PHPUnit assertFalse()函数

assertFalse()函数是 PHPUnit 中的内置函数,用于断言条件值是真还是假。如果条件值为真,则此断言将返回真,否则返回假。如果为真,则断言的测试用例通过,否则测试用例失败。

句法 :

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

参数:该函数接受上面提到的两个参数,如下所述:

  • $condition:这个参数是代表真假的任何类型的值。
  • $message:此参数采用字符串值。当测试用例失败时,此字符串消息显示为错误消息。

下面的例子说明了 PHPUnit:Parameters 中的 assertfalse()函数:

示例 1:

PHP
assertFalse(
         
            $condition,
            "condition is true or false"
        );
    }
}
   
?>


PHP
assertFalse(
         
            $condition,
            "condition is true or false"
        );
    }
}
   
?>
