/**
 * If applied, this mock-up will take over calls to {@link AbstractBeanFactory#getBean(String)} in any implementation
 * class, returning instead a {@link Tested @Tested} or {@link Injectable @Injectable} object with the given field name,
 * or a dependency object injected at any level into a {@code @Tested} object.
 * <p/>
 * In case said calls come (indirectly) from a test class having no {@code @Tested} fields, bean lookup will proceed
 * into the actual {@code getBean(String)} implementation method.
 * <p/>
 * Note this mock-up is only useful if the code under test makes direct calls to Spring's {@code getBean(name)} method.
