如何测试spring配置类? [英] How to test spring configuration classes?

问题描述

我有一个Spring应用程序，其中有配置类，其中包含实例Bean.

I have a spring application whith configuration classes where instance the beans.

应用程序类:

@Configuration
@EnableAspectJAutoProxy
@EnableSpringDataWebSupport
@EnableTransactionManagement
@ComponentScan(basePackageClasses = Application.class)
@PropertySource(value = {"classpath:foo.properties"})
@EnableJpaRepositories(basePackageClasses = Application.class)
@EnableJpaAuditing
public class Application {

    @Inject
    private Environment env;

    @Bean
    JndiTemplate jndiTemplate() {
        return new JndiTemplate();
    }

    @Bean
    public DataSource dataSource() {        
        DataSource dataSource = getDataSource();
        if (dataSource == null) {
            dataSource = new BasicDataSource();
            ((BasicDataSource) dataSource).setUsername(env.getProperty("jdbc.user"));
            ((BasicDataSource) dataSource).setPassword(env.getProperty("jdbc.password""));

            ((BasicDataSource) dataSource).setDriverClassName(env.getProperty("jdbc.driverClassName"));
            ((BasicDataSource) dataSource).setUrl(env.getProperty("jdbc.url"));
        }
        return dataSource;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        EntityManagerFactory factory = entityManagerFactory().getObject();
        return new JpaTransactionManager(factory);
    }

    //....
}

MvcConfiguration类:

MvcConfiguration class:

@Configuration
@ComponentScan(basePackageClasses = Application.class, includeFilters = @Filter({Controller.class, Component.class}), useDefaultFilters = true)
class MvcConfiguration extends WebMvcConfigurationSupport {
    private static final String MESSAGES = "classpath:/i18n";

    private static final String VIEW_PREFIX = "/WEB-INF/views/";

    @Inject
    private Environment env;

    @Override
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        RequestMappingHandlerMapping requestMappingHandlerMapping = super.requestMappingHandlerMapping();
        requestMappingHandlerMapping.setUseSuffixPatternMatch(false);
        requestMappingHandlerMapping.setUseTrailingSlashMatch(true);

        return requestMappingHandlerMapping;
    }

    @Bean(name = "messageSource")
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename(MESSAGES);
        messageSource.setCacheSeconds(5);

        return messageSource;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/").addResourceLocations("/static/**");
    }

    @Bean
    public MultipartResolver filterMultipartResolver(){
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        resolver.setMaxUploadSize(Long.parseLong(env.getProperty("multipart.max.size")));
        return resolver;
    }

    //....

}

和SecurityConfiguration类:

And SecurityConfiguration class:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }


    //....

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //Logout por POST con el valor de token csrf
        http.authorizeRequests()
                .antMatchers("/static/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .failureUrl("/login?error=1")
                .loginProcessingUrl("/authenticate")
                .and()
            .logout()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/signin")
                .permitAll();
    }

}

如何使用JUnit测试它们?如何测试在春季上下文中创建的bean?

How I can test them with JUnit? How to test the beans are created in the spring context?

推荐答案

我相信只有通过集成测试才能实现.

I believe this is will only be achieved with an Integration Test.

单元测试的目的不是检查整个Spring Context是否成功创建.

The purpose of Unit Tests are not to check if the whole Spring Context is being created with success.

您可以使用模拟等检查单元配置中的每种配置方法是否正常，但是整个Spring Context都是集成测试.

You can test each configuration method with a Unit Test by using mocks and etc to check if they are ok, but the whole Spring Context thing is an Integration test.

我以前通过做Spring Docs所说的"Spring Unit Test"来进行配置测试(对我来说，它更像是对Controllers + Views的集成测试)

I use to do this Configuration Test by doing what Spring Docs call "Spring Unit Test" (that for me is more like a Integration Test of the Controllers + Views)

这个想法是，如果您可以运行用于控制器集成测试的Spring Context，那么您的Configurations就可以了.

The idea is that, if you can get a Spring Context running for a Controller integration Test, than your Configurations are OK.

关于如何进行这种测试的春季文档，整整有一章. http://docs.spring.io/spring /docs/current/spring-framework-reference/html/testing.html

There is a whole chapter on spring docs on how to do that kind of test. http://docs.spring.io/spring/docs/current/spring-framework-reference/html/testing.html
