PHPUnit assertIsObject() Function

The assertIsObject() function is a builtin function in PHPUnit and is used to assert whether the actual given content is an object or not. This assertion will return true in the case if the actual given content is object else returns false. In case of true the asserted test case got passed, else test case got failed.

Syntax:

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

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

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

Below example illustrate the assertIsObject() function in PHPUnit:

Example 1:

PHP




<?php 
use PHPUnit\Framework\TestCase; 
    
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testNegativeTestcaseForassertIsObject() 
    { 
        $actualcontent =  ('lovely laptop');
    
        // Assert function to test whether given 
        // actual content is object or not
        $this->assertIsObject(
            $actualcontent, 
            "actual content is object or not"
        ); 
    } 
} 
    
?>
