我正在尝试录制一些XCUITesting函数.我收到这个错误.

Timestamped Event Matching Error: Failed to find matching element

这是一个Xcode错误和/或我的UI的复杂性问题？

我在teamcity的构建日志中有一个警告.我已经将我的CI-Server上的Xcode从7.3.1更新到8.步骤成功运行但我有:

[Step 3/3] Starting: /Users/teamcity/local/teamcity-build-agent/temp/agentTmp/custom_scriptxxxxxxx

我该如何修复此警告？

我不明白为什么我的代码不起作用.这里是:

class Test: NSURLSessionDataDelegate {

    func URLSession(session: NSURLSession, task: NSURLSessionTask, didCompleteWithError error: NSError?) {

        if(error == nil) {
            print("Hallo")
        } else {
            print(error?.userInfo)
        }
    }

    func createRequest() {

        let dictionary = [
            "mailAddress":"foo@example.com",
            .....
        ]

        let nsData: NSData?
        do {
            nsData = try NSJSONSerialization.dataWithJSONObject(dictionary, options: NSJSONWritingOptions(rawValue:0))
        } catch _ {
            nsData = nil
        }

        let defaultConfigObject = NSURLSessionConfiguration.defaultSessionConfiguration()
        let defaultSession = NSURLSession(configuration: defaultConfigObject, delegate: self, delegateQueue: NSOperationQueue.mainQueue())
        let url = NSURL(string: "http:...")!
        let urlRequest = NSMutableURLRequest(URL: url)
        urlRequest.HTTPMethod = "POST" …

我使用 spring boot oauth 2 创建了一个授权。我无法使用数据库中的数据获取访问令牌。

我的授权服务器：

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private PasswordEncoder passwordEncoder;

    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private PropertyConfiguration propertyConfiguration;

    @Override
    public void configure(final AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }
    @Override
    public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient(propertyConfiguration.getPasswordId())
                .secret(passwordEncoder.encode(propertyConfiguration.getPasswordSecret()))
                .authorizedGrantTypes("password")
                .scopes(SCOPE_WRITE)
                .autoApprove(true);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
                .tokenStore(tokenStore())
                .authenticationManager(authenticationManager);
    }

    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }

我的主课：

@SpringBootApplication
@EntityScan(basePackages = …

当我运行我的代码时,我得到这个例外:

我想检查一下我的ui上以前缀开头的元素是否存在.如何在Xcode 7 UI测试中实现它？

app.tables["AAA"].staticTexts["Fax: 0049XXXXXXXX"].exists

我有三个元素进入tableview单元格,只有一个元素(第三个或最后一个)以前缀Fax:0049开头.如何查看此元素的当前内容？

我试过了

app.tables["AAA"].cells.staticTexts.elementBoundByIndex(2).exists

但没什么,有些想法？干杯

我的一个控制器中的构造函数有一些问题。我尝试在构造函数中调用一项服务。该服务在 AbstractController 中自动装配，但我得到了一个空指针异常。

一个组件：

@Component
@RestController
@RequestMapping(value = "/test", ...)
public class AController extends AbstractController {

    @Autowired
    SomeService someService;

    public AController(){
        globalService.setClazz(Test.class);
    }
....

这里是抽象控制器：

public abstract class AbstractController<T> {

    @Autowired
    GlobalService globalService;

    ...

这里例外。它被扔进去globalService.setClazz(Test.class);

 Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.x.server.controller.AController]: Constructor threw exception; nested exception is java.lang.NullPointerException -> [Help 1]

我试图从流中获取一个列表,但我有一个例外.

这是带有对象列表的Movie对象.

public class Movie {

    private String example;
    private List<MovieTrans> movieTranses;

    public Movie(String example, List<MovieTrans> movieTranses){
        this.example = example;
        this.movieTranses = movieTranses;
    }
    getter and setter

这是MovieTrans:

public class MovieTrans {

    public String text;

    public MovieTrans(String text){
        this.text = text;
    }
    getter and setter

我在列表中添加元素:

List<MovieTrans> movieTransList = Arrays.asList(new MovieTrans("Appel me"), new MovieTrans("je t'appel"));
List<Movie> movies = Arrays.asList(new Movie("movie played", movieTransList));
//return a list of MovieTrans
List<MovieTrans> movieTransList1 = movies.stream().map(Movie::getMovieTranses).collect(Collectors.toList());

我有这个编译错误:

Error:(44, 95) java: incompatible types: inference variable T …

我有两个对象.第一个:

public final class Object1 {
    private String a;
    private String b;
    // constructor getter and setter
}

第二个:

public class Object2 {
    private BigDecimal value1;
    private BigDecimal value2;
    // constructor getter and setter
}

我有一个Map<Object1, Object2>:

    Object1{a="15", b="XXX"}, Object2{value1=12.1, value2=32.3}
    Object1{a="15", b="YYY"}, Object2{value1=21.1, value2=24.3}
    Object1{a="16", b="AAA"}, Object2{value1=34.1, value2=45.3}
    Object1{a="15", b="BBB"}, Object2{value1=23.1, value2=65.3}
    Object1{a="15", b="DDD"}, Object2{value1=23.1, value2=67.3}
    Object1{a="17", b="CCC"}, Object2{value1=78.1, value2=2.3}
........

我想在Object2列表中使用相同的a对此映射进行分组,如:

a="15", {{value1=12.1, value2=32.3}, {value1=21.1, value2=24.3}, {value1=23.1, value2=65.3}, {value1=23.1, value2=67.3}},
a="16", {{value1=34.1, value2=45.3}}
...

我尝试这样的事情:

Map<String, …

WebSecurityConfigurerAdapter：

@Component
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter

               .authenticated()
               .and()
               .csrf()
               .disable()
               .httpBasic();
   }

   @Override
   public void configure(AuthenticationManagerBuilder auth) throws Exception
   {
      auth.ldapAuthentication()
          .userDnPatterns("uid={0},ou=people")
          .userSearchBase("ou=people")
          .userSearchFilter("uid={0}")
          .groupSearchBase("ou=groups")
          .groupSearchFilter("uniqueMember={0}")
          .contextSource()

          .passwordCompare()
          .passwordEncoder(passwordEncoder())
          .passwordAttribute("userPassword");
   }

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