I am trying to do a charge test with RSelenium on my deployed Shiny application. Several users connect to the adress and do random tasks at the same time.
I have searched doParallel but the number of concurrent process is limited by numbers of core - 1.
I have tried the following command line to start N process in the background at the same time. A number is given as parameter to define browser's port. It is working until 3 process but over some process fail and are not always the same.
'start /b "P1" Rscript R/run_tests.R 1 &
start /b "P2" Rscript R/run_tests.R 2 &
start /b "P3" Rscript R/run_tests.R 3 &
start /b "P4" Rscript R/run_tests.R 4 &
start /b "P5" Rscript R/run_tests.R 5'run_tests open a new web driver and navigate on the webpage.
A solution would be to ask several colleagues to run this code for 3 process but I would like to reach 20 users.
Answer on Windows will be more appreciated but Linux is not a problem. Do you know the proper way to do it with RSelenium ? Thanks a lot for any clue.
