Hi,

i try to run tests with no interaction so i try to use -s option but it does nothing (no errors too).

Example without -s :

> [root@ns226456 bin]#./gatling.sh
> 
> GATLING\_HOME is set to /usr/local/gatling
> 
> #logback.classic pattern: %d{HH:mm:ss.SSS} [%-5level] %logger{15} - %msg%n%rEx
> 
> Collecting simulations…
> 
> Choose a simulation number:
> 
> [0] advanced.AdvancedExampleSimulation
> 
> [1] basic.BasicExampleSimulation
> 
> [2] staging.Hits900K
> 
> [3] staging.Hits750K
> 
> [4] staging.Hits600K
> 
> [5] staging.Hits450K

And with -s :

> [root@ns226456 bin]# ./gatling.sh --simulations “staging.Hits450K”  
> GATLING\_HOME is set to /usr/local/gatling  
> #logback.classic pattern: %d{HH:mm:ss.SSS} [%-5level] %logger{15} - %msg%n%rEx  
> Collecting simulations…  
> [root@ns226456 bin]#

What am I doing wrong ?

Regards

This is strange, I didn’t test already, but reading the code, I can’t understand what is the problem. It _should_ work x)

Don’t know if Stéphane will look at it first, but I’m trying to test now 🙂

Tested with 1.2.0-SNAPSHOT on windows (cmd) and with archetype. Couldn’t reproduce bug 😕

I’ll try to get 1.1.6 and test with it 😉

Hi again.

I just tested 1.1.6 and the -s or --simulations switch worked fine for me.

I can’t reproduce the bug :-\

Cheers,  
Romain

Hi François,

What’s your OS? Is it Windows?

no pro  
I’ll have a look and add some logs to make it clearer. I’ll have a look at the docs too.

Have a nice week-end!  
See you,

BTW, removing the samples (basic and advanced) will decrease your start up time as Gatling won’t have to compile them.
