茉莉AG网格测试案例失败

发布于 2025-01-26 05:50:16 字数 745 浏览 4 评论 0原文

我正在尝试编写用于Ag网格导出方法的测试。这是组件更改

export class GridComponent extendsimplements OnInit {

  gridApi: any;

  onGridDataExport(): void {
    this.gridApi.exportDataAsCsv();
  }
}

网格组件规格文件

fdescribe('when onGridDataExport method call', () => {
    it('should call gridApi', () => {
      const result = spyOn(component.gridApi, 'exportDataAsCsv');
      component.onGridDataExport();
      expect(result).toHaveBeenCalled();
    });

  });

当我运行测试用例时，它显示以下错误

我该如何解决此问题？

期望有效的解决方案。

提前致谢

Am trying to write a test for ag grid export method.
Here is the component changes

export class GridComponent extendsimplements OnInit {

  gridApi: any;

  onGridDataExport(): void {
    this.gridApi.exportDataAsCsv();
  }
}

grid component spec file

fdescribe('when onGridDataExport method call', () => {
    it('should call gridApi', () => {
      const result = spyOn(component.gridApi, 'exportDataAsCsv');
      component.onGridDataExport();
      expect(result).toHaveBeenCalled();
    });

  });

when i run the test cases it show the below error

How can i resolve this issue?

expecting a valid solution.

Thanks in advance

尝试以下尝试：

fdescribe('when onGridDataExport method call', () => {
    it('should call gridApi', () => {
      const result = spyOn(component.gridApi, 'exportDataAsCsv').and.callThrough();
      component.onGridDataExport();
      expect(result).toHaveBeenCalled();
    });
});

如果您查看我的代码，我正在添加.and.callthrough（）;，并且您需要使用它，因为使用此代码，您真的在等待执行方法<代码> exportDataAscsv 。

Try with this:

fdescribe('when onGridDataExport method call', () => {
    it('should call gridApi', () => {
      const result = spyOn(component.gridApi, 'exportDataAsCsv').and.callThrough();
      component.onGridDataExport();
      expect(result).toHaveBeenCalled();
    });
});

If you look my code, I'm adding .and.callThrough(); and you need to use this because with this code you're really waiting for the execution of the method exportDataAsCsv.
