Running couple of tests in robot framework infinitely - robotframework

Question

How can I run a couple of tests in robot framework infinitely or atleast a large number of times finitely.
Eg:
Test case 1
.
.
.
Test case 2
.
.
.
Test case 3
.
.
.
I want Tests to run in the order 1,2,3,1,2,3... finitely (for a large number) or infinitely.
I know how to do it for a single test. But I want it to come back and do test 1 after test 3. And i want this batch to run in a loop.

Answer 1

It is not possible to create a infinite loop within RF which will run the current file over and over again indefinitely. Instead, you could create a script which points to the RF file, handles the infinity(ness) for you, and then when needed to, kill the process and join all the output.xml's together, creating the mother of all mothers RF reports. Here is a quick example within Python:
import subprocess
import os
import glob
try:
while True:
subprocess.call("robot EnterFileNameHere.robot") # Add any robot options you may want
except KeyboardInterrupt:
total = []
os.chdir("/DirectoryWhich/HasAll/TheXML/Files")
for GrabbedFiles in glob.glob("*.xml"):
total += GrabbedFiles
Converted = " ".join(str(x) for x in total)
subprocess.call("rebot {0}".format(Converted)) # Add any rebot options you may want
Change the directories to match where your files are, and this should infinitely fire off your robot file of choice, constantly creating report files / output files. Once you kill it (with CTRL+C) it will accept that as a KeyboardInterrupt which will then, merge all of the output files for you, and then close the terminal.
The only other way to do this within RF itself is by this answer here but this would only generate a report for you once the loop is completed. I do not know how it would handle report generation if you suddenly killed RF. I presume it wouldn't create any reports at all. So personally, I think this is your best bet.
Any questions let me know.
