2
3	## Core Patterns
4
5	### Basic Test
6
7	```php
8	<?php
9	use PHPUnit\Framework\TestCase;
10
11	class CalculatorTest extends TestCase
12	{
13	private Calculator $calculator;
14
15	protected function setUp(): void
16	{
17	$this->calculator = new Calculator();
18	}
19
20	public function testAddition(): void
21	{
22	$this->assertEquals(5, $this->calculator->add(2, 3));
23	}
24
25	public function testDivideByZero(): void
26	{
27	$this->expectException(\DivisionByZeroError::class);
28	$this->calculator->divide(10, 0);
29	}
30
31	public function testMultipleAssertions(): void
32	{
33	$this->assertSame(4, $this->calculator->add(2, 2));
34	$this->assertSame(0, $this->calculator->subtract(2, 2));
35	$this->assertSame(6, $this->calculator->multiply(2, 3));
36	}
37	}
38	```
39
40	### Data Providers
41
42	```php
43	/**
44	* @dataProvider additionProvider
45	*/
46	public function testAdd(int $a, int $b, int $expected): void
47	{
48	$this->assertEquals($expected, $this->calculator->add($a, $b));
49	}
50
51	public static function additionProvider(): array
52	{
53	return [
54	'positive numbers' => [2, 3, 5],
55	'negative numbers' => [-1, -1, -2],
56	'zeros' => [0, 0, 0],
57	'mixed' => [10, -5, 5],
58	];
59	}
60	```
61
62	### Assertions
63
64	```php
65	$this->assertEquals($expected, $actual);
66	$this->assertSame($expected, $actual); // Strict type
67	$this->assertNotEquals($unexpected, $actual);
68	$this->assertTrue($condition);
69	$this->assertFalse($condition);
70	$this->assertNull($value);
71	$this->assertNotNull($value);
72	$this->assertCount(3, $array);
73	$this->assertContains('item', $array);
74	$this->assertArrayHasKey('key', $array);
75	$this->assertInstanceOf(MyClass::class, $obj);
76	$this->assertStringContainsString('sub', $string);
77	$this->assertMatchesRegularExpression('/\d+/', $string);
78	$this->assertEmpty($collection);
79	$this->assertGreaterThan(5, $value);
80	$this->assertJsonStringEqualsJsonString($expected, $actual);
81	```
82
83	### Mocking
84
85	```php
86	public function testCreateUser(): void
87	{
88	$mockRepo = $this->createMock(UserRepository::class);
89	$mockRepo->expects($this->once())
90	->method('save')
91	->with($this->isInstanceOf(User::class))
92	->willReturn(new User(1, 'Alice'));
93
94	$mockEmail = $this->createMock(EmailService::class);
95	$mockEmail->expects($this->once())
96	->method('sendWelcome')
97	->with('alice@test.com');
98
99	$service = new UserService($mockRepo, $mockEmail);
100	$result = $service->createUser('alice@test.com', 'Alice');
101
102	$this->assertEquals(1, $result->getId());
103	}
104	```
105
106	### Lifecycle
107
108	```php
109	public static function setUpBeforeClass(): void { } // Once before all
110	protected function setUp(): void { } // Before each test
111	protected function tearDown(): void { } // After each test
112	public static function tearDownAfterClass(): void { } // Once after all
113	```
114
115	### Anti-Patterns
116
117	\| Bad \| Good \| Why \|
118	\|-----\|------\|-----\|
119	\| `assertEquals` for strict \| `assertSame` for type+value \| Type coercion \|
120	\| No data providers \| `@dataProvider` \| DRY \|
121	\| Global state \| `setUp()`/`tearDown()` \| Isolation \|
122	\| No groups \| `@group smoke` \| Run subsets \|
123
124	## Setup: `composer require --dev phpunit/phpunit`
125	## Run: `./vendor/bin/phpunit` or `./vendor/bin/phpunit --group smoke`
126	## Config: `phpunit.xml` with testsuites and coverage
127
128	## Deep Patterns
129
130	See `reference/playbook.md` for production-grade patterns:
131
132	\| Section \| What You Get \|
133	\|---------\|-------------\|
134	\| §1 Project Setup \| composer.json, phpunit.xml with suites, coverage config, project structure \|
135	\| §2 Test Patterns \| Assertions, #[DataProvider], Generator yields, strict comparisons \|
136	\| §3 Mocking \| createMock with callbacks, Mockery spies, consecutive returns \|
137	\| §4 Test Doubles \| In-memory fakes, repository pattern, test helpers \|

139	\| §6 Exception Testing \| Detailed exception assertions, warning testing \|
140	\| §7 HTTP & API Testing \| Symfony WebTestCase, auth, validation, pagination \|
141	\| §8 Database Testing \| Transaction rollback, repository integration, Doctrine \|
