pact-state-provider 1.0.9

Installation

1. Install the package:

   pip install pact_state_provider

Client

Entrypoint pact-state-provider:

Usage: pact-state-provider [OPTIONS]

  Start the state provider server on the specified host and port.

Options:
  --base-module TEXT  Module containing the state providers.
  --host TEXT         Host for the endpoint. Default: 127.0.0.1
  --port INTEGER      Port for the endpoint. Default: 1235
  --log-level TEXT    Log Level Name (DEBUG, INFO, ...). Default: INFO
  --help              Show this message and exit.

TL;DR

Example:

$ pact-state-provider --base-module my_provider.states

$ http http://127.0.0.1:1235 consumer=TestConsumer state="user exists" --json
DEBUG: Importing my_provider.states
DEBUG: Getting function "user_exists"
-> "my_provider.states.user_exists('TestConsumer')" is called

Not Long Enough;Will Read

When verifying contracts with Pact a state provider is called for the particular consumer with the state requested. A consumer TestConsumer with a contract starting with given('user exists') requests the configured endpoint with the payload:

{
    'consumer': 'TestConsumer',
    'state': 'user exists'
}

In order to execute the specific provider functions without having to implement a dedicated endpoint on the provider or a dedicated application with provider specific code pact-state-provider provides a simple http server endpoint which calls an existing module function based on the request payload.

In the given example a function called user_exists (invalid characters are translated to underscores) will be executed on the specified base module (--base-module parameter).

This gives the user to maintain the state provider code in the actual provider codebase, but easily have an endpoint to use with pact.

A New Version

1. Cherrypick all wanted commits onto the support branch (f.e. support/1.0)

2. Push the commits

3. Increment the version in setup.py and update the changelog and commit

4. Tag the commit with the new version (f.e. v1.0.8)

5. Push the version commit

Travis will build the new version and upload it to Pypi automatically when finding a tag on the support branch.
