README

Validator is a lightweight PHP library for validating the structure of data retrieved from an external json API.

The library was originally created for use in acceptance api tests, but can be used anywhere else as well.

Specific

The library was made to test json compatible data structures. Array key validation is not supported.

Installation

Use the package manager composer to install.

composer require dentelis/php-json-structure-validator

Usage

You can use library with(or without) any testing framework you want.

See dentelis/phpunit-json-assert for PhpUnit support.

//object example
$user = (new ObjectType())
    ->addProperty('name', (new StringType())->assertNotEmpty())
    ->addProperty('email', (new StringType())->assertEmail());
    
$data = json_decode('{"name":"user", "email":"user@example.com"}');
try {
    $user->validate($data);
} catch (ValidationException $e) {
    //do smth
    
}

//array of objects
$users = (new ArrayType())
    ->assertNotEmpty()
    ->assertType($user);

$data = json_decode('[{"name":"user", "email":"user@example.com"},{"name":"user", "email":"user@example.com"}]');
try {
    $users->validate($data);
} catch (ValidationException $e) {
    //do smth

}

See examples directory for full example.
