Autodiscovery and autocreate tox testenv to aws lambda functions

---

This Pytest plugin was generated with Cookiecutter along with @obestwalter's Cookiecutter-tox-plugin template.

This project is not yet ready for production.

Features

Autodiscovery and autocreate tox testenv to aws lambda function.

TODO:

• rewrite code when tox api is more flexible: https://mail.python.org/mm3/archives/list/[e-mail]/thread/2B2GXTFWCE6FYMVCMBMKAOQAXEOGXEWR/
• Write tests

Requirements

• Python >= 3.6, tox >= 3.3.0

Installation

You can install tox-lambda-autodiscovery via pip from PyPI:

$ pip install tox-lambda-autodiscovery

or directly from github:

$ pip install -e git+https://github.com/luzfcb/tox-lambda-autodiscovery@master#egg=tox-lambda-autodiscovery

Usage

Add a new section named [testenv:lambdaautodiscovery] on tox.ini.

The plugin is active only when the section [testenv:lambdaautodiscovery] exists.

Configuration options for [testenv:lambdaautodiscovery]

search_dirs

A list of directories that the plugin uses as autodiscover. The default value is {toxinidir}.

Example

Having a list of directories, with subdirectories, which contains a file requirements.txt, and a python file started with test on the same directory level:

project:
       README.md
       backend1/
              serverless.yml
              package.json
              node_modules/
              functionCreateRole/
                   create_role.py
                   requirements.txt
                   test_create_role.py
       backend2/
              serverless.yml
              package.json
              node_modules/
              functionCreateUser/
                   create_user.py
                   requirements.txt
                   test_create_user.py

The search_base_dirs looks like the following:

search_dirs = backend1
              backend2

ignored_dirs

Directories that the plugin should ignore in autodiscovery.

Example

ignored_dirs = .serverless
               .vscode

The directories with the following names are ignored by default:

.tox
__pycache__
eggs/
.eggs/
node_modules

If you want to override the default ignored directories names, use the option default_ignored_dir_names.

the commands_workaround is a way to customize tox commands

eg.:

commands_workaround = {posargs:pytest} --cov={current_toxenv_lambda_dir} --basetemp={envtmpdir}

is ugly, but, tox 3.3.0 api has no simple way to defer processing of commands

The PYTHONPATH can be customized by setting

setenv =
    PYTHONPATH = {toxinidir}/backend/

Full sample config:

the following directories structure:

(myproject) fabio@luzfcb:~/projects$ tree myproject -L 2

ignored_dirs = .serverless

search_dirs = backend

setenv =
