* This set of tests refutes the claims made in
* <a href="https://jira.spring.io/browse/SPR-9051" target="_blank">SPR-9051</a>.
*
* <p><b>The Claims</b>:
*
* <blockquote>
* When a {@code @ContextConfiguration} test class references a config class
* missing an {@code @Configuration} annotation, {@code @Bean} dependencies are
* wired successfully but the bean lifecycle is not applied (no init methods are
* invoked, for example). Adding the missing {@code @Configuration} annotation
* solves the problem, however the problem and solution isn't obvious since
* wiring/injection appeared to work.
