示例1: it
it('should not add meta tag if it is already present on the page and has the same attr', () => {
expect(metaService.getTags('property="fb:app_id"').length).toEqual(1);
metaService.addTag({property: 'fb:app_id', content: '123456789'});
expect(metaService.getTags('property="fb:app_id"').length).toEqual(1);
});示例2: it
it('should extract selector from the tag definition', () => {
const selector = 'property="fb:app_id"';
metaService.updateTag({property: 'fb:app_id', content: '666'});
const actual = metaService.getTag(selector);
expect(actual).not.toBeNull();
expect(getDOM().getAttribute(actual, 'content')).toEqual('666');
});示例3: expect
() => {
expect(metaService.getTags('property="fb:app_id"').length).toEqual(1);
const meta = metaService.addTag({property: 'fb:app_id', content: '666'});
expect(metaService.getTags('property="fb:app_id"').length).toEqual(2);
// clean up
metaService.removeTagElement(meta);
