The assertIsNotBool() function is a builtin function in PHPUnit and is used to assert whether the actually obtained value is Not a Bool. This assertion will return true in the case if the actual value is the Not a Bool else returns false. In case of true the asserted test case got passed else test case got failed.

Syntax:

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

Parameters: This function accepts two parameters as shown in the above syntax. The parameters are described below:

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

Below examples illustrate the assertIsNotBool() function in PHPUnit:

Example 1:

PHP




<?php 
use PHPUnit\Framework\TestCase; 
    
class GeeksPhpunitTestCase extends TestCase 
    public function testNegativeForassertIsNotBooltrue()
    {    $actual = true;
        // Assert function to test whether actual 
        // value is (true or false) or not
        $this->assertIsNotBool( 
          
            $actual
            "actual value is bool or not"
        );
          
    }
   
  
      
    public function testNegativeForassertIsNotBoolFalse()
    {  
        $actual = False;
        // Assert function to test whether actual
        // value is (true or false) or not
          
        $this->assertIsNotBool( 
          
            $actual
            "actual value is bool or not"
        );
    }  
 
?> 


Output:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

        // value is (true or false) or not
        $this->assertIsNotBool(

            "actual value is Bool or not"
        );
          
    }
   
  
      
    public function testNegativeForassertIsNotBoolFalse()
    {  
        $actual = "False";

        );
    }  
 
?>
