You've setup your test and you're ready to go!
Once you've setup and saved all of your test configurations, you can start running it by clicking the 'Play' button at the top of the screen.
You'll then be asked if you're ready to launch the servers. Click Launch Servers to continue.
Now You'll be able to see a progress bar, telling you how much longer you need to wait. Launching servers in the cloud usually takes 2-4 minutes. Tests involving a larger number of servers may take around 10-12 minutes.
If you wish to see the system log you can click on 'Toggle system log'. This shows you everything that is happening from the user perspective and the system perspective - from both the JMeter log and the script log. You can also check the box Alert on a New Message to get notifications with every new action.
There are three checkboxes at the top of the system log: user, system or console. You can keep them all checked and the system log will show you whats going on in all of them at once, review each one individually - or a combination of the three.
You can complete other tasks while the test is running in the background, such as viewing reports - or even configuring and running other tests.
You can wait a few minutes until the test ends or you can stop the test yourself.
If you want to stop the test, just go to the top of the screen and hit the 'stop' icon. You can also find the stop button in the test list on the left of the screen beside the relevant test - for quick access.
Now You'll be asked whether you want to execute a Graceful Shutdown or immediately Terminate the Servers.
We recommend executing a graceful shutdown as it will archive all the JTL files and upload them to the report's folder. If you terminate the servers immediately, you will loose the JTL file of the test and you might defect the report.
