locust:tldr:4c299
This command is used to start a Locust load testing tool in the command-line interface. Let's break down each argument:
-
locust
: The keywordlocust
is the command to start the Locust load testing tool. -
--no-web
: This flag is used to run Locust without the web interface. It means that the test will be executed in the command-line interface without opening the web UI for monitoring. -
--clients=${100}
: This argument specifies the number of virtual users (clients) that will be simulated during the load test. In this case, it sets the number of clients to 100. -
--hatch-rate=${1}
: This parameter defines the rate at which new clients are spawned per second. It sets the hatch rate to 1 client per second. That means a new client will be added every second until the total number of clients mentioned in the previous argument is reached. -
--host=${http:--example-com}
: This parameter specifies the base URL or host of the target application to be tested. In this case, the host is set tohttp://example.com
. By providing this argument, Locust will direct the simulated users to this host for load testing purposes.
Note that ${}
is used in the command to denote variable substitution, but it appears to be misplaced in this command. Typically, the ${}
syntax is used in shell scripting or configuration files to substitute the values of predefined or user-defined variables.
