PHP PHPUnit assertNotFalse()用法及代碼示例

assertNotFalse()函數是PHPUnit中的內置函數,用於斷言條件值是否為true。如果條件值為true,則此斷言將返回true,否則返回false。如果為true,則聲明的測試用例通過,否則測試用例失敗。

用法:

assertNotFalse(bool $condition[, string $message = ''])

參數:此函數接受上述和以下所述的三個參數:

  • $condition:此參數是代表true或false的任何類型的值。
  • $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assertNotfalse()函數:

範例1:



PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertNotFalse() 
    {  
        $condition = false; 
          
    
        // Assert function to test whether 
        // condition value is true or not  
        $this->assertNotFalse( 
          
            $condition,  
            "condition is true or false"
        );  
    }  
}  
    
?>

輸出:

        // Assert function to test whether 
        // condition value is true or not  
        $this->assertNotFalse( 
          
            $condition,  
            "condition is true or false"
        );  
    }
