robotframework-env-manage-library 0.1.0

Robot Framework library to override test variables from .env files

EnvManageLibrary

Robot Framework keyword library that overrides test variables with values from .env files.

Variables loaded via Robot Framework's Variables directive (from YAML files) are automatically matched against .env entries and overridden at test-case scope.

Installation

Option 1: From PyPI

pip install robotframework-env-manage-library

Option 2: From local .whl / .tar.gz file

pip install robotframework_env_manage_library-0.1.0-py3-none-any.whl

Option 3: From local packages directory (offline)

pip install --no-index --find-links=./packages robotframework-env-manage-library

.env Naming Convention

The dot (.) separator distinguishes nested dict keys from flat variable names containing underscores.

.env Key	RF Variable	Type
USER=value	${user}	Flat
DB_HOST=value	${db_host}	Flat
AUTHEN.USER=value	${authen}[user]	Nested dict
DB.CONN.HOST=value	${db}[conn][host]	Deep nested dict

Usage

YAML data files

# data/credentials.yaml
user: testuser
pass: "default_pass"

# data/config.yaml
db:
  host: localhost
  port: "5432"

.env file

# Flat overrides
USER=admin
PASS=S3cretK3y!

# Nested dict overrides (use dot separator)
DB.HOST=prod-db.example.com
DB.PORT=5433

Robot Framework test

*** Settings ***
Library    EnvManageLibrary
Variables  ${CURDIR}/data/credentials.yaml
Variables  ${CURDIR}/data/config.yaml

*** Test Cases ***
Verify Credentials Override
    Override Variables From Env    path/to/.env
    Should Be Equal    ${user}    admin
    Should Be Equal    ${pass}    S3cretK3y!

Verify Config Override
    Override Variables From Env    path/to/.env
    Should Be Equal    ${db}[host]    prod-db.example.com
    Should Be Equal    ${db}[port]    5433

Values Reset Between Tests
    # No override called - original YAML values are intact
    Should Be Equal    ${user}    testuser
    Should Be Equal    ${db}[host]    localhost

How It Works

1. Robot Framework loads YAML files via Variables, creating RF variables
2. Override Variables From Env parses the .env file
3. For each RF variable, it checks for a matching .env key:
   • Flat string variables: YAML key user matches env key USER
   • Dict variables: YAML key db with child host matches env key DB.HOST
4. Matched values are overridden using Set Test Variable (scoped to current test only)
5. Original YAML values remain intact for other test cases

Key Behaviors

• Override scope is per test case - original values reset between tests
• If .env file doesn't exist, all variables keep their YAML values
• Case insensitive - YAML user matches env USER
• Flat keys with underscores (DB_HOST) only override flat RF variables (${db_host}), not nested dicts
• Dict values are deep-copied before override to prevent mutation

Development

git clone https://github.com/Non-Spk/robotframework-env-manage-library.git
cd robotframework-env-manage-library
python -m venv venv

# Windows
venv\Scripts\pip install -e ".[dev]"
venv\Scripts\pytest -v

# macOS / Linux
source venv/bin/activate
pip install -e ".[dev]"
pytest -v

Building

pip install build
python -m build

This produces dist/robotframework_env_manage-0.1.0-py3-none-any.whl and dist/robotframework_env_manage-0.1.0.tar.gz.
