示例1: it
it('should truncate collection', () => {
let result = pipe.transform(collection, [{ itemsPerPage: 10, currentPage: 1 }]);
expect(result.length).toBe(10);
expect(result[0]).toBe('item 1');
expect(result[9]).toBe('item 10');
});示例2: expect
.then((fixture: ComponentFixture<TestCmp>) => {
let instance: TestCmp = fixture.componentInstance;
instance.config.itemsPerPage = 100;
fixture.detectChanges();
expect(getPageLinkItems(fixture).length).toBe(0);
instance.autoHide = false;
fixture.detectChanges();
expect(getPageLinkItems(fixture).length).toBe(1);
});示例3: tick
.then((controlsInstance: PaginationControlsCmp) => {
testCmpInstance.config.currentPage = 1;
fixture.detectChanges();
tick();
expect(controlsInstance.isLastPage()).toBe(false);
testCmpInstance.config.currentPage = 10;
fixture.detectChanges();
tick();
expect(controlsInstance.isLastPage()).toBe(true);
