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:
- $key :此参数表示数组要包含的键的名称。
- $array :此参数是要搜索其键的数组。
- $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");
}
}
?>
