### Examples of context.get_url() Usage in Behave Django

Source: https://github.com/behave/behave-django/blob/main/docs/webbrowser.md

Illustrates various ways to use the `context.get_url()` helper function in a Behave-Django environment. This function simplifies constructing URLs by handling absolute paths, reversing Django view names with arguments, and resolving URLs from model instances.

```python
# Get context.base_url
context.get_url()
# Get context.base_url + '/absolute/url/here'
context.get_url('/absolute/url/here')
# Get context.base_url + reverse('view-name')
context.get_url('view-name')
# Get context.base_url + reverse('view-name', 'with args', and='kwargs')
context.get_url('view-name', 'with args', and='kwargs')
# Get context.base_url + model_instance.get_absolute_url()
context.get_url(model_instance)
```

--------------------------------

### Django Test Client: HTTP Requests

Source: https://context7.com/behave/behave-django/llms.txt

Utilize Django's test client via `context.test.client` to simulate HTTP GET, POST, and other requests. This allows for testing views and request handling without a full browser. It integrates with Behave steps for assertion.

```python
from behave import given, when, then
from http import HTTPStatus

@when('I visit "{url}"')
def visit_url(context, url):
    # Make GET request using Django test client
    context.response = context.test.client.get(url)

@when('I submit a login form with username "{username}" and password "{password}"')
def submit_login(context, username, password):
    # Make POST request with form data
    context.response = context.test.client.post(
        '/login/',
        data={'username': username, 'password': password},
        follow=True  # Follow redirects
    )

@when('I submit JSON data to the API')
def submit_api_data(context):
    # Make POST request with JSON content
    import json
    context.response = context.test.client.post(
        '/api/users/',
        data=json.dumps({'name': 'John Doe', 'email': 'john@example.com'},
        content_type='application/json'
    )

@then('I should see "{text}" on the page')
def check_text_presence(context, text):
    # Use Django's test assertions
    context.test.assertContains(context.response, text)

@then('the response should be successful')
def check_success(context):
    assert context.response.status_code == HTTPStatus.OK

@then('I should be redirected to "{url}"')
def check_redirect(context, url):
    context.test.assertRedirects(context.response, url)
```

--------------------------------

### Behave Configuration for Django Projects (pyproject.toml)

Source: https://context7.com/behave/behave-django/llms.txt

Defines project-level Behave settings within a Django project using pyproject.toml. This includes configuring JUnit XML output, feature file paths, display options for skipped tests, output formats, tag filtering, logging levels, and snippet generation for undefined steps. An example feature file demonstrates usage.

```toml
[tool.behave]
# Enable JUnit XML output
junit = true
junit_directory = "tests/reports"

# Feature file paths
paths = [
    "tests/features",
    "app/features"
]

# Show skipped tests
show_skipped = false

# Output format
format = ["pretty", "json"]

# Tags to include/exclude
tags = ["-wip", "-slow"]

# Logging
logging_level = "INFO"
logging_format = "% (levelname)s - % (message)s"

# Stop on first failure
stop = false

# Show snippets for undefined steps
snippets = true

# Example feature file: features/shopping.feature
# Feature: Shopping Cart
#   Scenario: Add item to cart
#     Given I am logged in as "customer@example.com"
#     When I add product "Laptop" to my cart
#     Then my cart should contain 1 item
#     And the cart total should be "$999.99"
```

--------------------------------

### Reload Django modules for accurate coverage

Source: https://github.com/behave/behave-django/blob/main/docs/testcoverage.md

Reload Django application modules to ensure accurate test coverage measurement, as module loading might occur before coverage starts.

```python
import inspect
import importlib

def reload_modules():
    import your_app1
    import your_app2

    for app in [your_app1, your_app2]:
        members = inspect.getmembers(app)
        modules = map(
            lambda keyval: keyval[1],
            filter(lambda keyval: inspect.ismodule(keyval[1]), members),
        )
        for module in modules:
            try:
                importlib.reload(module)
            except:
                continue
```

