性能测试——压测工具locust——脚本初步简介

locusts脚本，初步简介：

参数：

C:\Users\lenovo>locust --help
Usage: locust [OPTIONS] [UserClass ...]

Common options:
-h, --help show this help message and exit
-f LOCUSTFILE, --locustfile LOCUSTFILE
Python module to import, e.g. '../other_test.py'.
Either a .py file, multiple comma-separated .py files
or a package directory. Defaults to 'locustfile'.
--config CONFIG Config file path
-H HOST, --host HOST Host to load test in the following format:
http://10.21.32.33
-u NUM_USERS, --users NUM_USERS
Peak number of concurrent Locust users. Primarily used
together with --headless or --autostart. Can be
changed during a test by keyboard inputs w, W (spawn
1, 10 users) and s, S (stop 1, 10 users)
-r SPAWN_RATE, --spawn-rate SPAWN_RATE
Rate to spawn users at (users per second). Primarily
used together with --headless or --autostart
-t RUN_TIME, --run-time RUN_TIME
Stop after the specified amount of time, e.g. (300s,
20m, 3h, 1h30m, etc.). Only used together with
--headless or --autostart. Defaults to run forever.
-l, --list Show list of possible User classes and exit

Web UI options:
--web-host WEB_HOST Host to bind the web interface to. Defaults to '*'
(all interfaces)
--web-port WEB_PORT, -P WEB_PORT
Port on which to run web host
--headless Disable the web interface, and start the test
immediately. Use -u and -t to control user count and
run time
--autostart Starts the test immediately (like --headless, but
without disabling the web UI)
--autoquit AUTOQUIT Quits Locust entirely, X seconds after the run is
finished. Only used together with --autostart. The
default is to keep Locust running until you shut it
down using CTRL+C
--web-auth WEB_AUTH Turn on Basic Auth for the web interface. Should be
supplied in the following format: username:password
--tls-cert TLS_CERT Optional path to TLS certificate to use to serve over
HTTPS
--tls-key TLS_KEY Optional path to TLS private key to use to serve over
HTTPS
--class-picker Enable select boxes in the web interface to choose
from all available User classes and Shape classes

Master options:
Options for running a Locust Master node when running Locust distributed. A Master node need Worker nodes that connect to it before it can run load tests.

--master Set locust to run in distributed mode with this
process as master
--master-bind-host MASTER_BIND_HOST
Interfaces (hostname, ip) that locust master should
bind to. Only used when running with --master.
Defaults to * (all available interfaces).
--master-bind-port MASTER_BIND_PORT
Port that locust master should bind to. Only used when
running with --master. Defaults to 5557.
--expect-workers EXPECT_WORKERS
How many workers master should expect to connect
before starting the test (only when
--headless/autostart is used).
--expect-workers-max-wait EXPECT_WORKERS_MAX_WAIT
How long should the master wait for workers to connect
before giving up. Defaults to wait forever

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

--worker Set locust to run in distributed mode with this
process as worker
--master-host MASTER_NODE_HOST
Host or IP address of locust master for distributed
load testing. Only used when running with --worker.
Defaults to 127.0.0.1.
--master-port MASTER_NODE_PORT
The port to connect to that is used by the locust
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:
[CSV_PREFIX]_stats.csv, [CSV_PREFIX]_stats_history.csv
and [CSV_PREFIX]_failures.csv
--csv-full-history Store each stats entry in CSV format to
_stats_history.csv file. You must also specify the '--
csv' argument to enable this.
--print-stats Enable periodic printing of request stats in UI runs
--only-summary Disable periodic printing of request stats during
--headless run
--reset-stats Reset statistics once spawning has been completed.
Should be set on both master and workers when running
in distributed mode
--html HTML_FILE Store HTML report to file path specified
--json Prints the final stats in JSON format to stdout.
Useful for parsing the results in other
programs/scripts. Use together with --headless and
--skip-log for an output only with the json data.

Logging options:
--skip-log-setup Disable Locust's logging setup. Instead, the
configuration is provided by the Locust test or Python
defaults.
--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 stderr

Other options:
--show-task-ratio Print table of the User classes' task execution ratio.
Use this with non-zero --user option if some classes
define non-zero fixed_count attribute.
--show-task-ratio-json
Print json data of the User classes' task execution
ratio. Use this with non-zero --user option if some
classes define non-zero fixed_count attribute.
--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.
--equal-weights Use equally distributed task weights, overriding the
weights specified in the locustfile.
--enable-rebalancing Allow to automatically rebalance users if new workers
are added or removed during a test run.

User classes:
UserClass Optionally specify which User classes that should be
used (available User classes can be listed with -l or
--list). LOCUST_USER_CLASSES environment variable can
also be used to specify User classes
