appian-locust 2.0.0a8

Tools and functions to make testing Appian with Locust easier

Appian Locust is a wrapper library around Locust for load testing Appian. This library is intended to be used as an alternative to tools such as Jmeter and Load Runner.

Appian Locust capabilities

• Logging in and logging out

• Form interactions (filling/submitting)

• Finding and interacting with basic components on a SAIL interface

• Navigating to records/reports/sites

Disclaimer: This library is continuously evolving. Currently the main focus is supporting essential use-cases. We are happy to accept contributions to further extend functionality, address bug fixes and improve usability. Please see the Contributing section and feel free to reach out.

Quick Start Guide

This is a quick guide to getting up and running with the appian-locust library. You will need Python 3.7+ installed on your machine before proceeding.

Setup

1. Install appian-locust using pip, for more comprehensive projects we recommend using pipenv.

pip install appian-locust

If using pipenv, simply start from the following Pipfile:

[packages]
appian-locust = {version = "*"}

[requires]
python_version = "3.10"

[pipenv]
allow_prereleases = true

2. Configure your test to point at the Appian instance you will be using. You can use example file provided in this repository example_config.json:

• Set host_address to the address of your Appian instance.

• In auth, specify the username and password of the user account to use. Note: This user must be able to access Tempo.

{
    "host_address": "site-name.appiancloud.com",
    "auth": [
        "user.name",
        "password"
    ]
}

3. Run the sample test example_locustfile.py.

locust -f example_locustfile.py -u 1 -t 60 --headless

If everything is set up correctly, you should start to see output from the load test reporting results. This should run for 60 seconds and end with a summary report of the results.

• For more examples of different site interactions, see the example_*.py files included in this repository.

• For more in-depth information about the test library, see the rest of this documentation.

Build from source

Clone the repository:

git clone -o prod [e-mail]:appian-oss/appian-locust.git

Install the library globally:

pip install -e appian-locust

If you’re using a virtualenv or a dependency management tool (e.g. pipenv), you can do the same type of install, but you will want to be in the context of the virtualenv (i.e. source the virtualenv), and you’ll need to pass the path to the repository you cloned.

Note: It’s highly recommended that you use a virtual environment when installing python artifacts. You can follow the instructions here to install virtualenv and pip.

If you have issues installing, make sure you have the proper prerequisites installed for Locust and its dependencies. If you’re having trouble on Windows, check here

Troubleshooting

• “Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known”

  • check that host_address is specified correctly in example_config.json.

• “Login unsuccessful, no multipart cookie found…make sure credentials are correct”

  • check that auth specifies a valid username and password combination for the site you’re testing on in example_config.json.

• “General request and response debugging”

  • Add self.appian.interactor.record_mode = True to your AppianTaskSet subclass. Files will be placed in /record_responses where the runner is executed.
