單元測試給假值由構造

Question

初始化變量我有一個類

Test.ts：

class Test 
{ 
    public property1: string; 
    public property2: boolean; 
    constructor(property1, property2) 
    { 
      this.property1 = property1;//will get value while instantiation 
      this.property2 = property2;//will get value while instantiation 
      this.property3 = somevalue;//want to add fake value here 
    } 
} 

給出上面我想給一個假值property3但property1和和property2我會從實例化中獲得它。我怎樣才能做到這一點？

Answer 1

我相信你正在努力宣佈property3成員。只需像你宣佈的其他屬性那樣做。其他可以使用屬性初始化，如果你想：在打字稿類

class Test 
{ 
    public property1: string; 
    public property2: boolean; 
    public property3 = somevalue; 
    constructor(property1, property2) 
    { 
      this.property1 = property1;//will get value while instantiation 
      this.property2 = property2;//will get value while instantiation 
    } 
}