--------------------------------

### Execute Behave Tests with Django Management Command

Source: https://context7.com/behave/behave-django/llms.txt

The `python manage.py behave` command executes Behave BDD tests within a Django environment. It automatically handles test database setup and teardown, and supports various options for filtering tests, controlling database behavior, and modifying test execution.

```bash
python manage.py behave

# Run specific feature file
python manage.py behave features/user_login.feature

# Run with specific line number
python manage.py behave features/user_login.feature:42

# Use simple test runner (faster, no browser automation)
python manage.py behave --simple

# Keep test database between runs
python manage.py behave --keepdb

# Use existing database (no test db creation)
python manage.py behave --use-existing-database

# Stop on first failure
python manage.py behave --failfast

# Pass behave-specific options with --behave prefix
python manage.py behave --behave-format pretty --behave-no-capture
```

--------------------------------

### Configure Fixtures and DB Settings in environment.py

Source: https://context7.com/behave/behave-django/llms.txt

Behave's `environment.py` file allows global configuration of fixtures and database settings for Behave-Django tests. Hooks like `before_all`, `before_feature`, and `before_scenario` can be used to dynamically load fixtures and manage database contexts based on test scope or tags.

```python
# features/environment.py

def before_all(context):
    # Load fixtures for all scenarios
    context.fixtures = ['base_data.json']

def before_feature(context, feature):
    # Load fixtures per feature
    if feature.name == 'User Authentication':
        context.fixtures = ['users.json', 'permissions.json']
    elif feature.name == 'Shopping Cart':
        context.fixtures = ['users.json', 'products.json', 'cart.json']

def before_scenario(context, scenario):
    # Load fixtures per scenario with conditional logic
    if 'checkout' in scenario.tags:
        context.fixtures = ['users.json', 'products.json', 'cart.json', 'payment_methods.json']
        context.databases = '__all__'  # Load fixtures to all databases
    elif 'admin' in scenario.tags:
        context.fixtures = ['admin_users.json']

    # Reset sequences to ensure predictable IDs
    context.reset_sequences = True
```

--------------------------------

### Visit Page using Splinter and context.get_url()

Source: https://github.com/behave/behave-django/blob/main/docs/webbrowser.md

This snippet demonstrates how to use the Splinter library within a Behave step to visit a specified page. It utilizes the `context.get_url()` helper function to construct the full URL for the page, abstracting away the base URL and potential URL reversing logic.

```python
from behave import *

@when('I visit "{page}"')
def visit(context, page):
    context.browser.visit(context.get_url(page))
```

--------------------------------

### Run behave tests with tags

Source: https://github.com/behave/behave-django/blob/main/docs/configuration.md

Demonstrates how to run behave tests using the Django management command with specific tags for filtering tests.

```console
python manage.py behave --tags @wip
```

--------------------------------

### Visit URL using Django Test Client in Behave

Source: https://github.com/behave/behave-django/blob/main/docs/testclient.md

This Python snippet demonstrates how to use Django's test client within a behave 'when' step to visit a specified URL. It saves the HTTP response to the context for subsequent steps. This requires behave-django to be configured.

```python
from behave import when

@when('I visit "{url}"')
def visit(context, url):
    # save response in context for next step
    context.response = context.test.client.get(url)
```

--------------------------------

### Load Fixtures Globally in environment.py

Source: https://github.com/behave/behave-django/blob/main/docs/fixtures.md

Loads fixtures before all scenarios in a feature file. This is useful for setting up common data required by all tests. The fixtures are specified as a list of filenames in `context.fixtures`.

```python
def before_all(context):
    context.fixtures = ['user-data.json']
```

--------------------------------

### Load Fixtures Per Scenario in environment.py

Source: https://github.com/behave/behave-django/blob/main/docs/fixtures.md

Loads fixtures dynamically based on the scenario name. This allows different scenarios to use different sets of fixtures. It also includes logic to reset fixtures to an empty list if specific fixtures are not needed for a given scenario, preventing unwanted fixture carry-over. This functionality is automatically handled in behave-django 2.0.0 and later.

```python
def before_scenario(context, scenario):
    if scenario.name == 'User login with valid credentials':
        context.fixtures = ['user-data.json']
    elif scenario.name == 'Check out cart':
        context.fixtures = ['user-data.json', 'store.json', 'cart.json']
    else:
        # Resetting fixtures, otherwise previously set fixtures carry
        # over to subsequent scenarios.
        context.fixtures = []
```

