### Question:
OidcAuthenticationHelper { public void validateRealm(TokenDetails tokenDetails) { realmService.validateRealm(tokenDetails); } OidcAuthenticationHelper();  OidcAuthenticationHelper(OidcConfiguration oidcConfiguration,
                                    OAuthClient oAuthClient,
                                    SecurityConfig config,
                                    RealmService realmService); String getBearerToken(HttpServletRequest request); String getBearerToken(HttpServletResponse response); TokenDetails getTokenDetails(HttpServletResponse response); String getRefreshToken(HttpServletResponse response); String getAccessToken(HttpServletRequest request); String getRefreshToken(HttpServletRequest request); String createRedirectUrl(String redirectUrlTemplate, HttpServletRequest request); void setRealmForCurrentRequest(String realm); String getRealmForCurrentRequest(); String getRealmForCurrentRequest(HttpServletResponse response); void validateRealm(TokenDetails tokenDetails); void removeRealmFromCurrentRequest(); boolean shouldApplyUrl(String method, String path); boolean shouldApplyUrl(HttpRequest request); boolean shouldSkip(HttpRequest request); void authenticateCurrentThread(String accessToken, String refreshToken); void authenticateCurrentThread(TokenDetails tokenDetails); @Deprecated AccessToken parseAccessToken(TokenDetails tokenDetails); String removeCodeFromUrl(String url, String code); String removeCodeFromUrl(HttpServletRequest request); boolean isTokenExpiredOrShouldBeRefreshed(TokenDetails tokenDetails); @Deprecated TokenDetails generateTokenDetails(String accessToken, String refreshToken); void safeCleanupSecurityContext(Class clazz); @Autowired void setOidcConfiguration(OidcConfiguration oidcConfiguration); @Autowired void setOAuthClient(OAuthClient oAuthClient); @Autowired void setConfig(SecurityConfig config); @Autowired void setRealmService(RealmService realmService); static final String AUTH_HEADER_VALUE_PREFIX; }### Answer:
@Test void validateRealm() { OidcConfiguration oidcConfiguration = new OidcConfiguration(); oidcConfiguration.setDefaultRealm("realm"); oidcConfiguration.setExcludeValidationRealm("mservice"); helper.setOidcConfiguration(oidcConfiguration); TokenDetails tokenDetails = new TokenDetails(); tokenDetails.setRealm("javatar-security"); helper.validateRealm(tokenDetails); tokenDetails.setRealm("javatar-security"); helper.validateRealm(tokenDetails); }
