cicadad 1.4.0

Library for running distributed Cicada tests

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

You will also need to install Docker in order to use Cicada locally. To install Docker, visit https://docs.docker.com/get-docker/.

Example

Before running tests, you must start redis, datastore-client, and the container-service containers. To start the cluster, run:

cicada-distributed start-cluster

To create a simple test, 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

Inside the test.py, there will be a basic test:

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

Cicada will build an image for the test and start a test runner. You should see the test runner collect the scenario and successfully complete.

Finally, stop the cluster:

cicada-distributed stop-cluster