--------------------------------

### Load Fixtures Per Feature in environment.py

Source: https://github.com/behave/behave-django/blob/main/docs/fixtures.md

Loads fixtures before all scenarios within a specific feature file. This approach is useful when a set of fixtures is required for an entire feature but not necessarily for all features in the project. It also includes resetting fixtures for subsequent features. Note: Automatic reset is handled in behave-django 2.0.0+.

```python
def before_feature(context, feature):
    if feature.name == 'Login':
        context.fixtures = ['user-data.json']
        # This works because behave will use the same context for
        # everything below Feature. (Scenarios, Outlines, Backgrounds)
    else:
        # Resetting fixtures, otherwise previously set fixtures carry
        # over to subsequent features.
        context.fixtures = []
```

--------------------------------

### Run behave tests with coverage CLI

Source: https://github.com/behave/behave-django/blob/main/docs/testcoverage.md

Execute behave tests using the `coverage run` command instead of the standard `manage.py` to automatically measure code coverage.

```bash
coverage run manage.py behave
```

--------------------------------

### Configure feature paths using pyproject.toml

Source: https://github.com/behave/behave-django/blob/main/docs/configuration.md

Shows how to specify custom directories for feature files in a Django project using the `pyproject.toml` configuration file. This allows behave to discover feature files from non-default locations.

```toml
[tool.behave]
paths = [
    "my_project/apps/accounts/features/",
    "my_project/apps/polls/features/",
]
```

--------------------------------

### Load Fixtures Across All Databases in behave-django

Source: https://github.com/behave/behave-django/blob/main/docs/fixtures.md

Configures behave-django to load fixtures into all configured databases instead of just the 'default' one. This is necessary for tests that rely on data consistency across multiple databases. The `context.databases = '__all__'` setting should be placed within the `before_scenario` hook.

```python
def before_scenario(context, scenario):
    context.databases = '__all__'
```

--------------------------------

### Behave Navigation Steps for Django

Source: https://context7.com/behave/behave-django/llms.txt

Defines Behave step functions for navigating through a Django application. These steps interact with page objects to perform actions like visiting pages, clicking links, and verifying page elements. Dependencies include 'behave' and page object definitions.

```python
from behave import given, when, then
from pageobjects.pages import HomePage, LoginPage, UserProfilePage

@given('I am on the home page')
def visit_home(context):
    context.current_page = HomePage(context)
    assert context.current_page.response.status_code == 200

@when('I click the login link')
def click_login(context):
    # Get link element and click it
    login_link = context.current_page.get_link('login_link')
    context.current_page = login_link.click()
    assert context.current_page.response.status_code == 200

@then('I should be on the login page')
def verify_login_page(context):
    expected_page = LoginPage(context)
    assert expected_page == context.current_page

@then('I should see the page title "{title}"')
def verify_title(context, title):
    title_element = context.current_page.get_element('title')
    assert title_element.text == title

@then('I should see {count:d} navigation links')
def verify_nav_links(context, count):
    nav_links = context.current_page.get_elements('nav_links')
    assert len(nav_links) == count
```

--------------------------------

### Behave Django Assertions with context.test.assert*

Source: https://context7.com/behave/behave-django/llms.txt

Demonstrates how to use Django's built-in assertion methods within Behave step definitions for more detailed testing of responses and database states. These assertions include checking response content, redirects, status codes, template usage, form errors, and database record counts.

```python
from behave import given, when, then

@then('the response should contain "{text}"')
def check_contains(context, text):
    context.test.assertContains(context.response, text)

@then('the response should not contain "{text}"')
def check_not_contains(context, text):
    context.test.assertNotContains(context.response, text)

@then('the response should contain "{text}" exactly {count:d} times')
def check_contains_count(context, text, count):
    context.test.assertContains(context.response, text, count=count)

@then('I should be redirected to "{url}"')
def check_redirect(context, url):
    context.test.assertRedirects(context.response, url)

@then('the response should have status code {code:d}')
def check_status_code(context, code):
    context.test.assertEqual(context.response.status_code, code)

@then('the template "{template}" should be used')
def check_template(context, template):
    context.test.assertTemplateUsed(context.response, template)

@then('the form should have errors')
def check_form_errors(context):
    context.test.assertFormError(
        context.response,
        'form',
        'email',
        'Enter a valid email address.'
    )

@then('the user should be in the database')
def check_user_exists(context):
    from myapp.models import User
    context.test.assertTrue(
        User.objects.filter(username='testuser').exists()
    )

@then('exactly {count:d} orders should exist')
def check_order_count(context, count):
    from myapp.models import Order
    context.test.assertEqual(Order.objects.count(), count)
```

