PHPUnit | assertArrayHasKey()函数

assertArrayHasKey ()函数是 PHPUnit 中的内置函数,用于断言数组是否具有特定键。如果数组具有提供的键,则此断言将返回 true,否则返回 false,如果为 true,则断言断言测试用例通过,否则测试用例失败。

语法

assertArrayHasKey(mixed $key, array $array[, string $message = ''])

参数:此函数接受三个参数,如上述语法所示。参数说明如下:

  1. $key :此参数表示数组要包含的键的名称。
  2. $array :此参数是要搜索其键的数组。
  3. $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。

下面的程序说明了 assertArrayHasKey()函数:

程序一



 'geeksForgeeks', );
        // assert function to test whether 'geek' is a key of array
        $this->assertArrayHasKey('geeks', $array, "Array doesn't contains 'geeks' as key");
    }
}
  
?>

输出:

方案二

 'geeksForgeeks', );

        $this->assertArrayHasKey('geeks', $array, "Array doesn't contains 'geeks' as key");
    }
}
  
?>
