cicada-distributed

Cicada Distributed is a framework with the goal of making integration, load, and stress tests less expensive to build. Cicada is designed to manage vast groups of users to test your services while making tests easier to build and understand. To get started, install Cicada through pip:

pip install cicadad

Example

Create a file called test.py with the following:

from cicadad.core.decorators import scenario
from cicadad.core.engine import Engine

engine = Engine()


@scenario(engine)
def my_first_test(context):
    # Results of previously run scenarios get passed in as context

    # Write the body of your test here
    assert 2 + 2 == 4

    # Anything returned gets saved as a user output
    return "Passed!"


if __name__ == "__main__":
    engine.start()

Next, run the test:

cicada-distributed run

You should see Cicada run the test and print something like this in the console:

========================= Test Complete =========================

Passed:

* my_first_test

====================== 1 passed, 0 failed =======================

--------------------- my_first_test: Passed ---------------------

Example with Docker

To create a test and Dockerfile, create a directory and initialize the test scripts:

mkdir example-tests
cicada-distributed init ./example-tests

You should see a couple of files:

- example-tests
  - test.py
  - Dockerfile

Before running tests, you must start a local backend:

cicada-distributed start-cluster

When you run the command cicada-distributed run --mode=DOCKER, Cicada will build an image for the test and start a test runner. You should see the test runner create a container for the test, scenario, and users when you run docker ps.

Once tests are complete, stop the cluster:

cicada-distributed stop-cluster
