Golden Testing for Pest

Provides a toEqualGolden assertion, same as toEqual, but when null is given as argument, the test file is automatically edited and null is substituted with the actual value.

So, if you add:

expect(['color' => 'golden'])
    ->toEqualGolden(null);

...to your test and execute it. The null expression is replaced by the actual value:

expect(['color' => 'golden'])
    ->toEqualGolden(['color' => 'golden']);

In principle, it's about saving oneself the recurring work of writing, updating and copying an expectation.

Installation

You can install the package via composer:

composer require holgerk/pest-plugin-equal-golden --dev

Usage

Just pass null to the toEqualGolden expectation and null will be automatically replaced during the first test run.

expect($actual)->toEqualGolden(null);

Later you can edit the expectation by hand or insert null again to have it automatically replaced.
If you want to regenerate all expectations at once you can add the argument: --update-golden to your pest invocation.

# regenerate all expectations at once from their actual values
./vendor/bin/pest --update-golden

  This plugin also facilitates the automatic generation of expectations from the actual value, but it will store the generated expectation in separate files.
