@SpringBootTest tries to connect to actual Ehcache instance

Our Spring Boot application shall be able to fetch data from a remote Ehcache instance. For this, the following configuration has been added.

@Configuration
@EnableCaching
public class EhcacheManager {

    private static final String TERRACOTTA_LINK = "terracotta://";

    private final EhcacheConfiguration ehcacheConfiguration;

    public EhcacheManager(EhcacheConfiguration ehcacheConfiguration) {
        this.ehcacheConfiguration = ehcacheConfiguration;
    }

    @Bean
    PersistentCacheManager persistentCacheManager() {
        return ehCacheManager();
    }

    private PersistentCacheManager ehCacheManager() {
        final String ehcacheURI = TERRACOTTA_LINK + ehcacheConfiguration.getHost() + ":" + ehcacheConfiguration.getPort() + "/" + ehcacheConfiguration.getResource();

        PersistentCacheManager cacheManager = newCacheManagerBuilder()
                .with(cluster(create(ehcacheURI)).autoCreate())
                .build(true);

        CacheConfiguration<String, String> myCache = newCacheConfigurationBuilder(String.class, String.class,
                newResourcePoolsBuilder().with(clusteredDedicated("offheap-1", 50, MB)))
                .withService(withConsistency(EVENTUAL))
                .withDefaultResilienceStrategy()
                .build();
        cacheManager.createCache("someCacheKey", myCache);
        return cacheManager;
    }
}

However, there is a problem with all our integration tests which are annotated with @SpringBootTest. These tests will spin up the application context and with this are trying to connect to a remote Ehcache instance; which is nto available.

Is there any way to disable this instantiation? Or do I need to spin up something like an embedded Ehcache server for the integration tests to start the application context?

If your application can run with EhCache disabled, you can simply edit the @SpringBootTest annotation to disable EhCache, eg.: @SpringBootTest(properties = {"property.to.disable.ehcache=true"}), guaranteeing EhCache will be disabled only during the test phase.

If your application requires EhCache to be enabled, your best bet is to add a src/test/resources/application.properties file, containing properties (eg. host, port etc.) pointing to a local, possibly test-embedded, instance of EhCache.
