我正在NetworkClientServiceImpl使用 WireMock 技术为我的 Java 类编写集成测试，但我遇到了一些异常，我无法解决它们。
NetworkClientServiceImpl以下是我正在为其编写集成测试的类内部声明的方法。
public Observable<NetworkOptionResponse> getSettingsValues(final NetworkClientQuery networkClientQuery, final String names) throws
NetworkException {
checkArgument(networkClientQuery != null, MISSING_REQUIRED_PARAMETER, "networkClientQuery");
logger.info("Get Networking Settings Values for names:{} and QueryParams:{}", names,networkClientQuery.getQueryParams());
try {
String url = UriBuilder.fromPath("/networkmiddle/settings/{names}").build(names).getPath();
logger.info("UrlPath "+url);
return commandBuilder.build(url, HttpRequest.Verb.GET,NetworkOptionResponse.class,networkClientQuery.getQueryParams()).observe();
} catch (final Exception ex) {
String errorMessage = String.format("Failed to get NetworkSettings Values for names:[%s] with error:[%s]", names, NetworkClientUtils.getErrorMessage(ex));
logger.error(errorMessage, ex);
throw new NetworkException(errorMessage, Response.Status.INTERNAL_SERVER_ERROR);
}
}
NetworkClientServiceImplIT常规文件：
class NetworkClientServiceImplIT extends Specification{
@Inject
NetworkClientService service
@Rule
private WireMockRule middleMock = new WireMockRule(WireMockConfiguration.wireMockConfig().port(19080));
def 'validate config'() {
expect:
service != null
}
def 'Get Settings Values'(){
given:
Builder builder = new Builder();
builder = builder.withQueryParam("device", "000004FA4D88")
builder = builder.withQueryParam("home", "8087300010167669")
builder = builder.withQueryParam("user", "testid195")
NetworkClientQuery query = builder.build();
String names = "Favourites";
String json = '{"settings": [{ "name": "DVS", "value": ["Off"] },{ "name": "Info Banner Duration", "value": ["15"] },{ "name": "Rating Locks", "value": ["TVMA","NC17","NR Mature"] }]}'
ResponseDefinitionBuilder responseBuilder = new ResponseDefinitionBuilder();
responseBuilder.build().setBody(json);
String urlPath = "/networkmiddle/settings/"
middleMock.stubFor(get(urlPathEqualTo(urlPath)).willReturn(responseBuilder))
when:
Observable<NetworkOptionResponse> response = service.getValues(query,names);
println'********* Test1 ******'
println'********* Test2 ******'+response
println'********* Test3 ******'+response.getClass()
NetworkOptionResponse response2 = response.toBlocking().single();
println'********* Test4 ******'
then:
response != null
println '** Response '+response
response2 != null
println '** Response2 '+response2
}
}
当我执行 Maven 全新安装时，我收到以下响应：
