PHP PHPUnit assertIsObject()用法及代码示例


assertIsObject()函数是PHPUnit中的内置函数,用于断言实际给定的内容是否是对象。如果实际给定的内容是object,则此断言将返回true,否则返回false。如果为真,则通过断言的测试用例,否则测试用例失败。

用法:

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

参数:该函数接受两个参数,如下所述:

  • $actual:此参数可以是代表实际内容的任何类型。
  • $message:此参数采用字符串值。当测试用例失败时,此字符串消息将显示为错误消息。

下面的示例说明了PHPUnit中的assertIsObject()函数:

范例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"
        );  
    }  
}  
    
?>

输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

F                                                 1 / 1 (100%)

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