README

Makes Psalm understand Pest tests.

composer require --dev alies-dev/psalm-plugin-pest
vendor/bin/psalm-plugin enable alies-dev/psalm-plugin-pest

Requires PHP 8.3+, Psalm 6.19+ or 7 (including dev-master) and Pest 4 or 5. Your tests/ directory must be in <projectFiles>.

What it does

• Types $this in test, hook and dataset closures as the TestCase from uses() / pest()->extend(), including traits from uses() / ->use().
• Declares $this->x assigned in beforeEach() (in the file or in tests/Pest.php hooks) for the tests it applies to.
• Types test() with no arguments as the bound TestCase, and resolves higher-order tests like it('x')->actingAsAdmin().
• Types expectation chains: ->not, ->each, higher-order members (expect($user)->name->toBe('Ada')), and expect($v) as Expectation<T>.
• Narrows variables after type assertions: expect($user)->not->toBeNull() makes $user non-null.
• Stops reporting InternalMethod on Pest's public API.

Known limitations

• tests/Pest.php is looked up next to your Psalm config, and a test file outside tests/ keeps Pest's own types.
• Files are parsed, never executed: a boot file with dynamic uses() calls disables TestCase resolution for the suite.
• Custom expectations from expect()->extend() are still reported.
• Narrowing works on plain variables only, not $this->prop.
