小编ris*_*ide的帖子

我正努力自学Mockito.

考虑下面的方法hasInventory(),它不应该以我的思维方式运行,而是设置为返回true或false,因为我松鼠笼罩我的测试.Class Warehouse是我的"模仿依赖".

public class Warehouse implements IWarehouse
{
  private Map< String, Integer >    inventory;

  public Warehouse()
  {
    this.inventory = new HashMap< String, Integer >();
  }

  public final boolean hasInventory( String itemname, int quantity )
      throws InventoryDoesNotExistException
  {
    if( inventory == null )
      throw new InventoryDoesNotExistException();

    if( !inventory.containsKey( itemname ) )
      return false;

    int current = ( inventory.containsKey( itemname ) ) ? inventory.get( itemname ) : 0;

    return( current >= quantity );
  } …

在lettable operator之前,我做了一个帮助来修改debounceTime方法,所以它使用了一个TestScheduler:

export function mockDebounceTime(
    scheduler: TestScheduler,
    overrideTime: number,
): void {
    const originalDebounce = Observable.prototype.debounceTime;

    spyOn(Observable.prototype, 'debounceTime').and.callFake(function(
        time: number,
    ): void {
        return originalDebounce.call(
            this,
            overrideTime,
            scheduler,
        );
    });
}

因此,以下Observable的测试很简单:

@Effect()
public filterUpdated$ = this.actions$
    .ofType(UPDATE_FILTERS)
    .debounceTime(DEFAULT_DEBOUNCE_TIME)
    .mergeMap(action => [...])

对于lettable运算符,filterUpdated $ Observable的编写方式如下:

@Effect()
public filterUpdated$ = this.actions$
    .ofType(UPDATE_FILTERS)
    .pipe(
        debounceTime(DEFAULT_DEBOUNCE_TIME),
        mergeMap(action => [...])
    );

我不能修复debounceTime运算符了!如何将testScheduler传递给debounceTime运算符？

我有一个表单和这样的底层模型

来自组件

myTextModel: string;
updateMyTextModel(): void {
    this.myTextModel = "updated model value";
    //todo- set form dirty (or invalid or touched) here
}

Html模板

<form #testForm="ngForm" id="testForm">
  <input type="text" id="myText" [(ngModel)]="myTextModel" name="myText" #myText="ngModel">
</form>
<button (click)="updateMyTextModel()">Update myTextModel</button>
<div *ngIf="testForm.dirty">testForm diry</div>
<div *ngIf="testForm.touched">testForm touched</div>

如何从代码中设置触摸或脏的表单？

注意:在此示例中,我使用按钮来触发模型更改,但我也可能以其他方式更新模型,例如在来自web api异步请求的回调中.

ElementRef我有一个使用下面定义的方法。

@ViewChild('idNaicsRef') idNaicsRef: ElementRef;

ElementRef然后使用 设置焦点.nativeElement.focus()。

该方法在运行规范时失败，提示“未定义是一个对象”

有了Spring4 + ActiveMQ,我想从队列接收JMS消息,并自动转换为POJO.所以我添加MappingJackson2MessageConverter到DefaultJmsListenerContainerFactory

@Bean
public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();

    // some other config

    MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
    converter.setTargetType(MessageType.TEXT);
    converter.setTypeIdPropertyName("???");
    factory.setMessageConverter(converter);

    return factory;
}

这是我的Listener配置

@JmsListener(destination = "queue.fas.flight.order", containerFactory = "jmsListenerContainerFactory")
public void processOrder(OrderRegisterDto registerParam) {
    System.out.println(registerParam.toString());
}

问题是,我不知道如何设置TypeIdPropertyName.队列不在我的控制之下,其他人发送JSON给它.

我想要一个普通的转换器.所以我使用String接收消息,并手动将其转换为POJO.
Spring4 + ActiveMQ
还有更好的方法吗？

我从他们发布它的那天起就一直在使用Angula2 + Universal,但今天我对它的实际工作方式感到困惑.

在他们的示例中,在server.ts文件中,您将找到:

app.get( '/data.json' , ( req , res ) => {
    res.json( {
        data : 'This fake data came from the server.'
    } );
} );

如果您运行该应用程序,右键单击并查看页面源代码,您将在源代码中找到"此伪造数据来自服务器",这意味着该页面已在服务器中呈现？( 它是否正确 ？ )

到目前为止,太棒了.

接下来是app.ts,你可以找到:

ngOnInit () {
        setTimeout( () => {
            this.server = 'This was rendered from the server!';
        } , 10 );
}

同样,该文本也可以在页面源中找到.

现在这里是我的奇怪部分:

如果您出于任何原因增加服务器延迟,如:

app.get( '/data.json' , ( req , res ) => {
    setTimeout( function() {
        res.json( {
            data : 'This fake data …

我正在使用 mat-select 来显示下拉菜单，我需要在 angular 下拉菜单中选择所有功能。

下面是我的html

<mat-select formControlName="myControl" multiple (ngModelChange)="resetSelect($event, 'myControl')">
    <mat-option>Select All</mat-option>
    <mat-option [value]="1">Option 1</mat-option>
    <mat-option [value]="2">Option 2</mat-option>
    <mat-option [value]="3">Option 3</mat-option>
</mat-select>

这是我的 ts 代码

/**
 * click handler that resets a multiple select
 * @param {Array} $event current value of the field
 * @param {string} field name of the formControl in the formGroup
 */
protected resetSelect($event: string[], field: string) {
    // when resetting the value, this method gets called again, so stop recursion if we have no values …

我只在带有atomikos的实时服务器上遇到问题,在我的本地服务器上它完美运行.

我在服务器上的问题是

我是Junit的新手而且我遇到了问题.任何帮助将非常感激.

public void testGuaranteedRates() throws Exception
{

    ParticipantSummary summary = new ParticipantSummary();

    EasyMock.expect( iRequest.getPIN() ).andReturn( "1060720" );
    DateFormat dateFormat = new SimpleDateFormat( "yyyy/MM/dd HH:mm:ss" );
    Date date = new Date();
    EasyMock.expect( iRequest.getTradeDate() ).andReturn( date ).anyTimes();
    EasyMock.expect( control.prepareServiceRequest( iRequest ) ).andReturn( rtvint );
    EasyMock.replay();
    ems.replayAll();
}

prepareServiceRequest()方法如下

org.tiaa.transact.generated.jaxb.inquiry.RetrieveRetirementVintages prepareServiceRequest(InquiryRequest inquiryRequest)
{

    logger.debug( "prepareServiceRequest enter" );
    org.tiaa.transact.generated.jaxb.inquiry.ObjectFactory objectFactory = new org.tiaa.transact.generated.jaxb.inquiry.ObjectFactory();

再次需要帮助!

我正在使用Angular 4,并希望从我的组件中的url获取参数.URL是" http:// myhost/index？user = James&token = 123&picture = 3456abc.png "或" http:// myhost/index？user = Peter "

我试过这些不同的方法,但没有运气.

如何获取网址参数'user','token'和'picture'？

import { Routes, RouterModule, Router, ActivatedRoute, RouteSegment, Params, ROUTER_DIRECTIVES } from '@angular/router';

  constructor(private restSvc: RestSvc, private router: Router, private domSanitizer: DomSanitizer,
    private mdIconRegistry: MdIconRegistry, private activatedRoute: ActivatedRoute, private routeSegment: RouteSegment) {

    // Method 1: subscribe to queryParamMap - not working - all values are undefined
    /*    this.activatedRoute.queryParamMap.subscribe(params => {
          this.userName = params['user'];
