locust

Load-testing tool to determine number of concurrent users a system can handle. More information: https://locust.io.

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

locust --host={{http://example.com}}

• Use a different test file:

locust --locustfile={{test_file.py}} --host={{http://example.com}}

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

locust --no-web --clients={{100}} --hatch-rate={{1}} --host={{http://example.com}}

• Start Locust in master mode:

locust --master --host={{http://example.com}}

• Connect Locust slave to master:

locust --slave --host={{http://example.com}}

• Connect Locust slave to master on a different machine:

locust --slave --master-host={{master_hostname}} --host={{http://example.com}}
