单元测试给假值由构造

Question

初始化变量我有一个类

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 
    } 
} 

给出上面我想给一个假值property3但property1和和property2我会从实例化中获得它。我怎样才能做到这一点？

Answer 1

我相信你正在努力宣布property3成员。只需像你宣布的其他属性那样做。其他可以使用属性初始化，如果你想：在打字稿类

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 
    } 
}
