WebConfigurer implements ServletContextInitializer { @Override public void onStartup(ServletContext servletContext) throws ServletException { if (env.getActiveProfiles().length != 0) { log.info("Web application configuration, using profiles: {}", (Object[]) env.getActiveProfiles()); } log.info("Web application fully configured"); } WebConfigurer(Environment env, JHipsterProperties jHipsterProperties); @Override void onStartup(ServletContext servletContext); @Bean CorsFilter corsFilter();  }### Answer:
@Test public void testStartUpProdServletContext() throws ServletException { env.setActiveProfiles(JHipsterConstants.SPRING_PROFILE_PRODUCTION); webConfigurer.onStartup(servletContext); }
