JMeter Summary Report % Error

Question

I just develop a web apps, and test it using jmeter. Anyway I'm new in jmeter, still not familiar with it.

All test is good, except there is 100% on % error column. I still wondering what is it based, I test it using browser, it working properly, I'm using 1 instance/ 1 request, still it show 100% error.

What Error % column in Summary Report based on? And how I know what error it found which I don't know? Many thanks.

Answer 1

Add a tree result listener to your test plan and run it with 1 user, you will get more infos on error.

This error tells you either request failed or response failed based on assertion made (text , response code ...)

Answer 2

Seems your test is not running as expected. If you are running against anything that is live the ideal error rates should be 0% or tending to it (unless the application is down or you are testing something negatively).

Answer 3

You can use the "Server Hits per Second", Available in the Plugin Standard Set. http://jmeter-plugins.org/wiki/HitsPerSecond/?utm_source=jmeter&utm_medium=helplink&utm_campaign=HitsPerSecond

Answer 4

I accessed errors by Adding a new 'View Results Tree' listener. There were 2 existing 'View Results Tree' nodes in my Test Plan, but I added the new one this way:

• Right-click 'Test Plan' node
• Add > Listener > View Results Tree

This added a new listener under my 'HTTP(S) Test Script Recorder' node. I then re-ran my test with a large number of users (not 1 user, as the accepted answer suggests), and the errors are then all available under the 'View Results Tree' node.
