assertContainsOnly()
assertContainsOnly(string $type, Iterator|array $haystack[, boolean $isNativeType = null, string $message = ''])
Reports an error identified by $message
if $haystack
does not contain only variables of type $type
.
$isNativeType
is a flag used to indicate whether $type
is a native PHP type or not.
assertNotContainsOnly()
is the inverse of this assertion and takes the same arguments.
assertAttributeContainsOnly()
and assertAttributeNotContainsOnly()
are convenience wrappers that use a public
, protected
, or private
attribute of a class or object as the haystack.
