PEST PHP now includes higher-order expectations, Ray debugging integration, and more!

The community around the Pest PHP testing framework has added some new excellent features, including higher-order expectations, ray() debugging integration, and a VS Code snippets extension for Pest PHP.

Higher Order Expectations

Luke Downing and Sam Rowden contributed higher order expectations API, which allows you to create expectations on methods and properties.

Here’s that before and after code based on the screenshot above:

1// Before
4expect($user->withTitle('Mr'))->toEqual('Mr Nuno Maduro');
6// After
8 ->first_name->toEqual('Nuno')
9 ->last_name->toEqual('Maduro')
10 ->withTitle('Mr')->toEqual('Mr Nuno Maduro');

This feature also works with array data as well:

1expect(['name' => 'Nuno', 'companies' => ['Pest', 'Laravel']])
2 ->name->toEqual('Nuno')
3 ->companies->toHaveCount(2)->each->toBeString

Check out the Expectations documentation for complete examples and information around expectations in PEST.

Use Ray App On Any Expectation

Freek Van der Herten contributed a ray() function to PEST PHP expectations, which can help you easily debug expectations via the Ray app (paid) by changing calls to ray():

Here’s a snippet of what using the ray() function looks like:
