茉莉花单元测试中带有参数的按钮单击（角度）

Question

我正在按角度编写按钮单击事件的单元测试。下面提到的按钮单元测试在功能未参数化的情况下可以很好地工作-

如果可以的话，它将起作用：

(click)="editForms()"

但是当我在函数中添加参数时，就像这样：

(click)="editForms(array) , the this test fails as - "Failed: Cannot read property 'click' of null" --

它无法调用函数editForms。

有人可以告诉我该怎么做吗？

  beforeEach(() => {
    fixture = TestBed.createComponent(MyjobsComponent);
    component = fixture.componentInstance;
     fixture.detectChanges();
  });

    fit('should do editForms button click ', async(() => {
        spyOn(component, 'editForms');
        let button = fixture.debugElement.nativeElement.querySelector('button');
        button.click();
        fixture.whenStable().then(() => {
          expect(component.editForms).toHaveBeenCalled();
        })
      }));

HTML：

 <button mat-raised-button style="background-color:#6666ff;color:white;" (click)="editForms(array)"> <i class="material-icons">create</i></button>

component.ts：

editForms(name) {
    console.log(name);
    console.log( this.totalJobData);
    for(let e = 0; e < this.totalJobData.length; e++){
      if(this.totalJobData[e].jobName === name){
        this.jobID = this.totalJobData[e].jobId;
        this.sourceCode = this.totalJobData[e].sourceCode;
      }`enter code here`
    }
    console.log(this.sourceCode);
