assertPartiallySame()

Arguments:

• array|object $expected
• mixed $actual
• string $message = ''
• bool $strict = true
• bool $allowNull = false

Checks if $actual contains values as described in $expected. Unlike assertSame() and assertEquals() $actual can contain other fields which are not important in this test.

$expected = [
    'first_name' => 'John',
    'last_name' => 'Tester',
];

$actual = [
    'first_name' => 'John',
    'last_name' => 'Tester',
    'email' => 'john@example.com',
    'age' => 25,
];

$this->assertPartiallySame($expected, $actual); // we check only important fields for us

• $actual and $expected are compared as arrays. These can be objects but will be cast to arrays.
• If $actual is not array or object it leads to fail.
• If arrays are associative order of keys is not important.
• $strict = false - allows compare int with string and int with bool.
• $allowNumm = true - if a key is missing in $actual it is equivalent to NULL.
