TestInstancePreConstructCallbackdefines the API for
Extensionsthat wish to be invoked prior to creation of test instances.
This extension is a symmetric counterpart to
The use cases for this extension may include preparing context-sensitive arguments
that are injected into the instance's constructor.
Extensions that implement
TestInstancePreConstructCallback must be
registered at the class level if the test class is configured with
@TestInstance(Lifecycle.PER_CLASS) semantics. If the test
class is configured with
TestInstancePreConstructCallback extensions may be registered at the
class level or at the method level. In the latter case, the extension will
only be applied to the test method for which it is registered.
