Method Details
-
registerExtension
Instantiate an extension of the given type using its default constructor and register it in the registry.A new
Extension
should not be registered if an extension of the given type already exists in the registry or a parent registry.- Parameters:
extensionType
- the type of extension to register- Since:
- 5.8
-
registerExtension
Register the suppliedExtension
, without checking if an extension of that type has already been registered.Semantics for Source
If an extension is registered declaratively via
@ExtendWith
, thesource
and theextension
should be the same object. However, if an extension is registered programmatically via@RegisterExtension
, thesource
object should be theField
that is annotated with@RegisterExtension
. Similarly, if an extension is registered programmatically as a lambda expression or method reference, thesource
object should be the underlyingMethod
that implements the extension API.- Parameters:
extension
- the extension to register; nevernull
source
- the source of the extension; nevernull
-
registerSyntheticExtension
Register the suppliedExtension
as a synthetic extension, without checking if an extension of that type has already been registered.- Parameters:
extension
- the extension to register; nevernull
source
- the source of the extension; nevernull
