How to let method run in background

Question

I am calling python method from robot keyword. But I do not want robot framework to wait until test is finished because I want to run that method continuously. How to continue running next test case? e.g. I am calling start logs (python method) from robot keyword

def start_logs(self):
    subprocess.call('adb logcat > test.txt', shell=True)

After starting logs I want to run other test cases. But robot framework keeps waiting for above.

Use [`subprocess.Popen`](https://docs.python.org/3/library/subprocess.html#subprocess.Popen) — Colonel Thirty Two, Nov 03 '15 at 00:39

You can do:

def start_logs(self):
    subprocess.Popen(['adb', 'logcat', '>', 'test.txt'])

using subprocess.Popen as Colonel Thirty Two mentioned in the comments.

when I run above rather than writing to file it's just printing adb logcat to console? looks like '>' is not working? – user2661518 Nov 05 '15 at 22:43

There is a Keyword for that! Start Process will call any keyword but will not wait for it to return. Don't forget to add the Process library to your project.

Start Process can not be used with keywords – maiksaray Nov 16 '16 at 14:03
@maiksaray: yes. You use Start Process with a command, not a keyword. – joris255 Jan 24 '17 at 01:04
