run_tests.py output with errors even when the test is OK
When we run the command that runs all the tests
python3 tests/run_tests.py
we get the following output
python3 tests/run_tests.py
......usage: run_tests.py [-h] [--es_timeout ES_TIMEOUT] [--insecure] es_host {index,alias} ...
run_tests.py: error: argument --es_timeout: invalid int value: 'pepe'
.....
----------------------------------------------------------------------
Ran 11 tests in 0.062s
OK
it seems an error but it is not an error because the result of all the tests is OK.
We have to remove both outputs (usage and run_test.py error) to provide a clean test output
