PHPUnit assertIsNotResource() Function
  • Last Updated : 07 Aug, 2020

The assertIsNotResource() function is a builtin function in PHPUnit and is used to assert whether the given variable is not Resource. This assertion will return true in the case if the given variable is not Resource else returns false. In case of true the asserted test case got passed else test case got failed.

Syntax:

assertIsNotResource($actual[, $message = ''])

Parameters: This function accepts two parameters as mentioned above and described below:

  • $variable: This parameter is of any type of variable which represents the actual data.
  • $message: This parameter takes a string value. When the test case got failed this string message got displayed as error message.

Below examples illustrate the assertIsNotResource() function in PHPUnit:

Example 1:



PHP




<?php 
use PHPUnit\Framework\TestCase; 
    
class GeeksPhpunitTestCase extends TestCase 
    public function testNegativeTestcaseForassertIsNotResource()
    
       $variable fopen('http://www.google.com','r');
        // Assert function to test whether assert
        //  variable is not resource
        $this->assertIsNotResource(
            $variable,
            "assert variable is not resource"
        );
       fclose($variable);
    }
   
 
?>
