MockServer PHP Client

PHP client for MockServer - enables easy mocking of any system you integrate with via HTTP or HTTPS.

Requirements

• PHP 8.1+
• Composer

Installation

composer require mock-server/mockserver-client

Quick Start

<?php

use MockServer\MockServerClient;
use MockServer\HttpRequest;
use MockServer\HttpResponse;
use MockServer\VerificationTimes;

// Connect to MockServer
$client = new MockServerClient('localhost', 1080);

// Create an expectation
$client->when(
    HttpRequest::request()->method('GET')->path('/hello')
)->respond(
    HttpResponse::response()
        ->statusCode(200)
        ->header('Content-Type', 'application/json')
        ->body('{"message":"world"}')
);

// Verify the request was received
$client->verify(
    HttpRequest::request()->path('/hello'),
    VerificationTimes::atLeast(1)
);

// Reset all expectations
$client->reset();

API

Creating Expectations

use MockServer\Times;
use MockServer\TimeToLive;
use MockServer\Delay;
use MockServer\HttpForward;

// Respond with a delay
$client->when(
    HttpRequest::request()->method('POST')->path('/api/data')
        ->header('Content-Type', 'application/json')
        ->jsonBody(['key' => 'value'])
)->respond(
    HttpResponse::response()
        ->statusCode(201)
        ->body('{"id": 1}')
        ->delay(Delay::milliseconds(500))
);

// Match only 3 times, with priority
$client->when(
    HttpRequest::request()->path('/limited'),
    Times::exactly(3),
    TimeToLive::exactly('SECONDS', 60),
    priority: 10
)->respond(
    HttpResponse::response()->statusCode(200)
);

// Forward to another server
$client->when(
    HttpRequest::request()->path('/proxy')
)->forward(
    HttpForward::forward()->host('backend.local')->port(8080)->scheme('HTTP')
);

Verification

use MockServer\VerificationTimes;

// Verify at least once
$client->verify(
    HttpRequest::request()->path('/hello'),
    VerificationTimes::atLeast(1)
);

// Verify exactly 3 times
$client->verify(
    HttpRequest::request()->method('POST')->path('/api'),
    VerificationTimes::exactly(3)
);

// Verify sequence
$client->verifySequence(
    HttpRequest::request()->path('/first'),
    HttpRequest::request()->path('/second')
);

Retrieving Recorded Data

// Retrieve recorded requests
$requests = $client->retrieveRecordedRequests(
    HttpRequest::request()->path('/api')
);

// Retrieve active expectations
$expectations = $client->retrieveActiveExpectations();

// Retrieve log messages
$logs = $client->retrieveLogMessages();

Control Operations

// Clear specific expectations/logs
$client->clear(HttpRequest::request()->path('/old'));
$client->clear(null, 'EXPECTATIONS');  // type: EXPECTATIONS, LOG, or ALL
$client->clearById('my-expectation-id');

// Reset everything
$client->reset();

// Check server status
$status = $client->status();  // ['ports' => [1080]]

// Bind additional ports
$client->bind(1081, 1082);

// Check if server is running
if ($client->hasStarted()) {
    echo "MockServer is ready";
}

Start / Launch MockServer

The PHP client does not include a binary launcher (PHP lacks the native WebSocket and subprocess management required for embedded launch). To start MockServer, use one of the following approaches:

• Docker: docker run -d -p 1080:1080 mockserver/mockserver
• Executable JAR: java -jar mockserver-netty-no-dependencies-<version>.jar -serverPort 1080
• Homebrew: brew install mockserver && mockserver -serverPort 1080
• Another client's launcher: The Node, Python, Ruby, Go, .NET, and Rust clients can each download and launch MockServer automatically without Java or Docker.

See the Running MockServer documentation for all available options.

Building

composer install

Running Tests

Unit tests (no server required):

vendor/bin/phpunit --testsuite Unit

Integration tests (requires a running MockServer):