--------------------------------

### Serve coverage report

Source: https://github.com/behave/behave-django/blob/main/docs/testcoverage.md

Serve the generated HTML coverage report using Python's built-in HTTP server, making it accessible via a web browser.

```bash
python -m http.server --directory ./cov
```

--------------------------------

### URL Helper: Generate Django URLs

Source: https://context7.com/behave/behave-django/llms.txt

The `context.get_url()` helper generates full URLs for live server testing or resolves Django URL patterns. It supports URL names, parameters, model instances with `get_absolute_url`, or direct paths.

```python
from behave import given, when, then

@when('I visit the home page')
def visit_home(context):
    # Get full URL including base_url (for live server testing)
    url = context.get_url('home')  # Uses Django's URL name
    context.response = context.test.client.get(url)

@when('I visit the user profile for user {user_id}')
def visit_profile(context, user_id):
    # Get URL with parameters
    url = context.get_url('user_profile', user_id=user_id)
    context.response = context.test.client.get(url)

@when('I visit the product detail page')
def visit_product(context):
    # Get URL from model instance (requires get_absolute_url)
    from myapp.models import Product
    product = Product.objects.first()
    url = context.get_url(product)
    context.response = context.test.client.get(url)

@when('I visit "{path}"')
def visit_path(context, path):
    # Get URL with just a path
    url = context.get_url(path)
    context.response = context.test.client.get(url)

# Access base_url directly (for Selenium or other browser automation)
@given('the application is running')
def check_app_running(context):
    # context.base_url contains the live server URL
    assert context.base_url.startswith('http://')
```

--------------------------------

### Behave Test Runners Configuration

Source: https://context7.com/behave/behave-django/llms.txt

Provides configurations for different Behave test runners in Django projects, allowing customization of test execution. Options include default runners, simple runners for speed, using existing databases, and custom runner implementations. The settings are configured via command-line arguments or Django's settings.py.

```bash
# Use default runner (full features with live server)
python manage.py behave

# Use simple runner (faster, no browser automation, transaction rollback)
python manage.py behave --simple

# Use existing database (no test db creation, for dry runs)
python manage.py behave --use-existing-database

# Custom runner in command
python manage.py behave --runner myapp.testing.CustomTestRunner
```

```python
# settings.py - Configure custom runner
BEHAVE_RUNNER = 'behave_django.runner.BehaviorDrivenTestRunner'

# Custom runner implementation
from behave_django.runner import BehaviorDrivenTestRunner

class CustomTestRunner(BehaviorDrivenTestRunner):
    def setup_test_environment(self):
        super().setup_test_environment()
        # Custom setup logic
        import os
        os.environ['CUSTOM_TEST_VAR'] = 'test_value'

    def setup_databases(self, **kwargs):
        # Custom database setup
        config = super().setup_databases(**kwargs)
        # Additional database configuration
        return config
```

--------------------------------

### Assert Content using Django Test Client in Behave

Source: https://github.com/behave/behave-django/blob/main/docs/testclient.md

This Python snippet illustrates how to use Django's assertion library within a behave 'then' step to verify if specific text is present in the response. It compares the expected text with the content of the response saved in the context from a previous 'when' step. This relies on the response object being available in the context.

```python
from behave import then

@then('I should see "{text}"')
def visit(context, text):
    # compare with response from ``when`` step
    response = context.response
    context.test.assertContains(response, text)
```

--------------------------------

### Use Page Objects in Behave Step Definitions (Python)

Source: https://github.com/behave/behave-django/blob/main/docs/pageobject.md

This Python code demonstrates how to use the defined Page Objects within behave step definitions. It shows how to instantiate page objects, interact with elements like links, and assert the status of page loads. This integrates the Page Object pattern into the behavior-driven development workflow.

```python
from pageobjects.pages import About, Welcome

@given('I am on the Welcome page')
def step_impl(context):
    context.welcome_page = Welcome(context)
    assert context.welcome_page.response.status_code == 200

@when('I click on the "About" link')
def step_impl(context):
    context.target_page = \
        context.welcome_page.get_link('about').click()
    assert context.target_page.response.status_code == 200

@then('The About page is loaded')
def step_impl(context):
    assert About(context) == context.target_page
```

### Display coverage report

Source: https://github.com/behave/behave-django/blob/main/docs/testcoverage.md

Generate and display a coverage report in the terminal, highlighting lines of code that are not covered by tests.

```bash
coverage report --show-missing
```

