Apache jmeter documentation3/31/2023 ![]() We need to add it to all the upcoming request headers so that the protected services will verify our identity. ![]() Now we have a JWT token for requesting secured resources from our Library. If you are interested in more details about JSON Web Tokens and Bearer Authentication I would recommend to start from here on JWT. If this is what you got as a response, you can remove the temporary View Results Tree component and proceed further. If everything was done correctly we should get a response similar to what we have below:ħ. ![]() To verify that we get a JWT token back, add a temporary View Results Tree listener.Ħ. That will add a corresponding header to all the requests we send to our services.ĥ. Add an HTTP Header Manager before the HTTP Request Sampler we added earlier and add a header Content-Type: application/json as in the screenshot below. The service I use in this article accepts/sends data as a JSON, so we have to indicate it in the request header.Ĥ. So add a parameter to the Authentication request and provide any JSON with a valid email and non empty Password fields. The service does not do sophisticated user checks, but due to the validation model of the service, it requires valid login credentials. Configure the HTTP Request Sampler to send a request to the Library.Authentication service. More details about what a JSON Web Token is can be found on. Since the book search and order services are protected by JWT, we need to request a valid security token from the Library.Authentication service. Now, add an HTTP Request sampler to the newly created Thread Group. Since the mentioned services are HTTP based RESTful services, we need the HTTP Request Sampler to perform the service call.Ģ. Run the same command for all 3 services and we are ready to go! How to Do Performance Testing For Microservices with JMeter The dotnet run result should be something similar to this: Those who are interested in more information about the dotnet cli tool can find more details here on Microsoft. After cloning the project locally, open the project folders in a command line tool and run dotnet run to start the corresponding service. The Library project contains three services. Net Core official website if you don’t have it already. The services that are used in the current tutorial can be found on the github repository called Library (I didn’t try to be creative here). We are not going to do anything complicated here anyway and the scripts used below are very easy to read. Don’t feel upset if you are not familiar with Groovy. Since we are going to use Groovy in this article, a very basic knowledge of it would be nice to have. How to Prepare For Performance Testing Microservices Prerequisites For simplicity’s sake, all the information about books is hardcoded so no DB of any sort will be used. We will create a simple JMeter test project for the set of microservices mentioned above that will test the group of services in the same thread. These are microservices because they are small, loosely coupled, scalable and each solves its own problem. The first one is responsible for user authentication, the second one acts as a bookshelf service helping to find information about books, and the last one allows ordering books. Let’s imagine we have a group of services. A load testing scenario for microservices should test the interactions between these services. In this blog post we will demonstrate one of the possible scenarios of performance testing Microservices with Apache JMeter™. The advantages of microservices have resulted in more users and growing popularity, but at the same time the challenges of developing and testing Microservices surface.
