Testing the value of a prop

[Livijn]

First off, I've looked through a couple of PRs that tried to ease the use of testing with Inertia. I'm not sure why you chose the "unorthodox" way that you did. The testing that exists in Laravel doesn't use closures like this, which is why it feels strange.

$response->assertInertia(function (Assert $page) {
    $page->component('Ads');
    $page->hasAll(['foo', 'bar']);
});

// vs

$response->assertInertiaComponent('Ads');
$response->assertInertiaHasProps(['foo', 'bar']);

So, now to my question. How do I test that a prop is equal to a value?

Based of the name I thought $page->has('foo', ['some', 'array']); would work, but it seems the has() method only allows integers.

Also, the demo app uses a macro instead: https://github.com/inertiajs/pingcrm/blob/master/tests/TestCase.php#L18

I think has is only used to check if a property exists, in the same way Arr::has() works. From looking at the code I think you'd need to use where, so you can check if foo has the value bar using this:

$response->assertInertia(function (Assert $page) {
    $page->component('Ads');

    // Check if the 'foo' key exists
    $page->has('foo');

    // Check if 'foo' has the expected value 'bar'
    $page->where('foo', 'bar');
});

[Livijn]

Yes, that works. But what if I'd wanted to $this->assertArrayHasKey() or any other assertion? Since the props are set to private on the Assert class, we can't access them.

[RobertBoes]

I suppose you could do this:

// Assuming your data looks like this:
// [
//   'foo' => ['some' => 'array'],
// ]

$response->assertInertia(function (Assert $page) {
    // $foo will be ['some' => 'array']
    $foo = $page->prop('foo');

    // Use PHPUnit assertions on the prop
    $this->assertArrayHasKey('some', $foo);
});

Hey @Livijn

I assume you are refering to this PR https://github.com/inertiajs/inertia-laravel/pull/220 ?

This comment made me come here to comment:

However this is not true at all as you will find new laravel versions having a very similar JSON assertion built in to laravel: https://github.com/laravel/framework/pull/36454 . On this PR you'll find a very extensive description on how to use it. IMHO: @claudiodekker 's work has been amazing on the tester and if pingcrm is not using it yet it just means, the core team didn't have to time to convert it. PingCRM is not aimed to be feature complete nor to achieve feature parity. It's just a demo project laying out the very fundamentic way inertia is helping you as a developer

That is true. However, that PR was merged merely 1 day before i posted this issue. So this is still a pretty atypical way of testing in Laravel.

After playing around with this new method of testing, I have grown fond of it. I guess the idea had to marinate a bit.

Totally, we're breaking new ground here @Livijn 😎