### Load Fixtures using Decorator in behave-django

Source: https://github.com/behave/behave-django/blob/main/docs/fixtures.md

Applies Django fixtures to a step implementation using a decorator. The decorator ensures fixtures are loaded before the scenario runs, keeping fixture definitions close to the relevant steps. Fixtures specified this way apply to all steps within the same scenario.

```python
from behave_django.decorators import fixtures

@fixtures('users.json')
@when('someone does something')
def step_impl(context):
    pass
```

### PageObject Pattern: Headless HTML Testing

Source: https://context7.com/behave/behave-django/llms.txt

Implement the PageObject pattern using `behave_django.pageobject` for structured testing of HTML content without a browser. Define pages with `Element` and `Link` objects, mapping them to CSS selectors for BeautifulSoup parsing.

```python
# features/steps/pageobjects/pages.py
from behave_django.pageobject import PageObject, Element, Link

class HomePage(PageObject):
    page = 'home'  # Django URL name
    elements = {
        'title': Element(css='h1.page-title'),
        'nav_links': Element(css='nav a'),
        'login_link': Link(css='a[href*="login"]'),
        'footer': Element(css='footer'),
    }

class LoginPage(PageObject):
    page = '/accounts/login/'  # URL path
    elements = {
        'username_field': Element(css='input[name="username"]'),
        'password_field': Element(css='input[name="password"]'),
        'submit_button': Element(css='button[type="submit"]'),
        'error_message': Element(css='.error-message'),
    }

class UserProfilePage(PageObject):
    page = 'user_profile'  # Django URL name
    elements = {
        'username': Element(css='.profile-username'),
        'email': Element(css='.profile-email'),
        'edit_link': Link(css='a.edit-profile'),
    }
```

### Stop coverage measurement and generate report

Source: https://github.com/behave/behave-django/blob/main/docs/testcoverage.md

Stop test coverage measurement in the `after_all` function, save the results, and generate an HTML report. The report is saved to the specified directory.

```python
def after_all(context):
    cov = context.cov
    cov.stop()
    cov.save()
    cov.html_report(directory="./cov")
```

### Load Django Fixtures with @fixtures() Decorator

Source: https://context7.com/behave/behave-django/llms.txt

The `@fixtures()` decorator in behave-django loads Django fixtures for specific test steps or scenarios. This decorator ensures that test data is available before a step function is executed, providing data isolation per scenario. Multiple fixtures can be loaded simultaneously.

```python
from behave import given, when, then
from behave_django.decorators import fixtures

# Load single fixture
@fixtures('users.json')
@given('a user exists in the database')
def step_impl(context):
    # users.json data is loaded before this step
    from myapp.models import User
    user = User.objects.get(username='testuser')
    assert user.is_active

# Load multiple fixtures
@fixtures('users.json', 'products.json', 'orders.json')
@when('the user places an order')
def step_impl(context):
    # All fixtures are loaded before scenario starts
    from myapp.models import User, Product, Order
    user = User.objects.first()
    product = Product.objects.first()
    order = Order.objects.create(user=user, product=product, quantity=1)
    context.order = order

@then('the order should be saved')
def step_impl(context):
    from myapp.models import Order
    assert Order.objects.filter(id=context.order.id).exists()
```

### Create User within Transaction - Python

Source: https://github.com/behave/behave-django/blob/main/docs/isolation.md

This snippet demonstrates how to create a user within a database transaction that is isolated to a single scenario. The created user will not persist to subsequent scenarios, ensuring test isolation. This relies on the default transaction handling provided by behave-django.

```python
from django.contrib.auth.models import User

@given('user "{username}" exists')
def create_user(context, username):
    # This won't be here for the next scenario
    User.objects.create_user(username=username, password='correcthorsebatterystaple')
```

### Define Page Objects in Python

Source: https://github.com/behave/behave-django/blob/main/docs/pageobject.md

This Python code defines page objects using behave-django's PageObject class. It specifies the page associated with the object and defines elements, such as links, using CSS selectors. This allows for a structured way to interact with web page elements.

```python
from behave_django.pageobject import PageObject, Link

class Welcome(PageObject):
    page = 'home'  # view name, model or URL path
    elements = {
        'about': Link(css='footer a[role=about]'),
    }

class About(PageObject):
    page = 'about'
```
