Example 1 with IInjectorProvider

the class InjectionExtension method getOrCreateInjectorProvider.

 * annotation on the required test classes along the {@link ExtensionContext#getParent() hierarchy} of contexts.
 *
 * If the injector provider can be found, it will be reflectively instantiated and cached. Only one instance of any
 * given injector provider will be created.
