installed. It's sad to see such a valuable tool just fade away when it has met my every need.

Quite disappointed on this depreciation news, We are using this across many clients and started gaining traction on Dev side. Hopefully the alternatives are easy and cheaper to use. If there is an option to keep this open I would vote for that & can get many Architects/devs attest to this feature.

I'm sad to hear that, I loved this service and one of the reasons the "Load Test as a Service" is so attractive is the fact that Load testing is typically initiated for seasonal events, so we don't need to mantain a large infrastructure. Would be nice to have a JMeter as a Service in Azure (I guess this is what Blazemeter offers).
