assertContainsOnly()
assertContainsOnly(string $type, Iterator|array $haystack[, boolean $isNativeType = NULL, string $message = ''])
当 $haystack
并非仅包含类型为 $type
的变量时报告错误,错误讯息由 $message
指定。
$isNativeType
是一个标志,用来表明 $type
是否是原生 PHP 类型。
assertNotContainsOnly()
是与之相反的断言,并接受相同的参数。
assertAttributeContainsOnly()
和 assertAttributeNotContainsOnly()
是便捷包装(convenience wrapper),以某个类或对象的 public
、protected
或 private
属性为搜索范围。
