performance-testing

问题 I am creating a Web Load test using VS. I am testing a service that I created using WebAPI. The WebAPI works well, I am now trying to do performance/load testing on it. Here is a picture that shows how I have set up the test: When I run the test, I get a 415 Unsupported Media Type response back. Also, you can see that it states in the request that the Content-Type is there: When inserting headers, I don't see Content-Type listed as one of the options so I just typed it in. How do I correctly

问题 I need to compare the computation speed of some code, but I'm not sure what the best way to do that is. Is there some kind of built-in timer to do this? And is it possible to get the computation speed in nanoseconds, or do I need to deal with the milliseconds JavaScript usually works with? 回答1: I came across the performance API. What you're looking for is probably Performance.now() , which will give you microsecond percision. The Performance.now() method returns a DOMHighResTimeStamp,

问题 We are evaluating how to test performance on a single-page application (SPA) which relies heavily on JavaScript and dynamic content (updated via Ajax). Popular load-testing tools like Apache JMeter or Gatling are able to generate huge loads with little hardware by sending HTTP requests. But they do not process any Javascript code. We would like to measure performance as perceived by the client, that is, as perceived by end-user sitting in front of a browser (with all the rendering and

问题 We're load testing a Java 1.6 application in our DEV environment. The JVM heap allocation is 2Gb, -Xms2048m -Xmx2048m. Under load testing, the app runs smooth, never uses more than 1.25Gb of heap, and garbage collection is totally normal. In our UAT environment, we run the load test with the same parameters, the only difference is the JVM, it's allocated 4Gb, -Xms4096m -Xmx4096m, otherwise, the hardware is exactly the same with DEV. But during load testing, the performance is horrendous, the

问题 Today I'm doing my API automation testing and performance testing with Jmeter when the server is a REST API. Now the development changed to graphQL API, and I have two questions about it: 1. What is the best practice to preform the automation API and performance testing? 2. Does Jmeter support graphQL API? 回答1: Disclaimer: I work for LoadImpact; the company behind k6. If you are willing to consider an alternative, I've recently written a blog post about this topic: Load testing GraphQL with

问题 I am performing load testing on my server using jmeter. In one of my post requests, I receive a unique id in the response. I need to send this id as a parameter in the following post requests. I am new to jmeter and don't have any idea how to do this. Help would be really appreciated. 回答1: If you need to store the whole response into a variable - take the following steps: Add Beanshell PostProcessor as a child of the request which returns response you're looking for Put the following line

问题 I have a very large CSV file (8000+ items) of URLs that I'm reading with a CSV Data Set Config element. It is populating the path of an HTTP Request sampler and iterating through with a while controller. This is fine except what I want is have each user (thread) to pick a random URL from the CSV URL list. What I don't want is each thread using CSV items sequentially. I was able to achieve this with a Random Order Controller with multiple HTTP Request samplers , however 8000+ HTTP Samplers

问题 Context We wish to use "replay" web server access logs to generate load tests. JMeter had come to mind as I'd recently read blog posts about using jmeter in the cloud (e.g. firing up a number of Amazon EC2 instances to generate the load) For years I had heard of JMeter's ability to replay access logs, but in reviewing this feature I found the following. Access Log Sampler DOES: recreate sessions, i.e. handle the jsessionId token (thought it tries to approximate sessions by IP address); DOES
