PHP PHPUnit assertIsBool()用法及代碼示例

assertIsBool()函數是PHPUnit中的內置函數，用於斷言實際獲得的值是否為Bool。如果實際值為Bool，則此斷言將返回true，否則Bool則返回false。如果為真，則通過斷言的測試用例，否則測試用例失敗。

用法:

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

參數：此函數接受上述和以下描述的兩個參數：

$actualvalue:此參數可以是代表實際數據的任何類型。
$message:此參數采用字符串值。當測試用例失敗時，此字符串消息將顯示為錯誤消息。

以下示例說明了PHPUnit中的assertIsBool()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeForassertIsNotBooltrue() 
    {    $actual = 420; 
        // Assert function to test whether actual  
        // value is (true or false) or not 
        $this->assertIsBool(  
          
            $actual,  
            "actual value is Bool or not"
        ); 
          
    } 
      
    public function testNegativeForassertIsNotBoolFalse() 
    {   
        $actual = 220; 
        // Assert function to test whether actual 
        // value is (true or false) or not 
          
        $this->assertIsBool(  
          
            $actual,  
            "actual value is Bool or not"
        ); 
    }   
 }  
?>
