PHP: how to assert that an array contains a certain value?

Question

I'm writing some unit tests using phpunit and I now want to assert that an array contains a certain value, but the only function I can find is assertArrayHasKey(). There is no assertArrayHasValue whatsoever.

So to be clear I want something like this:

$a = [5, 8, 16];
assertArrayHasValue(8, $a);

All tips are welcome!

Here is a list of assertion as well, maybe it will help. stackoverflow.com/questions/569369/… — Heath N

You can do it with function assertContains() of PHPUnit:

try this:

$a = [5, 8, 16];
$this->assertContains(8, $a);

ASSERT_CONTAINS

You can use ouzo goodies library.

 $animals = ['cat', 'dog', 'pig'];
 Assert::thatArray($animals)->hasSize(3)->contains('cat');

There are a lot of interesting assertions that can be chained e.g.

Assert::thatArray($users)->onMethod('getAge')->containsOnly(35, 24);

See http://ouzo.readthedocs.org/en/latest/documentation/tests.html#array-assertions
