I am trying to write unit test cases for Grid, for this I need to loop through gridapi data but it is giving me Cannot read undefined forEachNode error.
myComponent.component.ts.
import { Component, OnInit, } from '@angular/core';
import { GridOptions, GridApi, } from "ag-grid-community";
@Component({
selector: 'my-component',
templateUrl: './mycomponent.component.html',
styleUrls: ['./mycomponent.component.scss']
})
export class MyComponent implements OnInit {
grid: GridOptions;
data;
constructor() {}
getData() {
this.grid.api.forEachNode((node) =>
this.data.push(node.data.id);
);
}
}
mycomponent.component.spec.ts:
import { ComponentFixture, TestBed, waitForAsync } from '@angular/core/testing';
import { Mycomponent} from './mycomponent.component';
describe('Mycomponent', () => {
let component: Mycomponent;
let fixture: ComponentFixture<Mycomponent>;
beforeEach(
waitForAsync(() => {
TestBed.configureTestingModule({
declarations: [Mycomponent],
}).compileComponents();
})
);
beforeEach(() => {
fixture = TestBed.createComponent(Mycomponent);
component = fixture.componentInstance;
const gridObj = jasmine.createSpyObj('grid', [
'api',
]);
gridObj.grid.api.and.returnValue({
context: {}
data : { id:1,name: 'columName'}
});
component.grid = gridObj;
fixture.detectChanges();
});
it(`should call getData method.`, () => {
component.getData();
expect(component.data).toEqual('[1]');
});
});
When I try to run above test case, TypeError: Cannot read properties of undefined (reading 'forEachNode'). Can any one tell me where I am doing wrong.
