3	## Core Patterns
4
5	### Feature File (features/login.feature)
6
7	```gherkin
8	Feature: User Login
9	As a registered user
10	I want to log into the application
11
12	Background:
13	Given I am on the login page
14
15	Scenario: Successful login
16	When I enter "user@test.com" as email
17	And I enter "password123" as password
18	And I click login
19	Then I should see the dashboard
20	And the welcome message should say "Welcome"
21
22	Scenario: Invalid credentials
23	When I enter "wrong@test.com" as email
24	And I enter "wrong" as password
25	And I click login
26	Then I should see error "Invalid credentials"
27
28	Scenario Outline: Login with various users
29	When I enter "<email>" as email
30	And I enter "<password>" as password
31	And I click login
32	Then I should see "<result>"
33
34	Examples:
35	\| email \| password \| result \|
36	\| admin@test.com \| admin123 \| Dashboard \|
37	\| bad@test.com \| wrong \| Error \|
38	```

73	)
74	assert '/dashboard' in context.browser.current_url
75
76	@then('I should see error "{msg}"')
77	def step_see_error(context, msg):
78	error = WebDriverWait(context.browser, 5).until(
79	EC.visibility_of_element_located((By.CSS_SELECTOR, '.error'))
80	)
81	assert msg in error.text
82	```
83
84	### Environment Hooks (features/environment.py)
85

89	def before_all(context):
90	context.base_url = 'http://localhost:3000'
91
92	def before_scenario(context, scenario):

97	if scenario.status == 'failed':
