How to access Kendo UI grid components in unit test logic (Karma/Jasmine)

[Scott]

Given this HTML, how are grid components (e.g. kendo-dropdownlist) accessed and tested?

<form [formGroup]="computedFormGroup" style="box-sizing:border-box;padding:40px;">
<div style="width:100%">

<h1>Policy</h1>

<kendo-tabstrip ...>
<kendo-tabstrip-tab ...>
<ng-template kendoTabContent>

<kendo-grid ...>

<ng-template kendoGridToolbarTemplate>
<button mat-raised-button color="primary" kendoGridAddCommand>Add new</button>
</ng-template>

<kendo-grid-command-column title="Action" [sticky]="true" [width]="290">
<ng-template kendoGridCellTemplate let-isNew="isNew">
...
</ng-template>
</kendo-grid-command-column>

<kendo-grid-column field="aip" title="AIP" width="200" class="aip_ddl">
<ng-template kendoGridCellTemplate let-dataItem>
{{ dataItem.aip }}
</ng-template>
<ng-template kendoGridEditTemplate
let-dataItem="dataItem"
let-column="column"
let-formGroup="policyFormGroup">
<div class="aip_ddl">
<kendo-dropdownlist [defaultItem]="{ aipCode: null, aipCodeAndName: '' }"
[data]="aipModel"
[popupSettings]="{width:400}"
textField="aipCodeAndName"
valueField="aipCode"
class="aip_ddl"
[valuePrimitive]="true"
[formControl]="policyFormGroup.get('aip')">
</kendo-dropdownlist>
</div>
</ng-template>
</kendo-grid-column>

 

Unit test code:

it('should bind the configured value to the AIP dropdown list.', async(() =>
{
// Arrange
// Set the form group.
component.policyFormGroup = constPolicyFormGroup(data);
// Set the specific data to test.
component.policyFormGroup.controls.aip.setValue('FH');

I want to access and test the dropdownlist here:

                console.log(fixture.debugElement);
const element = fixture.debugElement.query(By.css('form'));
const attr = element.nativeElement.getAttribute('aip-ddl');
//expect(element.nativeElement.getAttribute('ng-reflect-resizable')).toBe('true');
//let select: HTMLSelectElement = fixture.debugElement.query(By.css('.aip_dll')).nativeElement;
//const myComponent = fixture.debugElement.query(By.directive(DashboardComponent));
//let select: HTMLSelectElement = fixture.debugElement.nativeElement.querySelectore('aip_dll');
let p = fixture.debugElement.nativeElement.querySelector('p');
fixture.detectChanges();
//component.aipModel..aip = new FormControl(component.policyFormGroup.controls.aip);
//fixture.detectChanges();
//fixture.whenStable().then(() =>
//{
// let text = select.options[select.selectedIndex].label;
// expect(text).toBe('Manager');
// expect(p.textContent).toBe('Manager');
//});
}));

Hi Scott,

Thank you for the provided code snippet.

Kendo UI for Angular components are using Jest for unit and Protractor for e2e tests.

Additionally, our tests can be viewed as helpful resources by obtaining the source code of the desired package:

https://www.telerik.com/kendo-angular-ui/components/installation/source-code/

The DropDownList inside the Grid isn't unit tested and it's recommended to be e2e tested instead.

I hope this helps.
