PHPUnit | AssertArrayHasKey () function

Syntax :
assertArrayHasKey (mixed $key, array $array [, string $message = ’’]) 
Parameters : This function takes three parameters as shown in the above syntax. The parameters are described below:
  • $key : This parameter represents the name of the key that will be contained in the array.
  • $array : This parameter is the array to search for the key for.
  • $message : This parameter accepts a string value. When the test case failed, this string message was displayed as an error message.
  • The following programs illustrate the assertArrayHasKey() function: Program 1 : use PHPUnitFrameworkTestCase; class GeeksPhpunitTestCase extends TestCase { public function testNegativeTestcaseForArrayHasKey() { // array for testing $array  = array ( ’ geek’ = > ’engineerForengineer’ ,); // assert function to check if geek is an array key $this -> assertArrayHasKey ( ’engineer’ , $array , "Array doesn’t contains’ engineer’ as key " ); } }  
    ?>
