README

This extension for phpspec provides a powerful code generator:

  • method generation:
    • it inserts method at the end of the class
    • it typehints arguments (uses interface when possible)
    • it names object arguments after their type (strips Interface suffix from names)
    • it names scalar arguments after a generic name (argument)
    • it adds number on names that could collide (e.g. $argument1, $argument2)
  • constructor generation, same as method except:
    • it inserts constructor at the begining of the class
    • it inserts properties with initialization for each constructor arguments

Note: Currently it is not possible to provide custom templates to SpecGen (it is not compatible with phpspec templates).

Installation

First install it using Composer:

composer require --dev memio/spec-gen:^0.10.1

Then enable it in phpspec.yml:

extensions:
 Memio\SpecGen\MemioSpecGenExtension: ~

Version guide:

  • using phpspec 6? Then use spec-gen v0.10
  • using phpspec 5? Then use spec-gen v0.9
  • using phpspec 4? Then use spec-gen v0.8
  • using phpspec 3 and PHP 7? Then use spec-gen v0.7
  • using phpspec 3 and PHP 5.6? Then use spec-gen v0.6
  • using phpspec 2? Then use spec-gen v0.4

Full example

Let's write the following specification:

<?php

namespace spec\Vendor\Project;

use Vendor\Project\Service\Filesystem;
use Vendor\Project\File;
use PhpSpec\ObjectBehavior;

class TextEditorSpec extends ObjectBehavior
{
 const FILENAME = '/tmp/file.txt';
 const FORCE_FILE_CREATION = true;

 function let(Filesystem $filesystem)
 {
 $this->beConstructedWith($filesystem);
 }

 function it_creates_new_files(File $file, Filesystem $filesystem)
 {
 $filesystem->exists(self::FILENAME)->willReturn(false);
 $filesystem->create(self::FILENAME)->willReturn($file);

 $this->open(self::FILENAME, self::FORCE_FILE_CREATION)->shouldBe($file);
 }
}

Executing the specifications (phpspec run) will generate the following class:

<?php

namespace Vendor\Project;

use Vendor\Project\Service\Filesystem;

class TextEditor
{
 private $filesystem;

 public function __construct(Filesytem $filesystem)
 {
 $this->filesystem = $filesystem;
 }

 public function open(string $argument1, bool $argument2)
 {
 }
}

Now we can start naming those generic arguments and write the code.

Roadmap

  • constructor property promotion
  • return type hints
  • method body (mirror of test method body)
  • better scalar argument naming (based on names used in test)
