Laravel - Assert json array ids using wildcard - laravel

Question

In my application I have a response like this:
{
"items": [
{
"id": 10,
"field": "foo"
},
{
"id": 20,
"field": "bar"
}
]
}
I need to test the content of items and validate each id.
I've tried many solutions but no one works, for example (this is just a kind of pseudo-code):
assertJson(fn (AssertableJson $json) =>
$json->where('items.*.id', [10, 20])
)
Is there a way to use a wildcard to pick every ID and validate using an array?

Answer 1

You can use array_filter:
$idArray = [10, 20];
$myObj = json_decode($json); // Turn JSON to obj
$items = $myObj["items"]; // Get items from object
// Filter the items for items that aren't in the ID list
$invalidItems = array_filter($items, function ($el) {
// If the item has an id which isn't in the array, return true
return !in_array($el["id"], $idArray);
});
// This returns true if we found 0 items with IDs not in the ID list
return $invalidItems == [];
You can similarly use array_map to simplify your array, then compare it to your ID array:
$myObj = json_decode($json); // Turn JSON to obj
$items = $myObj["items"]; // Get items from object
$outIdArray = array_map(function($el) {
return $el["id"];
}, $items);
// Compare $outIdArray to [10, 20]

Not tested yet but below should work.
We attach an each on each child element under items and add a callback to where on that id key of each child.
<?php
assertJson(fn (AssertableJson $json) =>
$json->each('items', fn (AssertableJson $childJson) =>
$childJson->where('id', fn($idVal) =>
in_array($idVal, [10,20])
)
)
)
