This tool was released lately.
If you upload a ZIP of your LoadRunner script, it will convert it to JMeter or Selenium.
It might not be 100%, but it will tell you what it couldn't convert and save you a lot of troubles.
The fastest and the easiest way is just recording them.
Start JMeter's HTTP(S) Test Script Recorder
Configure VuGen to use JMeter as a proxy
Run your test with 1 virtual user and 1 iteration. While your test is running JMeter will create the relevant HTTP Request samplers
When execution is finished you will have JMeter script "skeleton"
See How to ...
Given 4000 requests per hour and the fact the application will be used only internally (response time is not crucial) I don't think you have to do any load testing as 4000 requests per hour is just 1.11 requests per second.
Normally performance testing is done as follows:
Load Testing - put your application under anticipated load (in your case 150 ...
The best option will be deploying some free and open source application like Drupal, Magento, Moodle, etc. somewhere to your intranet. This way you will be able not only to get hands on experience with creating scripts and setting up load patterns but will also be able to see the impact of your load test by monitoring baseline server-side health metrics. ...
Let’s say that the action under test takes one second. Then one user doing that 1k times would spread out the test over 1k seconds. 1k users doing it once would try and the same work in one second I.e. at the same time.
So while they do basically the same amount of work, since the time scales are significantly different, then the load is significantly ...
In most cases, whether LoadRunner is simulating 1 user and having them do 1k actions at the same time or 1k users and having them do just 1 thing, won’t make a difference. Because generally the question of scale is really about number of simultaneous connections. But it can make a difference due to caching and state changes.
Simple example, suppose you ...
JMeter acts as follows:
JMeter starts defined number of threads during ramp-up period
Threads start executing samplers upside down (or according to Logic Controllers)
When thread doesn't have any more samplers to execute or loops to iterate - it's being shut down
So if your test is short enough you may easily run into a situation when 1st ...
set ramp up time to zero to start all the thread at same time.
difference in starting time between threads = Ramp up time/ no of threads.
If you have ramp up time = 20 and no of threads = 100
then each thread with start with time gap of 0.2 (20/100) sec from previous thread
There are a number of possibilities:
It may be that the load test is reusing existing connections instead of closing and reopening connections with each request. This would cause the load test to run better than the single user test.
Make sure caching is turned off for the load test. Caching at the DB & web servers as well as the load tool must be ...
In my personal opinions, I have a few points (in strong font.) to add:
The average user load is determined to be 150 users, what is your peak user load?
average hourly page views is determined to be approx 4000/hour, what is your peak page view per hour?
Ramp up 75 users, 2 every 20 seconds and run for 6 hours, by the end of 6 hours, would you have 75 users ...
You should not be trying to "break" the application, the targets of the performance testing could be:
Check whether your application is capable of handling anticipated load, i.e. if you expect 1000 concurrent users you should test if your application can handle 1000 concurrent users providing reasonable response times without any errors. This is called Load ...
That depends on what you are testing. assuming you want to test a servers ability to serve static webpages to different users, having only one user would make no sense. The first iteration might give a reasonable result but further iterations might be much faster because of e.g. caching or not having the overhead of establishing a secure connection.
Here is my project to convert loadrunner http/html scripts to jmeter.
we are working to reduce the manual effort involved in converting the scripts.
Like you have pointed out, there is no debug mode in LoadRunner (as far as I recollect) like you would, in Eclipse IDE.
You will be able to place breakpoints on 'lr_' functions and when the script is run the execution will halt at the breakpoint. This can be used to verify, if the correlations and parameters substitution have occurred correctly up to the ...
Notice, you are violating a lot of testing 101 here. For each step there is an expected result. You are not checking in your test code for the positive, expected step result. Along with that lack of checking, there is no branching of execution when the positive expected result is not achieved. As a result your business process has likely come off the ...
If you have 100 Threads in thread group and Ramp up time as 20, these 100 threads aren't concurrent. To maintain concurrency for 100 threads you have to use either loop counts or Durations (Scheduler in Thread Group).
You may try with the "Ultimate Thread Group" (JMeter plugins) instead of only "Thread group". To check this, you can use "Active Threads Over ...
When you are doing a load test on an application, there is a lot that you have to take into consideration,
CPU utilization over time with consistent load.
RAM utilization over time with consistent load.
Disk I/O utilization over time with consistent load.
Network I/O utilization over time with consistent load.
Not just the server's CPU and RAM but its ...
This is a network constraint over which you may not have any control. Do you know after what time you get this error?
You could play with Timeouts section on HTTP Request Sample and keep it higher than the time which causes timeout error.
Well, this depends on your application.
At a former location there was a database that orders was injected into after initial processing, by injecting into the database directly I was able to make millions of orders in a matter of minutes. This will usually bypass many parts of the system (Payments, Inventory validation etc). If those pieces are not being ...
Your daily routine will be completely dependent on your company and the responsibilities you have in your role. In simple terms below are some of the potential things in the day to day of a (performance) tester
Attend agile ceremonies (standup, look ahead, etc)
Evaluate previous performance reports
Raise any issues and prioritize accordingly
That is a good question!
Controller is showing “average” response time since in online it receives only “aggregated” values from all vusers/hosts.
Controller has no details(per vuser) in “live” mode.
Only after scenario completion, Analysis gather (collate) all the details from all LGs (where they were kept during scenario run) and allow customer analyze ...
