Provides a phpspec/prophecy extension for phpstan/phpstan.

Installation

Run

composer require --dev jangregor/phpstan-prophecy

Configuration

Automatic

When using phpstan/extension-installer, no further setup is required.

Manual

When not using phpstan/extension-installer, extension.neon needs to be included in phpstan.neon:

 includes:
+	- vendor/jangregor/phpstan-prophecy/extension.neon

Usage

prophesize() and reveal()

<?php

use PHPUnit\Framework;

final class ExampleTest extends Framework\TestCase
{
 public function testSomething(): void
 {
 $prophecy = $this->prophesize(SomeModel::class);

 $testDouble = $prophecy->reveal();

 // ...
 }
}

💡 With this extension enabled, phpstan/phpstan will understand that $testDouble is an instance of SomeModel.

prophesize(), willExtend(), and reveal()

<?php

use PHPUnit\Framework;

final class ExampleTest extends Framework\TestCase
{
 public function testSomething(): void
 {
 $prophecy = $this->prophesize()->willExtend(SomeModel::class);

 $testDouble = $prophecy->reveal();

 // ...
 }
}

💡 With this extension enabled, phpstan/phpstan will understand that $testDouble is an instance of SomeModel.

prophesize(), willImplement(), and reveal()

<?php

use PHPUnit\Framework;

final class ExampleTest extends Framework\TestCase
{
 public function testSomething(): void
 {
 $prophecy = $this->prophesize(SomeModel::class)->willImplement(SomeInterface::class);

 $testDouble = $prophecy->reveal();

 // ...
 }
}

💡 With this extension enabled, phpstan/phpstan will understand that $testDouble is an instance of SomeModel that also implements SomeInterface.

Method Predictions

<?php

use PHPUnit\Framework;

final class ExampleTest extends Framework\TestCase
{
 public function testSomething(): void
 {
 $prophecy = $this->prophesize(SomeModel::class);

 $prophecy
 ->doubleTheNumber(Argument::is(2))
 ->willReturn(4);

 $testDouble = $prophecy->reveal();

 // ...
 }
}

💡 With this extension enabled, phpstan/phpstan will understand that $prophecy accepts method calls to all methods that are implemented by its prophesized class (or additionally implemented interfaces, when using willImplement()).

Method Arguments

❗ Currently here are no checks in place to validate the arguments of methods that are invoked on prophecies.
