PHP VCR

Record your test suite's HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests.

Description

This is a port of VCR for ruby.

Record your test suite's HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests. A bit of documentation can be found on the php-vcr website.

Disclaimer: Doing this in PHP is not as easy as in programming languages which support monkey patching (I'm looking at you, Ruby) – this project is not yet fully tested, so please use at your own risk!

Features

• Automatically records and replays your HTTP(s) interactions with minimal setup/configuration code.
• Supports common http functions and extensions
  • everything using streamWrapper: fopen(), fread(), file_get_contents(), ... without any modification (except $http_response_header see #96)
  • SoapClient by adding \VCR\VCR::turnOn(); in your tests/bootstrap.php
  • curl(), by adding \VCR\VCR::turnOn(); in your tests/bootstrap.php
• The same request can receive different responses in different tests -- just use different cassettes.
• Disables all HTTP requests that you don't explicitly allow by setting the record mode
• Request matching is configurable based on HTTP method, URI, host, path, body and headers, or you can easily implement a custom request matcher to handle any need.
• The recorded requests and responses are stored on disk in a serialization format of your choice (currently YAML and JSON are built in, and you can easily implement your own custom serializer)
• Supports PHPUnit annotations.

Usage example

Using static method calls:

class VCRTest extends TestCase
{
    public function testShouldInterceptStreamWrapper()
    {
        // After turning on the VCR will intercept all requests
        \VCR\VCR::turnOn();

        // Record requests and responses in cassette file 'example'
        \VCR\VCR::insertCassette('example');

        // Following request will be recorded once and replayed in future test runs
        $result = file_get_contents('http://example.com');
        $this->assertNotEmpty($result);

        // To stop recording requests, eject the cassette
        \VCR\VCR::eject();

        // Turn off VCR to stop intercepting requests
        \VCR\VCR::turnOff();
    }

    public function testShouldThrowExceptionIfNoCasettePresent()
    {
        $this->setExpectedException(
            'BadMethodCallException',
            "Invalid http request. No cassette inserted. Please make sure to insert "
            . "a cassette in your unit test using VCR::insertCassette('name');"
        );
        \VCR\VCR::turnOn();
        // If there is no cassette inserted, a request throws an exception
        file_get_contents('http://example.com');
    }
}

You can use annotations in PHPUnit by using phpunit-testlistener-vcr:

class VCRTest extends TestCase
{
    /**
     * @vcr unittest_annotation_test
     */
    public function testInterceptsWithAnnotations()
    {
        // Requests are intercepted and stored into  tests/fixtures/unittest_annotation_test.
        $result = file_get_contents('http://google.com');

        $this->assertEquals('This is a annotation test dummy.', $result, 'Call was not intercepted (using annotations).');

        // VCR is automatically turned on and off.
    }
}

Installation

Simply run the following command:

$ composer require --dev php-vcr/php-vcr
