+# Run load test
+
+> Integrated since HttpRunner 3.1.0
+
+With reuse of [`Locust`][Locust], you can run load test without extra work.
+
+```text
+$ locusts -V                                                                 
+locust 1.0.3
+```
+
+For full usage, you can run `locusts -h` to see help, and you will find that it is the same with `locust -h`.
+
+The only difference is the `-f/--locustfile` argument. When you specify `-f` with a YAML/JSON testcase file, it will convert to pytest first and then run load test with HttpRunner's builtin locustfile(httprunner/ext/locust/locustfile.py).

+                        before starting the test (only when --headless used).
+
+Worker options:
+  
+  Options for running a Locust Worker node when running Locust distributed. 
+  Only the LOCUSTFILE (-f option) need to be specified when starting a Worker, since other options such as -u, -r, -t are specified on the Master node.
+

+                        master for distributed load testing. Only used when
+                        running with --worker. Defaults to 5557.
+
+Tag options:
+  Locust tasks can be tagged using the @tag decorator. These options let specify which tasks to include or exclude during a test.
+
+  -T [TAG [TAG ...]], --tags [TAG [TAG ...]]
+                        List of tags to include in the test, so only tasks
+                        with any matching tags will be executed
+  -E [TAG [TAG ...]], --exclude-tags [TAG [TAG ...]]
+                        List of tags to exclude from the test, so only tasks
+                        with no matching tags will be executed
+
+Request statistics options:
+  --csv CSV_PREFIX      Store current request stats to files in CSV format.
+                        Setting this option will generate three files:

+                        in distributed mode
+
+Logging options:
+  --skip-log-setup      Disable Locust's logging setup. Instead, the

+  --loglevel LOGLEVEL, -L LOGLEVEL
+                        Choose between DEBUG/INFO/WARNING/ERROR/CRITICAL.
+                        Default is INFO.
+  --logfile LOGFILE     Path to log file. If not set, log will go to
+                        stdout/stderr
+
+Step load options:
+  --step-load           Enable Step Load mode to monitor how performance
+                        metrics varies when user load increases. Requires
+                        --step-users and --step-time to be specified.
+  --step-users STEP_USERS

+
+Other options:
+  --show-task-ratio     Print table of the User classes' task execution ratio
+  --show-task-ratio-json
+                        Print json data of the User classes' task execution
+                        ratio
+  --version, -V         Show program's version number and exit
+  --exit-code-on-error EXIT_CODE_ON_ERROR
+                        Sets the process exit code to use when a test result
+                        contain any failure or error
+  -s STOP_TIMEOUT, --stop-timeout STOP_TIMEOUT
+                        Number of seconds to wait for a simulated user to
+                        complete any executing task before exiting. Default is
+                        to terminate immediately. This parameter only needs to
+                        be specified for the master process when running
+                        Locust distributed.
+
+User classes:
+  UserClass             Optionally specify which User classes that should be
+                        used (available User classes can be listed with -l or
+                        --list)

+## Client & Server IP:PORT
