Imagine having a straightforward function that includes a for statement:
public loadImages(images): void {
for (let image of images) {
this.imageLoader.load(image['url']);
}
}
When attempting to spy on imageLoader.load, the testing process fails. However, if the function is adjusted to call load outside the loop, the test succeeds.
it('should load images using the loader', inject([ImageService, ImageLoader], (
service: ImageService,
imageLoader: ImageLoader) => {
spyOn(imageLoader, 'load');
service.loadImages({ 'url': 'example.com/image1.jpg' });
expect(imageLoader.load).toHaveBeenCalled();
}));
Upon checking console logs, it appears that the loadImages function is being executed, but the for loop itself is not being entered. What could be causing this behavior?
