2
3	## Core Patterns
4
5	### Feature File (features/login.feature)
6
7	```gherkin
8	Feature: User Login
9	As a user I want to log in
10
11	Scenario: Successful login
12	Given I am on "/login"
13	When I fill in "email" with "user@test.com"
14	And I fill in "password" with "password123"
15	And I press "Login"
16	Then I should see "Dashboard"
17	And I should be on "/dashboard"
18
19	Scenario: Invalid credentials
20	Given I am on "/login"
21	When I fill in "email" with "wrong@test.com"
22	And I fill in "password" with "wrong"
23	And I press "Login"
24	Then I should see "Invalid credentials"
25	```
26
27	### Custom Context (features/bootstrap/LoginContext.php)
28
29	```php
30	<?php
31	use Behat\MinkExtension\Context\MinkContext;
32	use Behat\Behat\Context\Context;
33
34	class LoginContext extends MinkContext implements Context
35	{
36	/**
37	* @When I login as :email with password :password
38	*/
39	public function iLoginAs(string $email, string $password): void
40	{
41	$this->visit('/login');
42	$this->fillField('email', $email);
43	$this->fillField('password', $password);
44	$this->pressButton('Login');
45	}
46
47	/**
48	* @Then I should see the dashboard
49	*/
50	public function iShouldSeeTheDashboard(): void
51	{
52	$this->assertSession()->addressEquals('/dashboard');
53	$this->assertSession()->pageTextContains('Welcome');
54	}
55
56	/**
57	* @Then the response time should be under :ms milliseconds
58	*/
59	public function responseUnder(int $ms): void
60	{
61	// Custom performance assertion
62	}
63	}
64	```
65
66	### Built-in MinkContext Steps
67
68	```gherkin
69	# Navigation
70	Given I am on "/path"
71	When I go to "/path"
72	When I reload the page
73
74	# Forms
75	When I fill in "field" with "value"
76	When I select "option" from "select"
77	When I check "checkbox"
78	When I uncheck "checkbox"
79	When I press "button"
80	When I attach the file "path" to "field"
81
82	# Assertions
83	Then I should see "text"
84	Then I should not see "text"
85	Then I should be on "/path"
86	Then the response status code should be 200
87	Then the "field" field should contain "value"
88	Then I should see an "css-selector" element
89	Then print current URL
90	```
