Time Zone for Spring Mock MVC tests

Question

How can the time zone for SpringMock MVC tests be set? Our Spring Boot applications are all running with

TimeZone.setDefault(TimeZone.getTimeZone("UTC"));

set at Application startup. But I found no way to set this for the MockMvcRequestBuilders. Setting it manually (in test or BeforeClass) didn't change anything = still machine time-zone is used...

You can do it using a @Configuration class. If you annotate your tests with @SpringBootTest, as Spring loads the context before execute testes, you'll have your default timezone configurated correctly.

I'd just inserted this class below in one of my projects and all my @SpringBootTest annotated tests started to respect UTC timezone. You can replace to use the timezone you want to.

@Configuration
public class TimeZoneConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(TimeZoneConfig.class);

    @Bean
    public TimeZone timeZone(){
        TimeZone defaultTimeZone = TimeZone.getTimeZone("UTC");
        TimeZone.setDefault(defaultTimeZone);
        LOGGER.info("Spring boot application running in UTC timezone :"+new Date());
        return defaultTimeZone;
    }

}
