I have read a few questions here about stress testing and people commonly recommend ab selenium jmeter openSTA but these all seem based around Apache and Java and Scripting etc. Selenium seems the best option because you record the actual use of you site which simulates UI load and database requests etc and then play it over an...

Hi. I have some basic questions around understanding fundamentals of Performance testing. I know that under various circumstances we might want to do - Stress Testing - Endurance Testing etc. But my main objective here is to ensure that response time is decent from application under a set of load which is towards a higher end or in leas...
Visual Studio 2008 has a test type called a Load Test. It looks like I can just drop a collection of other tests into it, give it a test profile (say, 50 users constantly hitting the program), a running time, and let it run. What isn't clear to me, is how to actually setup the tests it consumes. I need to launch a instance of the pr...
Hello, Recently I start to work with VSTS and I made some test scripts to run against an website. The scripts consists basically of a synchronous WebService request. I ran this script with 2000 users and checked the Current Connections Performance Counter but it was never higher than 17. The amount of Tests Running is always near 150 ...

Even though app is relatively simple there a few places where it brings up a popup window with one button on it. When user clicks that button - a response return some text back to the pop up window....
I have a PHP application that will be accepting image uploads and I'm expecting ~20,000 in about 2 days. I have no concept of how much traffic my server can handle... How would I go about simulating this beforehand to make sure it works ok? I know Rails has systems that make testing easy, but what tools might I use to simulate uploads an...
Is there a rule on how often an application should be stress or load tested? I normally do it before putting into production a new version, when the hardware changes or when the expected amount of users is known to change. But today i'm asked if this should be a standard practice for an application that is in production even if no chan...

I have DNS pointing all 200 IPs at the client box on which the virtual clients will be running. Does anyone know how to configure this? I have been assured that it can be do...

I'm looking for a windows utility to consume CPU at a specified percentage so that I can test my app under conditions of restricted processor resources. I googled around and saw a reference to CPUGRAB.exe, but can't find a download location. ...

Hello, I tried JMeter and it's great but fails in what I need. Basically I'm testing an ASP script that returns frameset to the client. When frameset renders it calls a couple of other asp scripts which render in separate frames. When I test this with JMeter I only get results for the output of the main script that renders first. JMete...
I've got a somewhat complex web application, containing Flash and javascript on the client side and PHP functionality server side. The PHP functionality contains system calls (exec()) to merge/edit/create files with gnu software (*nix environment) as well as api calls to REST services for uploading these files (this will be done with cro...
I want to examine exactly how my code operates when using other libraries to which I do not have the code for. Whilst I can do this online (i.e. with FileMon, RegMon and TCPView from SysInternals), I was wondering if there was a good offline method that would allow me to run up my code in a virtual machine, shutdown the virtual machine a...
Hi All, Can someone recommend a load testing tool which allows you to either - a) replay an IIS (7) log(s) to simulate a real live site daily run. b) import a CSV or equivalent list of URLS so we can achieve a similar thing as above but at a URL level. NEW: c) A .net API so I can create simple tests easily from my list of URLS is als...
I've been tasked with stress/load testing our company web site out of the blue and know nothing about doing so. Every search I make on google for "how to load test a web site" just comes back with various companies and software to physically do the load testing. For now I'm more interested in how to actually go about setting up a load t...
My Ruby on Rails application is mostly contained behind a login page. I'd still like to be able to stress test these pages, as they have some heavy database access. Sending the username and password into a post for my login isn't difficult, but the Authenticity Token keeps changing, which makes my tests unrepeatable. Is there a way to...
Hi, We have some users which are using lower cpu powered machines and they're encountering slow rersponse times using our web application. Is there anyway for me to be able to do testing so that I can simulate lower cpu rates? For example, I have 2.3 ghz right now computing power, can i lower it to somehow 1.6 ghz or lower so that i m...
Hi, I would like to do some stress testing to a WebSocket based application. Anyone knows a tool that may help me in this task? Update: I forgot to mention, but I'm favoring open source or free tools, given that the tests I'm performing are not for production. Thanks, Luís M. Costa ...
