locust

Load-testing tool to determine number of concurrent users a system can handle. More information: https://docs.locust.io/en/stable/configuration.html#configuration.

• Load-test "example.com" with web interface using locustfile.py:

locust {{[-H|--host]}} {{http://example.com}}

• Use a different test file:

locust {{[-H|--host]}} {{http://example.com}} {{[-f|--locustfile]}} {{test_file.py}}

• Run test without web interface, spawning 1 user a second until there are 100 users:

locust {{[-H|--host]}} {{http://example.com}} --headless {{[-u|--users]}} 100 {{[-r|--spawn-rate]}} 1

• Start Locust in master mode:

locust {{[-H|--host]}} {{http://example.com}} --master

• Connect Locust worker to master:

locust {{[-H|--host]}} {{http://example.com}} --worker

• Connect Locust worker to master on a different machine:

locust {{[-H|--host]}} {{http://example.com}} --worker --master-host {{master_hostname}}
