今天來點輕鬆的，我們幫文章實作一些細節

如果文章內容是圖片連結的話，轉換成圖片

it('內容如果是圖片連結，要顯示圖片', () => {
    let showButton = '.post:nth-child(2) .show-btn'
    let postContent = '.post:nth-child(2) .content'

    click( showButton )
    picture(posts[1].content, `${postContent} img`)
})

<p v-if="post.content && post.show" class="mt-2 content">
    <img class="img-fluid" v-if="isImage(post.content)" :src="post.content">
    <span v-else v-text="post.content"></span>
</p>

methods: {
    ...
    isImage: function (content) {
        return content.match(/\.(jpeg|jpg|gif|png)$/) != null
    }
},
