I've encountered an unusual problem that needs to be resolved for me to successfully complete a unit test for a project I'm currently engaged in.
Here is what my unit test currently looks like:
it('should display the navbar list', () => {
component.courses = jsonData.hamburgerMenu[0].menuItems;
fixture.detectChanges;
const links = el.queryAll(By.css(".NavMenuItem"));
expect(links).toBeTruthy("Could not find links");
console.log(jsonData.hamburgerMenu[0].menuItems)
console.log(links);
});
Accompanied by the corresponding HTML code:
<div *ngFor="let appMenuItem of courses; let i=index;" class="NavMenuItem">
The issue arises when I attempt to console.log links with an HTML element lacking an "ngIf" or "ngFor" statement, resulting in a "[DebugElement]." However, if I use an HTML element with an "ngIf" or "ngFor" statement, it simply returns a "[]." This poses a problem as I need to incorporate the following code snippet into my unit test:
expect(links.length).toBe(12, "Unexpected number of links");
Nevertheless, since queryAll(By.css) yields nothing when applied to an HTML component with an "ngFor," this condition becomes invalid. How can I overcome this obstacle?
And for those curious minds, rest assured that the mock data is present. jsonData.hamburgerMenu[0].menuItems comprises the data shown below:
