Installation
You can install the package via composer:
composer require ghostwriter/psalm-sandbox --dev
Usage
You can create a test for your plugin by extending the AbstractPsalmSandboxTestCase class.
eg. tests/Unit/ExamplePluginTest.php
<?php declare(strict_types=1); namespace Vendor\PackageTests\Unit; use Ghostwriter\PsalmSandbox\AbstractPsalmSandboxTestCase; use Psalm\Issue\CodeIssue; use Psalm\Issue\MissingReturnType; use Psalm\Plugin\PluginEntryPointInterface; use Vendor\Package\ExamplePlugin; final class ExamplePluginTest extends AbstractPsalmSandboxTestCase { /** * @var class-string<PluginEntryPointInterface> */ public const PLUGINS = [ExamplePlugin::class]; /** * @var array<class-string<CodeIssue>> */ public const ISSUES = [MissingReturnType::class]; }
You can then run your tests using PHPUnit.
vendor/bin/phpunit
Plugin Development
Example Directory Structure
Your plugin should have the following directory structure:
composer.json
ExamplePlugin.php
src/
│ {PsalmIssueType}/
│ │ {FixIssue}.php
│ │ {ReportIssue}.php
│ │ {SuppressIssue}.php
│ MissingReturnType/
│ │ FixMissingReturnType.php
│ │ ReportMissingReturnType.php
│ │ SuppressMissingReturnType.php
tests/
│ Fixture/
│ │ {PsalmIssueType}/
│ │ │ fix-{PsalmIssueType}.php.inc
│ │ │ report-{PsalmIssueType}.php.inc
│ │ │ suppress-{PsalmIssueType}.php.inc
│ │ MissingReturnType/
│ │ │ fix-0001.php.inc
│ │ │ fix-missing-returntype.php.inc
│ │ │ report-0001.php.inc
│ │ │ report-missing-returntype.php.inc
│ │ │ suppress-0001.php.inc
│ │ │ suppress-missing-returntype.php.inc
│ Unit/
│ │ ExamplePluginTest.php
Example Fix Test
When you run vendor/bin/psalm --alter, it will automatically fix the code for you.
To create a Fix test, you need to create a file in the tests/Fixture/{PsalmIssueType} directory.
The file name should be prefixed with fix- and any unique identifier, e.g. fix-0001.php.inc.
The file MUST use --FIX-- to separate the before and after code.
The file should be structured as follows:
<?php declare(strict_types=1); namespace Vendor\PackageTests\Fixture\MissingReturnType; final class FixMissingReturnType { public function fixMissingReturnType() { } } ?> --FIX-- <?php declare(strict_types=1); namespace Vendor\PackageTests\Fixture\MissingReturnType; final class FixMissingReturnType { public function fixMissingReturnType(): void { } } ?>
Example Report Test
When you run vendor/bin/psalm, it will report the issue in your code.
To create a Report test, you need to create a file in the tests/Fixture/{PsalmIssueType} directory.
The file name should be prefixed with report- and any unique identifier, e.g. report-0001.php.inc.
The file should be structured as follows:
<?php declare(strict_types=1); namespace Vendor\PackageTests\Fixture\MissingReturnType; final class ReportMissingReturnType { public function reportMissingReturnType() { } }
Example Suppress Test
You can suppress the issue in your code by adding the @psalm-suppress annotation, adding suppressions to your psalm.xml file, or using a plugin.
To create a Suppress test, you need to create a file in the tests/Fixture/{PsalmIssueType} directory.
The file name should be prefixed with suppress- and any unique identifier, e.g. suppress-0001.php.inc.
The file should be structured as follows:
<?php declare(strict_types=1); namespace Vendor\PackageTests\Fixture\MissingReturnType; final class SuppressMissingReturnType { /** * @psalm-suppress MissingReturnType */ public function suppressMissingReturnType() { } }
