Warnings

breaking behavex 4.x may have breaking changes from 3.x. The API for parameterized scenarios changed; check the release notes. ↓

fix Review changelog at https://github.com/behavex/behavex/releases before upgrading.

deprecated Some older behavex-specific step decorators (like @behavex.step) have been deprecated in favor of standard behave decorators. ↓

fix Use @given, @when, @then from `behave` module instead of behavex-specific decorators.

gotcha behavex extends behave but does not replace it. You must still install `behave` as a dependency. ↓

fix Ensure `behave` is in your requirements.txt or installed alongside behavex.

Quickstart

Shows basic behavex test structure using behave syntax. Behavex extends behave with parameterized scenarios; run tests with the `behave` command.

import behavex

# behavex is an extension of behave; it uses same Gherkin syntax
# Example: feature file 'steps/example.feature'
# Feature: Example
#   Scenario: Test addition
#     Given I have 5 and 3
#     When I add them
#     Then the result should be 8

# Steps definition (in steps/example_steps.py)
from behave import given, when, then

@given('I have {a:d} and {b:d}')
def step_impl(context, a, b):
    context.a = a
    context.b = b

@when('I add them')
def step_impl(context):
    context.result = context.a + context.b

@then('the result should be {expected:d}')
def step_impl(context, expected):
    assert context.result == expected, f"Got {context.result}"

# Run with: behave
