Thanks, see if you can fix the lint issue in components/Blog/BlogCard/index.module.scsshttps://github.com/nodejs/nodejs.org/actions/runs/4775331933/jobs/8489525157?pr=5323

From the Stories, it looks like that:

• The colour of the title and font weights seem to be wrong
• The date formatting needs to be corrected? I guess you should use FormattedDateTime with something that makes "Month Day, Year" (e.g. "June, 21, 2022)
• After category, there should be a read time span

Example how it should look like:

I've made the requested changes

We're almost there. But impressive work!!

[Harkunwar]

@ovflowd I feel like there's a lot of duplication in the way we're writing unit tests and stories. If we could directly import stories in our unit tests, we'll have less duplication. Storybook already allows it, so would it be worth doing that?

[Harkunwar]

If I add this to our jest.setup.mjs, it will allow us to use decorators defined in .storybook/preview.

import{setProjectAnnotations}from'@storybook/react';import*asglobalStorybookConfigfrom'./.storybook/preview';setProjectAnnotations(globalStorybookConfig);Object.defineProperty(window,'matchMedia',{writable: true,value: jest.fn().mockImplementation((query)=>({matches: false,media: query,onchange: null,addListener: jest.fn(),removeListener: jest.fn(),addEventListener: jest.fn(),removeEventListener: jest.fn(),dispatchEvent: jest.fn(),})),});

Then we won't need to use IntlProvider anymore and our snapshot tests could become as simple as:

import{render}from'@testing-library/react';import*asstoriesfrom'../index.stories';import{composeStories}from'@storybook/react';const{ Default }=composeStories(stories);jest.mock('next/router',()=>({useRouter: jest.fn().mockReturnValue({}),}));describe('BlogCard component',()=>{it('renders correctly',()=>{const{ container }=render(<Default/>);expect(container).toMatchSnapshot();});});

And we can start using the stories in other tests as well instead of duplicating them multiple times.

@Harkunwar feel free to create an issue and work on a PR updating all tests to the approach you're suggesting :)
