locust:tldr:d7a40

The given command is used to run the Locust load testing tool with specific configurations. Let's break down the components of the command:

• locust: This is the command to execute the Locust load testing tool.

• --locustfile=${test_file-py}: This option specifies the Python file containing the Locust test scenarios and configurations. The value ${test_file-py} indicates that the file name can be passed as an argument when running the command. For example, if the test file is named my_test.py, the command would be --locustfile=my_test.py.

• --host=${http:--example-com}: This option defines the base URL of the target application that will be tested. The value ${http:--example-com} suggests that the host can be passed as an argument when executing the command. The default value is http://example.com, but it can be changed by providing a different URL. For instance, --host=http://myapp.com would set the target host to http://myapp.com.

In summary, this command runs the Locust load testing tool, specifies the Python file containing the test scenarios, and sets the target application's base URL.
