PHPyh Psalm Tester

Test Psalm via phpt files!

Installation

composer require --dev phpyh/psalm-tester

Basic usage

1. Write a test in phpt format

tests/array_values.phpt

--FILE--
<?php

/** @psalm-trace $_list */
$_list = array_values(['a' => 1, 'b' => 2]);

--EXPECT--
Trace on line 9: $_list: non-empty-list<1|2>

To avoid hardcoding error details, you can use EXPECTF:

--EXPECTF--
Trace on line %d: $_list: non-empty-list<%s>

2. Add a test suite

tests/PsalmTest.php

<?php

use PHPUnit\Framework\Attributes\TestWith;
use PHPUnit\Framework\TestCase;
use PHPyh\PsalmTester\PsalmTester;
use PHPyh\PsalmTester\StaticAnalysisTest;

final class PsalmTest extends TestCase
{
    private ?PsalmTester $psalmTester = null;

    #[TestWith([__DIR__ . '/array_values.phpt'])]
    public function testPhptFiles(string $phptFile): void
    {
        $this->psalmTester ??= PsalmTester::create();
        $this->psalmTester->test(StaticAnalysisTest::fromPhptFile($phptFile));
    }
}

Passing different arguments to Psalm

By default PsalmTester runs Psalm with --no-progress --no-diff --config=psalm.xml.

You can change this at the PsalmTester level:

use PHPyh\PsalmTester\PsalmTester;

PsalmTester::create(
    defaultArguments: '--no-progress --no-cache --config=my_default_config.xml',
);

or for each test individually using --ARGS-- section:

--ARGS--
--no-progress --config=my_special_config.xml
--FILE--
...
--EXPECT--
...
