@Deprecated
/**
 * Use the Spring test annotations in Thucydides tests.
 *
 * @author johnsmart
 * @deprecated Replaced by {@see net.serenitybdd.junit.spring.integration.SpringIntegrationMethodRule},
 * which doesn't use the deprecated {@see org.junit.rules.TestWatchman}, and also works together with
 * {@see net.serenitybdd.junit.spring.integration.SpringIntegrationClassRule}.
 * However, the suggested replacements do not support Spring Framework 2.5,
 * while this class retains support for Spring Framework 2.5.
