+# eventjet/test-double
+
+Reusable PSR-compliant test doubles for PHP — drop-in fakes for HTTP clients, loggers, and SOAP clients with a fluent matcher API and descriptive failure messages.
+
+## Requirements
+
+- PHP 8.3+
+- `ext-soap` (only required when using `TestSoapClient`)
+
+## Installation
+
+```bash
+composer require --dev eventjet/test-double
+```
+
+## Test Doubles
+
+| Class | Implements | Documentation |
+|---|---|---|
+| `TestLogger` | PSR-3 `LoggerInterface` | [doc/TestLogger.md](doc/TestLogger.md) |
+| `TestHttpClient` | PSR-18 `ClientInterface` | [doc/TestHttpClient.md](doc/TestHttpClient.md) |
+| `TestSoapClient` | Custom SOAP client | [doc/TestSoapClient.md](doc/TestSoapClient.md) |
+
+Reusable matchers (`Str::regex()`, `Val::eq()`) are documented in [doc/Matchers.md](doc/Matchers.md).
+
+## Quick Start
+
+### TestLogger
+
+```php
+use Eventjet\TestDouble\TestLogger;
+use PHPUnit\Framework\TestCase;
+use Psr\Log\LogLevel;
+
+final class MyServiceTest extends TestCase
+{
+    public function testLogsWarningOnFailure(): void
+    {
+        $logger = new TestLogger();
+        $service = new MyService($logger);
+
+        $service->doSomething();
+
+        $result = $logger->once(
+            TestLogger::and(
+                TestLogger::level(LogLevel::WARNING),
+                TestLogger::message('Operation failed')
+            )
+        );
+        self::assertTrue($result);
+    }
+}
+```
+
+### TestHttpClient
+
+```php
+use Eventjet\TestDouble\TestHttpClient;
+use GuzzleHttp\Psr7\HttpFactory;
+use PHPUnit\Framework\TestCase;
+
+final class MyApiClientTest extends TestCase
+{
+    public function testFetchesUser(): void
+    {
+        $factory = new HttpFactory();
+        $httpClient = new TestHttpClient();
+        $httpClient->map(
+            TestHttpClient::path('/api/users/1'),
+            $factory->createResponse(200)->withBody(
+                $factory->createStream('{"id":1,"name":"John"}')
+            )
+        );
+
+        $apiClient = new MyApiClient($httpClient);
+        $user = $apiClient->getUser(1);
+
+        self::assertSame('John', $user->name);
+    }
+}
+```
