load-testing

I am trying to load test a java servlet that fetches records from an archive database. The servlet works as follows: 1-Reads in post variables from HTTP header 2-Uses variables to query database 3-Returns XML I have setup a test which I want to fire off HTTP requests with post variables however the test is not working, getting errors with J Meter. Screenshot 1 - Shows the structure of the test Screenshot 2 - Shows the CSV file I am reading from I have placed the CSV file in the same folder that my test plan is saved in! Screenshot 3 - Shows the HTTP request This is the error output: Thread

If you want to configure your VS "Load Tests" to write the results to a database server, you use the following instructions . If you want to run your "Load Tests" through powershell on a separate machine( think TFS 2018 release step ), you use the following instructions . I would like to do both, on multiple machines, in a automated manner, but there's not a great deal of documentation on this, I can run my tests like this: .\mstest /testcontainer:"C:\XXX\ABC.loadtest" But the results are kicked out to a "TRX" file rather than being placed into a database( there is some discussion on this ).

I'm building a stress testing framework for node.js services using node.js. Do you know relevant projects which I can use / look at? node.js projects that you've used and worked good? (latency, throughput etc..) Any best practices on that matter? Thanks! 来源： https://stackoverflow.com/questions/8702560/stress-testing-of-node-js-services

I have set the Max user count as 250 and test iteration in run setting as 1, So will it send 250 virtual request ??? or I have to set the Max user count as 250 and test iteration in run setting as 250 Here are some explanations about load test settings: In the Constant Load Pattern you set how the load test will create your virtual users. If you Set Pattern = Constant then visual studio will create 250 virtual users without meaning

So I am trying to load test a REST API which returns a JSON value. To do that I am creating multiple instances of the perl script. The Perl script basically calls that URL, and tries to decode_json . Obviously when substantial load is generated, it fails. Now the problem I face is- An error is displayed on command prompt but does not write that error message in a file. The error message is malformed JSON string, neither array, object, number, string or atom, at character offset 0 (before "Can't connect to 209...") at json_load_test.pl line 39. In all the three attempts below line 39 refers to:
