stress-testing

问题 I am working on a Java app running in Tomcat with Mysql. I am wondering about what strategy to take for this task. So far the only tools I know of for the job are JMeter and Siege. I also don't know what strategy to take with these tools. Do I just test every request I can make or is there a general practice for identifying pain points? 回答1: We perform a lot of load testing services on behalf of our clients - and we always recommend an agile, iterative approach to load testing. This is

问题 I created a Selenium hub and 3 chrome nodes using docker. i can see the 3 chrome instances are up and running in the docker Now how do i stress test a web application. please suggest the steps to run test on selenium grid inside the docker. 回答1: You may start with this simple Python test #!/usr/bin/env python2.7 SELENIUM_HUB = 'http://localhost:4444/wd/hub' from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities driver = webdriver.Remote(

问题 I have ThreadGroup1 which performs login operation where it is getting Credentials from CSV file using CSV Dataset Config and saves username and password in two different variables like: ${__setProperty(USERNAMEGlobal, ${USERNAME})} ${__setProperty(PASSWORDGlobal, ${PASSWORD})} Now in ThreadGroup2 I use these credentials using: ${__property()} it works fine for a single user, but if I try multiple users (requests) last value overrides the previous all values and ThreadGroup2 receives only the

问题 I want to load test a URL by hitting it few hundred times at same millisecond . I tried JMeter but I could hit 2 request at same millisecond. This seems to be problem that my machine cant create threads fast enough . Is there any solution to the issue ? 回答1: In JMeter you can use synchronizing timer setting it to 100, this way all threads will wait until there are 100 available and hit the server: http://jmeter.apache.org/usermanual/component_reference.html#Synchronizing_Timer Another

问题 Could you please explain, how load or stress test is released inside Visual Studio when the test is oriented on the number of simultaneous users? Example: Step user count: 0 Initial user count: 2. Run duration and step duration: does not important really because user count is always the same (2), let it be 30 seconds for run duration and 30 seconds for step duration. It is a kind bit weird configuration for the test but it helps to show the main idea of my question. Web serivce is able to

问题 I want to stimulate say 1000+ users logging in/do stuff/etc and staying in the system, for say 5 minute before logging out/doing something else. While these 1000+ are staying, I will loop it through so additional 1000+ users are sent in and so on - sort of like trying to cram as many users onto the server as possible and keeping them there while cramming more. Is it possible to do something like this? I did some looking around, and there is a keepalive option in jmeter, but how long does this

问题 I am trying to test my Android app using Monkey. There they say use this command, $ adb shell monkey -p your.package.name -v 500 In my app, I have package name as travelceylon\client so if I give the command as: adb -e shell monkey -p travelceylon\client -v 1000 ...it will show errors like this: :Monkey: seed=0 count=1000 :AllowPackage: travelceylonclient :IncludeCategory: android.intent.category.LAUNCHER :IncludeCategory: android.intent.category.MONKEY ** No activities found to run, monkey

问题 Long story short; I am testing a system to purge entries from a table over a network connection, and the functionality is predicted to handle over 2 billion entries at most. I need to stress test this to be certain. Here's my test script (At best it's able to generate 9.8 million in ten minutes.) DECLARE @I INT=0 WHILE @I <2000000001 BEGIN INSERT INTO "Table here" VALUES(@I) SET @I=@I+1 END Can anyone suggest anything, or give me an idea what the upper limits of my test environment might be

问题 I am using Siege 3.0.3 from CentOS 6.4. My question is : how does 'Siege' supports HTTPS protocol? So far using this tool the HTTP sites testing is OK. But, I am facing certain issues (all described below) while dealing with the HTTPS sites. As suggested by someone, to make HTTPS work I have compiled siege with openssl. For doing this, I followed the procedure as mentioned in the below site. http://drewsymo.com/how-to/installing-siege-stress-tester-on-centos-6-3/ In brief, I ran the following

问题 I am stress testing my MonoDroid app. Each loop through the test involves giving the app a simple input, then updating the UI. I am consistently seeing the following after 97 loops through the stress test. Afterwards, the UI no longer updates: [Surface] dequeueBuffer failed (Invalid argument) [ViewRootImpl] Could not lock surface [ViewRootImpl] java.lang.IllegalArgumentException [ViewRootImpl] at android.view.Surface.nativeLockCanvas(Native Method) [ViewRootImpl] at android.view.Surface
