Test an array and random value PHPunit-CodePudding

I have a little problem with my unit test and an array generated "randomly",

I have something looking like this :

return [
 'foo' => $this->faker->sentence(),
 'bar' => [
    'baz' => $this->faker->realText(),
    'booz' => [
       'baaz' => $this->faker->title()
    ]
 ]
];

$this->faker->xxx generate random strings or whatever, but I want to test the "shape" of the array, I want to ensure I have :

foo in first children array, bar too Bar have baz and booz at the same level and booz have a baaz in children.

But I could not find how to do that, I have tried something like this but it is not working :/

$this->assertEquals([
  'foo' => \Mockery::any(),
  'bar' => [
    'baz' => \Mockery::any(),
  ],
], $class->method());

Maybe this is not possible and I should find a way to simply test the keys in the array?

Maybe array_diff_key can help me here?

Use multiple assertions:

$data = $class->method();
$this->assertTrue(isset($data[‘foo’]);
$this->assertTrue(isset($data[‘bar’]);
$this->assertTrue(is_array($data[‘bar’]);
$this->assertTrue(isset($data[‘bar’][‘baz’]);
$this->assertTrue(isset($data[‘bar’][‘booz’]);
$this->assertTrue(is_array($data[‘bar’][‘booz’]);
$this->assertTrue(isset($data[‘bar’][‘booz’][‘baaz’]);

CodePudding user response：

You should always try to use the most expressive assertion. assertEquals is for equality, assertTrue for booleans. But you only want to check the structure, so assertArrayHasKey', assertIsStringandassertIsArray` are your friends.

$this->assertArrayHasKey($data['foo']);
$this->assertIsString($data['foo']);

$this->assertIsArray($data['bar']);
$this->assertArrayHasKey($data['bar']['baz']);
$this->assertIsString($data['bar']['baz']);
