PHPUnit: Verifying that array has a key with given value

Question

Given the following class:

<?php class Example {     private $Other;      public function __construct ($Other)     {         $this->Other = $Other;     }      public function query ()     {            $params = array(             'key1' => 'Value 1'             , 'key2' => 'Value 2'         );          $this->Other->post($params);     } } 

And this testcase:

<?php require_once 'Example.php'; require_once 'PHPUnit/Framework.php';  class ExampleTest extends PHPUnit_Framework_TestCase {      public function test_query_key1_value ()     {            $Mock = $this->getMock('Other', array('post'));          $Mock->expects($this->once())               ->method('post')               ->with(YOUR_IDEA_HERE);          $Example = new Example($Mock);         $Example->query();     } 

How do I verify that $params (which is an array) and is passed to $Other->post() contains a key named 'key1' that has a value of 'Value 1'?

I do not want to verify all of the array - this is just a sample code, in actual code the passed array has a lot more values, I want to verify just a single key/value pair in there.

There is $this->arrayHasKey('keyname') that I can use to verify that the key exists.

There is also $this->contains('Value 1'), which can be used to verify that the array has this value.

I could even combine those two with $this->logicalAnd. But this of course does not give the desired result.

So far I have been using returnCallback, capturing the whole $params and then doing asserts on that, but is there perhaps another way to do what I want?

Answer 1

The $this->arrayHasKey('keyname'); method exists but its name is assertArrayHasKey :

// In your PHPUnit test method $hi = array(     'fr' => 'Bonjour',     'en' => 'Hello' );  $this->assertArrayHasKey('en', $hi);    // Succeeds $this->assertArrayHasKey('de', $hi);    // Fails
