Dynamic Fixtures Example

This repository contains example code and service templates which utilizes Applatix's dynamic fixtures feature.

Dynamic fixtures can be used in workflow service templates and are defined by adding a fixtures: section in the service template. Dynamic fixtures reference other container service templates through the template: field.

type: service_template
subtype: workflow
name: example-dynamic-fixtures
description: Clone the Applatix/example-dynamic-fixtures repo and run perf tests against database fixtures
fixtures:
  - mongodb:
      template: mongodb
    redisdb:
      template: redis
inputs:
  parameters:
    commit:
      default: "%%session.commit%%"
    repo:
      default: "%%session.repo%%"
    iterations:
      default: 100000
steps:
  - checkout:
      template: axscm-checkout
  - test:
      template: python-dbtest
      parameters:
        checkout: "%%steps.checkout%%"
        redis_ip: "%%fixtures.redisdb.ip%%"
        mongodb_ip: "%%fixtures.mongodb.ip%%"

During execution of the example-dynamic-fixtures workflow, two database container instances, MongoDB and Redis, will be launched for the duration of the workflow. The IP address of the containers can be referenced via the %%fixtures.<fixture_name>.ip%% attribute of the fixtures.

In this example, the Redis IP address and MongoDB IP are passed as input parameters to the python-dbtest service template, which the test can use to perform its tests.

subtype: container
name: python-dbtest
description: Run key/value insertion & retrieval tests against MongoDB and Redis
container:
  image: python:3.5.2
  resources:
    mem_mib: 256
    cpu_cores: 0.1
  command: sh -c "pip install -r /src/requirements.txt && /src/dbtest.py --redis %%redis_ip%% --mongodb %%mongodb_ip%% --iterations %%iterations%%"
inputs:
  parameters:
    checkout:
    redis_ip:
    mongodb_ip:
    iterations:
  artifacts:
  - from: "%%service.checkout.code%%"
    path: "/src"

Upon completion of the workflow, dynamic fixtures are automatically terminated.
